How PC Repair Tools Will Optimize Your Computer

Posted by Kat

While you can wait for errors to manifest themselves on your PC, why not use some PC repair tools before the problems start?  Using PC repair tools on your computer just as a precaution will prevent a host of computer problems and optimize computer performance, bringing it to a new level.  Who’s ready for little guided tour?

Routine Error Repair Tools

Whether you have noticed or not, an unmaintained PC is accumulating various errors all the time.  Sometimes those errors take a while to manifest themselves, but you don’t have to wait until they show up and cause problems to take care of them.

For example, “fragmentation” of files happens no matter what you do, and unless you use the Disk Defragmenter tool, this situation won’t be fixed.

  • Locate this tool under My Computer and right-click on the disk you want to check.
  • The Disk Defragmenter is under Preferences and then Tools.

Hard disk errors also accumulate from routine computer use.  If these are not addressed they can be the cause of error messages in the future.  Fortunately, a repair kit in the form of the Check Disk tool is also provided with your computer.

  • This is also located under My Computer by right-clicking on your hard disk.
  • Again, go to the Preferences window and then Tools.
  • A dialogue box will appear with the option to Check Disk Now.

Choosing Other Computer Repair Tools for Your PC

If you are starting to see a lot of file errors or registry errors (which can be anything from DLL and EXE errors to blue screen messages and program freezes), you will need to choose some repair tools that target the Windows registry.  This area of your computer stores files that the computer uses during every session, and when the computer has trouble accessing files or can’t locate one, you see an error.

If you are having problems with a specific program that you’ve recently removed or updated, it may be that there are some files leftover in your PC that did not get removed during the uninstall function.  Some software manufacturers offer Program Removal Kits that will thoroughly remove their program (or old versions of it) from your PC.  You can also find removal kits that are less program-specific for download online.  Just make sure you are using a trusted site.

The Best Repair Tool for Your PC

If you are having trouble narrowing down what kind of tool to use to improve performance or if you’re still unsatisfied with your computer’s activities after using the above tools, it’s time to add a registry cleaner to your arsenal of repair tools.  Download a registry cleaner as one of your PC repair tools to optimize performance and fix errors all at once.

Fixing Errors Associated With Pogo Back Door Sites

Posted by Kat

We all love playing online games, but all computer users should be aware of the potential issues relating to pogo back door sites.  Some of these pogo back door sites can infect computers with malware or cause registry changes that can damage programs or cause other problems that slow down the computer.

To fix these problems you should first start by running a full scan with your virus and malware protection programs.  These scans are to insure that your computer is not infected with malware or viruses that can cause even more damage.  If you are sure that your computer is free of malware and viruses then you should make sure that your registry was not affected by any of the pogo back door sites.

Registry issues are usually the hardest problems to fix on a computer because there is great risk involved in editing the registry.  There is a built in registry editing tool with Windows, but if you are not sure what each entry does you could damage the computer severely if you delete one that is critical.

If you are not sure how to fix registry issues manually you should always use a trusted registry cleaning program like Regcure.  Regcure can not only clean up damaged or broken registry entries, it can also diagnose problems that are associated with program conflicts.

If you have used pogo back door sites in the past and are now having problems with errors or your computer is running so slow that it takes forever for a program to even open, you should install Regcure today and fix all your registry errors with just a few clicks.  Stop fight annoying errors; install Recure today and get your computer running like it’s supposed to.

A Standard Crapcleaner Program Cannot Get Your Computer Running Better

Posted by Kat

There a misconception that a simple crapcleaner type program can get your computer running faster when all it does is free up space on the hard drive.  A hard drive full of old data can and will cause problems that might slow down the computer, but in many cases common registry errors are usually the main reason many people experience frustration with their slow computer.

A typical crapcleaner will only look at the hard drive to free up wasted space, but Regcure will also analyze the registry to look for errors and to help the processor access data better.  If you are getting tired of your computer running slower and slower each month and you want to get your computer running like it was new again then now is the time to try Regcure.

Because Regcure analyzes the computer’s registry looking for potential problems, it can also diagnose errors and help you fix common program conflicts that a standard crapcleaner program cannot do.  Common registry errors can be caused by many different things that are hard for the individual computer user to diagnose on their own.

Many common registry issues that result in errors are caused when the user starts uninstalling old programs on their hard drive to free up space.  In many cases they will free up space and fill that space with other data, while in the registry the space is still associated with the program that was installed.  The processor might use up valuable resources trying to locate where the data associated with the program went, which can slow some computers down to a crawl.

If you need to free up space on your hard drive and your computer has been running slowly, forget about a standard crapcleaner program and install Regcure today.

