Does your computer suddenly slow down?

 Have you ever thought that your slow computer may be infected by some unknown viruses? I had been experiencing an extremely slow computer for some time. I would like to share my experience about how to remove viruses and trojans with you.

It is sure that most people install an antivirus software in their computers. When they are experiencing slow computer performance, they would tend to ignore a possibility that their computer might be infected by viruses or invaded by Trojan since they have installed an antivirus program.

As long as your computer slows down, give a thought to removing virus and spyware. You can follow the steps to check and remove suspicious files manually.

1. Remove the registry entries hidden by Trojan or viruses

Once you find some programs on your PC run abnormally, you should immediately check the following entries in the Registry, and directly delete the spyware-related registry entries.

HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServicesOnce

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

2. It is probably a way to load malicious program, by hiding within the system WIN.INI file and the strings "run=" and "load=", so this must be carefully checked.

3. Clean up IE Temporary file folder where the original carrier of PC threats is possibly stored. Meanwhile, the malicious files generated by Trojan and viruses are possibly located in the following Location:

C:Program Files

C:WINDOWSsystem32

C:Documents and Settings All Users Application Data

Removing viruses and Trojans manually is not a simple job. So it is not the best way, especially for a new computer user. I suggestion that you install another antivirus program to give your computer a full scan when your computer suddenly become slow and your antivirus program does not identify any virus or Trojans. Pay attention that you install one that is compatible with your original one. Most antispyware or antivirus software on the market can not go along with other antispyware or antivirus software.

But Best Spyware Scanner, as I know, is compatible with various antivirus software.
