Overview - This articles outlines a fast method for anyone to form their own opinion of the popularity of any Computer Optimization Program (e.g. Registry fix software, registry cleaner software, error fixing software etc..). It also uses the real life example of a website dedicated to help users fix computer errors, which has already adopted this method for screening relevant software for further review.

Readers should be aware that, although the method described in this article is new and not perfect, it does present a distinct advantage over most other alternatives.   

The problem - Despite the range of software claiming to optimize computer performance, most computer users do not tend to rely on impartial information in order to verify the popularity of Computer Optimization Software before making their purchase. This is a challenge, because Computer Optimization Software which are popular also tend to be proven and effective. Conversely those which are not may be new, unproven or both and are inherently riskier.

The options - Most users still rely on forums. This method is problematic, in that forums only provide anecdotal evidence of the popularity of any software, another challenge is the risk that participants will promote their own products using forums rather than share any independent perspective.

Software vendors’ sites provide another method. The trouble is that software vendors are obviously partial to their products, and this is the downside of using this method.

Another option, is to review independent sites, which usually compare several computer optimization software in the same category for instance Anti-Virus software, Registry Repair Software, Anti Adware/ Spyware software etc… The problem with this method is that 99% of these sites go straight into the details of the technical features, and that they do not give an independent perspective of the popularity of the products they are comparing, as they lack the data to do so.

So how can users determine the popularity of any computer optimization software independently? (Click on the registry fix software example)

15 Minutes Method - A superior method is to look at the data provided by digital market places such as Clickbank for example, which is the largest of them all. Many of the most popular Computer Optimization Software are sold at least partly through digital market places and are given an indicator of popularity known as Gravity. This indicator is usually linked to the volume of sales for a particular software over a period of time. The Gravity measure of any digital product is calculated and compared independently from any software vendor by Clickbank. This indicator is therefore a good independent measure of popularity. Users can in any event, independently verify the actual popularity of any Computer Optimization Program by visting Clickbank or a similar digital marketplace. In spite of the fact that the method has inherent limitations (i.e not all Computer Optimization Software are sold via Clickbank), it is still one of the most accessible to follow independently.

Example - Some software review sites have adopted this method and are now referring to the Clickbank popularity of the digital products that they are also reviewing independently (Click on fix registry errors for a live example). 

This article exposes the downside of relying on free software to block popup ads in the wider context of adware and spyware protection.

Adware are commonly defined as any type of software which plays, displays or downloads advertisements on computers. Some adware are known as spyware due to their function, which consists of collecting then sharing some personal information about the users without their knowledge or consent. 

Adware popups have become a common irritation for most users and many are now looking for free ways to disable them. The preferred solution for many users is to rely on the popup blocker function of either the Google or MSN toolbar. Most users do not realise the link between popups and spyware, very few take the right steps to protect themselves and the majority of users concentrate on just blocking popup ads. Yet, in order to protect the users’ privacy, preserve the integrity of their computers, and make any computing experience a pleasant one, both removal and prevention are important. This contrasts with just blocking popups, which simply creates a false sense of security. This is due to the fact that in reality, the most serious problem with popup ads is not that they are a permanent irritation, but rather that they are the symptom of spyware infection. This issue is clearly evidenced by the fact that many popups appear when computers are not even connected to the Internet.

Changing the browser settings is free and a step in the right direction

Blocking adware popups whilst browsing is easy enough. Changing the privacy settings so that popups can no longer appear on screen can be done as follows:

·      Select Control Panel in your computer 

·      Click on the Internet Options icon 

·      Click on the Privacy tab. 

·      There is a box next to “Turn on Pop Up Blocker”. 

·      Tick this box and you will block adware popups. 

Once the settings have been changed, users should adjust the privacy levels on their computer. Another option is to use the MSN or Google toolbar. Either toolbar can improve security when browsing the Internet. For more information, click on free popup blockers.

But, what about achieving full protection? Are most users missing the bigger picture?