Google Adds Encryption to Apps

Posted by Mike

Google has received requests from many individuals to offer a boost in privacy. These requests came from over three dozen security, privacy, and research personnel. Google has deciding that it’s going to oblige to the requests.

Google has always allowed for you to encrypt your Gmail by using https:// however you have to manually set this as the default. Other applications such as Docs or Calendar don’t have this option. This means that the information can be acquired by malicious users. The document was signed by a top security expert and addressed to Eric Schmidt.

Many other sites have this problem as well and users are just as vulnerable to data theft or having their accounts stolen. However Google is able to start a trend in the right direction to fixing the problem.

The problem is that many people don’t understand the risks that are involved in using services that aren’t encrypted. Even though Gmail has the option to do so many people don’t know it exists. If people don’t know it exists then the option itself is basically useless.

Google officials want some time to experiment with putting all of the apps into a security mode so that they will know all of the effects on users’ experience. The biggest problem they’ve found is where users will experience the application slow down when doing certain actions.

Google has announced that it’s going to test the security encryption on a small basis to see what kinds of effects it has on email and other applications. Google plans to make the https:// address standard as long as there are no huge negative effects.

Those who contributed to the letter believe that Google and its engineers can create a low latency system for Gmail and other applications as they have done for AdWords, Health, Voice, and AdSense.

The Need for Security Software

Posted by Mike

Every computer needs some type of security software if the computer is to remain safe. In most cases a computer user can get by with an anti-virus program, an anti-spyware program, and a firewall. However Macs seem to be lacking in security software.

While many people use non-Mac computers there are many people who enjoy the Macs. Many people don’t consider a Mac a PC however since a Mac is a type of personal computer it then would be a type of PC. With all of the people that do use Macs you would think they would have better security measures.

In terms of numbers, the Mac OS X operating system ranks in with 14.3 percent of the most vulnerabilities in 2008. Since there are more non-Mac users you would think that they would lead in the race with vulnerabilities. However, Linux ranks in with 10.9 percent and Windows XP only has 5.5 percent. Thats a huge difference between disclosed vulnerabilities from Windows XP to Mac OS X.

The numbers don’t focus on how big of a problem each vulnerabilty can cause but rather the number of them. This means that Windows vulerabilties could be more critical than the other operating systems we don’t know.

No operating system is perfect however many Mac users under-rate the possibility of an attack happening to them when they don’t realize that they are more vulnerable than many others. If you are a Mac user and you don’t have any type of security software installed then you should tred very lightly as you may be attacked.

This isn’t to say that non-Mac users shouldn’t have any type of security software or that they need it any less. Every person that has a computer should have some type of security software. If you haven’t already you should invest in a security program or two to ensure the saftey of your personal information.

Is Your Online Banking In Danger?

Posted by Mike

Online banking is a tough business. In fact some of the bank’s security systems are jeopardizing information security. We all know that are banking information is supposed to be completely private, and accessing someone else’s information without permission has its own punishments. But how do the banks know when an unauthorized user is getting into your account?

The trick lies with a program that accesses your personal computer’s information as you log in. This program looks at your device information to verify that it is the one that you normally use. It also has a tagging system which marks computers that are thought to be involved with hacking their networks.

This works very well for protecting your account, but there haven’t been any measures taken to insure that the information collected by the banks is being used correctly. These banks could turn around and sell all of your private computer information to advertisers if they wanted. Although no such thing has taken place to my knowledge, there is nothing there to say they can’t. It is even possible that this information could be hacked into and stolen.

If you’re like me, I’m sure you’re concerned about your banking information. Your information should remain secure as long as no one is able to get your personal user ID and password. This is why it is so important that you don’t give away that information to just anyone.

There are other programs that are used by banks that work just like the tagging system, but they work with other information. Some programs are able to determine what language, time zone, Flash ID, browser, cookies, and IP address is being used on the computers you use to access your account. You may be able to see your information on your roommate’s computer, but if you try using a computer across the country it might not work. A percentage of the factors have to add up in this system in order for you to see your banking information. Although this does provide an extra amount of security, it is risking your information in other ways.

Exploits are Everywhere, Even in Common File Types

Posted by Mike

As security advances so does the opposition. Many malicious software makers are starting to notice that the average PC user is becoming smarter when it comes to avoiding emails that could be potentially harmful.

Recently these malicious programmers have started to take a different path. They have begun to create different types of threats. One type that you may have already seen is where the program will inform the user needs to download security software. Three other major programs which are known as Win32/FakeXPA, Win32/FakeSecSen, and Win32/Renos have been found on millions of computers.

