If Your PC is Running Slow, Run a Scan Using Up-to
If your PC begins behaving sluggishly or programs start inexplicably failing, or you see items in your email "Sent" folder you didn't send, it's very likely that your computer has a virus. Most computer viruses are multi-headed monsters that can embed themselves deep within your PC in ways that are very difficult to remove. If you think you have a virus, the first step is to do a full system scan using an anti-virus software like McAfee Internet Security. In addition, you should take the following precautions:
Immediately disconnect your PC from the Internet or Intranet by unplugging the network cable. This will prevent the virus from using your computer to steal your private information or infect other computers.
Back up your documents, pictures, and other personal data to a CD or DVD. Do not back up applications because they may also have been infected by the virus. A regular backup of your important data files should be part of your normal routine to avoid any data loss.
When using an anti-virus program, be sure you have the most recent version of the software to get the best chance for eradicating the virus.
Reboot your computer after running the anti-virus software and scan it again to detect any lingering viruses.
If the anti-virus software is unable to remove the virus or the problem returns, you may need to reformat the hard disk and reinstall the operating system and applications from the original disks.
Most people get viruses because they are not running up-to-date anti-virus software. The best way to prevent problems in the future is to update your anti-virus software annually and to set the program to automatically download new definitions as they become available.