Unfortunately most users focus on just blocking adware popups, and forget that their computer is probably already infected with adware and spyware. Popup blocker programs like those included with the Google and MSN toolbars are useful, yet have inherent limitations. The main limitations is that they are only dealing with one aspect of the protection required to safeguard the users privacy and the integrity of their system. For more information click on block spyware.

It is highly advisable, to think more broadly about the methods to safeguard the users privacy, and the integrity of their computers against the threat of adware and spyware attacks. In addition to running an anti-virus software that is up to date, users should remove the spyware and adware on their computer. Adware and spyware are frequently downloaded without the users’ knowledge.

The most popular adware and spyware removal tools can both block and get rid of adware and spyware. The most popular adware and spyware removal tools benefit from frequent updates, which rely on research teams who review the latest adware and spyware threats. Using adware and spyware removal programs deals with the root causes of adware and spyware infections by removing undesirable software then blocking adware and spyware. This approach is clearly superior to the reliance on free popup programs. For more information click on adware spyware removal.

This article describes the disadvantages of relying on freeware to block popups, in the wider context of adware and spyware protection.

A common definition for adware is that of any software which runs, displays or downloads ads on computers. Some adware are called spyware because their functions are invasive: They consist of obtaining then sharing some personal information about the users without their consent or knowledge. 

Adware popups have become a common irritation for most users and many are now looking for free ways to disable them. For many users, using free popup blockers such as the Google and MSN toolbars is the preferred solution. Most users do not realise the link between popups and spyware, very few take the right steps to protect themselves and the majority of users concentrate on just blocking popup ads. Yet experience shows that both the removal of adware and spyware, as well their prevention are necessary steps to protect users privacy, preserve the integrity of their systems and enable a pleasant on line experience. This contrasts with the false sense of security which can result from just relying on blocking popups. This is because the most serious problem with popups is not just that they are “irritating”, but rather that they are often the symptom of spyware infection, as is demonstrated by popups appearing when users are not even connected to the internet.

Changing the browser settings is free and a step in the right direction

Blocking adware popups whilst browsing is easy enough. Changing the privacy settings so that popups can no longer appear on screen can be done as follows:

·      Select Control Panel in your computer 

·      Click on the Internet Options icon 

·      Click on the Privacy tab. 

·      There is a box next to “Turn on Pop Up Blocker”. 

·      Tick this box and you will block adware popups. 

Once the settings have been changed, users should adjust the privacy levels on their computer. Another solution is to use the Google or MSN toolbar. Browsing the Internet can be safer with either toolbars. For more information, click on free popup blockers.

But, how about achieving complete protection? Are most users seeing the bigger picture?

Unfortunately, most users simply focus on blocking popups then forget that their computer is probably infected with adware and spyware. Popup blocker software, like those which user can access with the Google and MSN toolbars, are undoubtedly useful, however they only deal with one aspect of protection against privacy invasion, and threats to computer integrity. For more information click on block spyware.

It is highly advisable, to think more broadly about the methods to safeguard the users privacy, and the integrity of their computers against the threat of adware and spyware attacks. Users should, in addtion, run the latest version of their anti-virus software, then eliminate adware and spyware using appropriate tools. Adware and spyware are frequently downloaded without the users’ knowledge.

Typically, the removal of adware and spyware is easily achieved with the most popular adware and spyware removal tools which can also block popups. The most popular adware and spyware removal programs rely on research teams to detect and review the latest known threats. These software are frequently updated. Adware and spyware removal software can also block malicious programs . This method is therefore far superior than just relying on free popup blocker programs.

This article describes simple steps that anyone can follow to rapidly speed up their computer. Step 1 or Step 2 in this article can generally be implemented within 15 minutes with a PC or a Mac.

Step 1 -  Clean the computer registry

Slow computers often have errors in their registry. The registry is similar to the nervous system of the computer and its function is to connect software hardware and computer files. Typically the computer registry becomes more prone to errors over time, is frequently corrupted, and this slows down the computer. Locating then fixing errors in the registry is therefore frequently required. Despite the fact that it is possible to repair the registry manually in theory, this method is not recommended. The main reason for this, is that it requires strong knowledge of the structure of the registry as well as its functions. Using a registry cleaner software is a faster, more reliable option to eliminate errors, redundant files, incorrect links and deal with ActiveX components. Click on fix computer registry for more information.