Attacks have also been taking place in common files such as .PDF and .DOC. Even Adobe Reader 9 and Acrobat 8 have had several exploits in them. While there are updates out for these programs, many users don’t update their software. For example over 90 percent of attacks in Microsoft Office have been from an exploit that could be fixed with a simple update. Surprisingly this update is over 2 years old!

While many PC users look for updates through Microsoft they rarely look to update other programs. There are a lot of PC users that believe that the Microsoft updates will solve everything. While Microsoft does run the PC business due to most users using Windows, they can’t watch over every company’s individual software issues such as the issue with Adobe.

It’s surprising how many people have issues with malicious software but do nothing to fix it. There are updates for programs coming out all the time to fix these holes and help prevent attacks however many users don’t seem to check for updates as they should. Microsoft alone last year released 78 updates that fixed 155 issues.

Therefore if you are having continuous problems with attacks you should ensure that everything on your computer is up to date. While you may update Windows constantly it’s not enough to stop someone from attacking your computer.

How to Ward Off a Conficker Worm Attack

Posted by Ruel

 

Scared that you might get fooled by a worm on April Fool’s Day?

Security alerts have been blinking since last week, warning users of another strike by a new strain of the Conficker worm on the first day of April. The C-strain is expected to be more resilient than the previous ones, making it hard to detect or remove. An infection will most probably be fatal as it would require you to reformat your hard drive in order to completely eradicate the bug.

While antivirus and anti spyware makers are sounding the alarm, all you need to do in order to avoid being a victim is to be extra vigilant in checking the files that you download, the Web sites that you visit, and the portable storage devices that you attach to your computer via USB or Bluetooth.

Microsoft has already released patches and updates that could ward off a Conficker attack. If your OS is receiving automatic updates from its maker, then chances are is that you’re already protected. Of course, Windows cannot stave off an attack alone. A good and reputable antivirus software would be an excellent (and indispensable) complement to the built-in defenses of your operating system.

Attack of the Bluepill!

Posted by Mike

 

It’s the 21 century and everyone has a computer and many of those people use cable modems or home routers. Recently a worm has been found that can attack various routers and modems. There’re a total of 55 modems and routers that are at risk. Even if you have a top name brand router such as Linksys you could still be at risk.

The codename for the worm is Bluepill or psyb0t. Surprisingly it’s the first of its kind that is actually able to infect home networks. The worm uses a database of over 6,000 usernames and 13,000 passwords to try to get into your network. While this may not seem like much of a threat at first glance, the reality is that it’s a huge threat to your personal privacy. This is because your home network (both the router and the modem) run 24/7. They also allow unlimited chances for you to get the username and password right.

Therefore the worm can run 24/7 until it cracks your system. You may be asleep at the time and not even notice it happening. While this may not seem like much of a threat at first glance, the reality is that it’s a huge threat to your personal privacy. This is because your home network (both the router and the modem) run 24/7. They also allow unlimited chances for you to get the username and password right. If that wasn’t bad enough the worm is designed to execute any code that is programmed into it. Bluepill has been suspected of being in over 100,000 systems. Many users that have their computers infected don’t even know it!

To help avoid getting hacked you should use an advanced username and password that is random and extremely uncommon. If you think that you’ve already been infected then you may want to reset your hardware to get rid of the worm.

Restrict Access to Your Wi-Fi at Home

Posted by Ruel

 

When shopping for a wireless router, the first detail that you’ll most likely look for is its signal strength. Indeed, you wouldn’t want any dead spot ruining your 50-gigabyte download. The good news is many of today’s routers can easily blanket your house with Wi-Fi. They’re already so powerful and efficient that your next door neighbor could effortlessly pick up signals from your overzealous Wi-Fi distributor.

Unless your neighbors are as trustworthy as your dog, sharing wireless Internet with them may not be exactly a wise move. For one thing, having too many computers sipping through your router may slowdown your surfing speed. Some ISPs are also setting limits on monthly bandwidths, so you might end up hitting your quota in just a week if you continue to be a good Samaritan to them.

But the strongest argument against sharing Wi-Fi with neighbors is the possibility of data theft. The fact that they could access your router or wireless Internet means that they could also very possibly access your computer, too.

This doesn’t mean that you should buy routers that have weak signals. If you want to rival Starbuck’s Wi-Fi strength, then by all means buy the best router that your budget allows. Just make sure that you limit the number of persons who could have access to your personal network. You could easily do this by setting up a password for your router. Another method by which you could restrict or regulate access is by pre-defining the hardware which could access your network.