Step 2 – Delete and block adware and spyware

Another common reason leading to computers slowing-down, is the large number of spyware and adware, which are downloaded from the Internet, often without the users knowledge. Typically this occurs when downloading videos, music or other files from peer to peer (P2P) networks. A simple solution to make any computer faster is to run an anti spyware or adware program to scan, remove then block these unwanted malware. It helps to test the relevant anti spyware or adware program by downloading a trial version as most of them are free. Among the key features to consider are Ease of Download and Simplicity of Use, Automatic Backup, Quality of Customer Service, and of course the overall effectiveness of the software. The best software tend to be the simplest to use and rely on a research capability that constantly updates the software for new threats. Click on best adware spyware removal for more information.

Step 3 – Eliminate viruses

Unsurprisingly many computer viruses can slow down computers and drive down response times. Often viruses damage computer files and use excessive resources such as large amount RAM and disk space. In order to overcome these problems, as well as optimise performance, users should run the latest version of the best anti-virus programs. In the end, they will also be in a stronger position to improve their computer performance.

Step 4 – Simple housekeeping tasks

There are many simple housekeeping tasks which can be done to improve the speed of any computer, for example uninstalling any software that is not needed.  Stopping programs launching automatically is also useful to speed up any computer and is usually very straightforward. These simple steps usually produce small improvements.

Step 5 – Optimise the Hard disk

For hard disks which are smaller than 2GB then at least 200MB of disk should be kept free and at least 500MB for larger hard disks. The amount of free space on the hard drive is a key factor of performance as it is used by temporary files needed by software to run. This free space also enables your computer to swap files as the computers starts using virtual memory (when it runs out of RAM). In that event, unless sufficient  space is free on the hard disk, the system slows down significantly. To check the hard disk itself it is recommended to use a disk scanning programs such as Scandisk for Windows. For instance whilst some hard disks may be large enough, they may be too fragmented with some sectors being unusable. Using a defragmentation program will also improve any computer’s speed. 

Step 6 – Optimising the RAM

Some programs are poorly designed and do not release RAM resources after they are closed. This reduces the amount of memory available for other programs. Running out of RAM too fast is not uncommon and users who have this problem should consider upgrading the memory on their computer. Alternatively running certain programs simultaneously should also be avoided, this option is of course free.

Step 7 – Stop the computer from overheating

Faulty fans are a common cause leading to the computer overheating, slowing down then freezing as a result. The best solution is often to replace the fan, this overcomes the problem by increasing the air flow through the computer thereby reducing its temperature and ultimately improving reponse times.

Certification test

Welding Certification is a big deal.  Jobs that Require welding like Nuclear Plants, Bridge construction, Aerospace, petro/chemical usually require a welder to pass a welding certification test before welding on anything.

But what about the thousands of hobbyist welders out there who buy a 115 volt flux core mig welding machine from Lowes, Home Depot, Tractor supply or even Craiglist?.

keep all the arc strikes in the weld so that they will be covered by the weld. No welding codes allow arc strikes outside the weld.

keep grinding marks and chipping hammer marks confined to the beveled groove area . leaving chipping hammer pecks all over the place is like tattooing the word “Hack” on your forehead.

This could be handlebars for a chopper, a bike rack for the back of a Jeep, a landscape trailer, or a deer stand. (All of which could kill someone if the welds failed).  The next best thing to certifying a welder is to destructively test the weld.

Clean the metal. That means the backing strip and both plates. Get all the mill scale off. Sure the stick will burn right through and sure you will not clean everything that well in the field but this is a test.

Either chip and brush on every tie in or light right back up while things are still hot…one or the other.

Keep all arc strikes within the bevel where they will be consumed with weld.

You are gonna be a little nervous. Be ready for it. Even after over 30 years of welding, I still get nervous.

The best way to not be nervous is to be practiced up for the test. If you called the super beforehand and have practiced the exact test you will be taking, your chances of passing are much better and your brain will know it.

Adware should be eliminated - Adware are software often designed to display ads, which frequently reduce computer speed and cause further issues. They slow down your computer by using RAM and PCU cycles and can also slow down your Internet connection. This article provides guidance, which anyone can follow to remove adware from any system.

Rule 1: Use Adware remover software - Our recommended solution is simply to use an adware removal software and follow some simple steps to prevent undesirable adware installation on your computer. Free Adware tools can be used first – It is generally straightforward to use the free version of popular adware removal tools. This method is a good one, to check if a software meets your needs as well as experience any support and customer service. Click on how do I get rid of adware for more information

Rule 2: Avoid P2P- It usually pays to be cautious with the programs you download from the internet. For example software, which can be downloaded using Peer to Peer networks (Peer to Peer/P2P software) should not be used. In practice many of these programs leave computers open to virus threats, by often installing adware or their hard drives. The fact remains that Peer to Peer networks are widely used to share music and films, and this constitutes a challenge for many users. You should recognise whether you are likely to use P2P and if so, you should use your adware remover software shortly after any download from a peer to peer network to remove any unwanted adware.

Rule 3: Be wary of unpromted emails – Another good habit is to prevent adware being downloaded on your system by not opening emails from unknown senders, this is particularly recommended for emails with attachments. Remember, email messages which look too good to be true probably are and should be deleted. Click on how to remove spyware for more information

Rule 4: Disable cookies -  Unless you know and trust the site you are browsing, you should disallow cookies. Cookies were once meant to make browsing the Internet easier by enabling websites to recognise you, but cookies also open the door to adware, including spyware which are programmed to copy and send important user information, which can ultimately end up in the wrong hands.

Protecting personal information from spyware requires above all a change of behaviour from the user’s perspective. This article describes three simple, yet powerful habits which computer users should develop to safeguard their personal information from spyware threats.

Adware Vs Spyware - The definition of adware is simply that of any type of software package that automatically plays, displays or download advertisements on your computer. Software which intrude in computers to steal and share user’s information are commonly known as spyware. Spyware assist third parties in stealing important user information, and for this reason alone, everyone should learn how to get rid of them. Click on how to remove adware for more information. 

Habit No 1 – Avoid Freeware. Undoubtedly, downloading songs, movies, and other files for free is tempting and may feel like a bargain at the time. Practically though, users may end up getting into more issues than they bargained for, when using freeware and peer to peer programs. Users are often unaware of the fact that downloading these software also lead to setting up adware on their systems.

Ultimately you will safeguard your personal information by being selective about the downloads you accept and these should originate from trusted sources only. 

Habit No 2 – Ignore Pop Ups. Like so many before you, you may have had the displeasure to experience popup ads, clicked on them opened your computer to spyware threats. Popup blocker software are useful in this context, and the good news is, that some of them are even free, like those in the MSN and Google toolbar which will keep popups at bay whilst you browse. The downside of these free programs however, is that they do not deal spyware already installed on your computer, and that they create a false sense of security for many users. Click on block spyware for more information. 

Habit No 3 – Be sure of what you install -You may be wondering also how you even exposed your computer to spyware threats in the first place. Well the answer may surprise you: Often, seemingly minor day to day activities can expose your computer. For example, you may be visting an internet site and be targeted with a dialogue box which may require a decision to install a piece of software. It is tempting to click “OK” or “YES” to any suggested download, however you should know that many sites use this technique to plant spyware on your computer. It is a sad fact of the internet today that some programs or files cannot be downloaded unless spyware end up on your hard disk as well. We hope that you will, from know on, avoid any download from unfamiliar sources as part of your strategy to block adware and spyware. Unless the purpose of any software is made clear, users should not download them. Be particularly cautious when you are visiting unfamiliar sites and are instructed to download something.

The aim of this article is to equip the reader with practical advice on how to resolve the most common causes of errors in their computers. Each step can usually be implemented in 15 minutes or less.

Most Common Computer Errors - Computers have brought dramatic changes in our day to day lives, yet like any machine, they need regular maintenance and upgrade. There are many simple tasks which will fix computer problems and prevent errors.

In the majority of cases, errors exist in the EXE, DLL and driver files. This occurs often due the fact that invalid or corrupt entries have been made in the registry. Files such as these are critically important as they write entries in the registry and these entries are later used to operate the system effectively. If a registry becomes damaged or unstable then the number of random responses and the actual response time increase dramatically.

Run Defragmenter - To begin with, run a disk defragmenter. This operation stores the many parts of the many files on the hard disk closer together and contiguously.Defragmenter use compaction to create large areas of free space on the hard drive and this means that the computer can find information faster with less errors overall.

Registry Scan - In order to fix computer errors in the registry, it is also advisable to complete periodic registry scans, as this enables unwanted data to be detected and subsequently deleted. Registry repair software are ideal to complete this operation easily. There are many advanced registry cleaner software which can perform several registry maintenance tasks, for instance deleting malicious spyware and viruses, scanning and repairing computer errors in the registry, in addition they can perform registry backup as well as defragmenting the registry. Click on fix computer errors for more information.

Remove Spyware and Viruses - Spyware and virus programs create most of the computer errors. Computer viruses are malevolent software, which can also reduce computer response time. This contrasts with software programmed to copy malicious code onto the computer in order to steal confidential data (spyware). This code is frequently sent to third parties later for malicious use. Updating any anti-spyware and antivirus tools is a common sense approach, which anyone can follow in order to fix computer errors. Click on adware and spyware removal for more information.

Fix Boot Sector - Faulty programs, in addition to virus infections can also damage computer boot sectors, and this can prevent the system from booting. In order to fix computer errors, which relate to booting, it is advisable to use the relevant operating system booting CD usually provided with your computer. For instance, XP users can use the relevant operating system to repair the Windows installation.

Upgrade Your RAM - Insufficient memory is another source of errors, which can lead to various computer problems. Usual symptoms of these problems include the system crashing, blue screen, system hanging, sudden reboot and programs crashing and becoming unstable. Fixing computer errors that relate to memory can often be achieved with freeware, which help resolve RAM and related issues. These programs are easy to use and also grealy improve computer performance. Completing a computer memory test is also highly advisable in that event.

Overview - This article describes a fast method that anyone can use to independently assess the popularity of any computer optimization software (e.g. Registry fix software, registry cleaner software, error fixing software etc..). It also uses the real life example of a website dedicated to help users fix computer errors, which has already adopted this method for screening relevant software for further review.

Readers should be forewarned that this method is still new and imperfect, yet that it still represents a superior alternative to most of other approaches available .   

The problem - Never has the choice of computer optimization programs been so large, yet most computer users do not tend to rely on impartial information to verify the popularity of computer optimization software before buying their preferred solution. This is problematic because computer optimization software which are not popular are either new, unproven or both. Either way they are riskier.

The options - Most users still rely on forums. However the problem with this method is that forums only provide anecdotal evidence (at best) of the popularity of any software, another downside is the risk that forum participants are just promoting their own products instead of sharing their independent opinion.

Software vendors’ sites provide another method. The trouble is that software vendors are obviously partial to their products, and this is the downside of using this method.

Another method is to rely on an independent site, which compares different computer optimization software in the same family, for instance Anti-Virus software, Registry Cleaning Software, Anti Adware/ Spyware software etc…. An inherent downside of this method is that 99% of these sites limit their review to the main technical features of the software they are comparing and do not refer to any external independent indicator of popularity as they lack the data to do so.

So how can users determine the popularity of any computer optimization software independently? (click on registry fix software example)

15 Minutes Method - A superior method is to look at the data provided by digital market places such as Clickbank for example, which is the largest of them all. Digital market places are now selling many of the most popular computer optimization software and also give these software an indicator of popularity often called Gravity. This indicator is usually linked to the volume of sales for a particular software over a period of time. Clickbank calculate and compare the gravity measures of any digital product independently from any other software vendors. Gravity is therefore a good independent measure of popularity. Anyone can independently verify the real popularity of any computer optimization software visiting Clickbank or another digital marketplace. Eventhough this method also has its own limitation (some Computer Optimization Software may not be sold through Clickbank), the fact remains that it is one of the most accessible method of independent review today.
