How to scan virus on computerThere are few steps to scan and remove virus from computer and should apply to any Windows operating system.

  1. Proper scanning a computer for viruses and other malware could take several minutes or longer. So close all unnecessary programs since scanning will take lot of CPU and hard drive time and by closing any programs that use CPU resources will make the scan run faster.
  2. Open your antivirus program and schedule the automatic update to run before the virus scan. It’s important that the update is run automatically in addition to scans. If updates are not run automatically, they can easily be forgotten. Check your computer at the time the scan was scheduled to begin to ensure that it runs. Schedule the scan to run at a time when you’re around to verify it. However, don’t schedule for a time when you have to work. The scan can dramatically slow your computer.
  3. Before running a virus scan or malware scan on computer, you need to make sure the virus definitions are up to date. These regular updates tell your anti-virus software how to find and remove the latest viruses from your PC.
  4. Virus Scan can be done through all incoming email attachments. Be sure to run each attachment you plan to open through the anti-virus check though sent by trusted person. Be sure your email program doesn’t automatically download attachments. Refer to your email program’s safety options or preferences menu for instructions. There are on-line email services, such as Hotmail, automatically scan each attachment before you download it.
  5. Update your anti-virus software frequently. An antivirus software program is only as good as the frequency with which it is updated. New viruses, worms, and Trojan horses are born daily, and variations of them can slip by software that is not current.
  6. Data CDs are one of the most common ways viruses are transmitted. If you are using a data CD while working on your computer, remove it when you shut the machine off or the computer may automatically try to boot from the disc, perhaps launching or installing bad programs or files on your computer. Even don’t share data CDs.
  7. Full system virus scans should be run regularly in a week and partial scans should be run more frequently. It is also recommended that you install a firewall that will run alongside your virus scanner, which stops intrusions into your system unless you give permission. There is a lot of virus scanning and firewall software available for home users at affordable prices.
  8. Scan files for viruses before using them on computer. If you are using a disc or flash memory to carry information between one computer and another you can get easily pick up a virus from a corrupted file and introduce it into your computer. Running a virus scan before launching any of new files will prevent infection.
  9. If you are not sure about an attachment you received immediately delete it without opening or downloading. And if there are tempting animations on a site that look highly unprofessional, don’t download them.
  10. Install reliable antivirus software as they scans files regularly for unusual changes in file size, programs that match the software’s database of known viruses, suspicious email attachments, and other warning signs.

Make sure any virus scan includes the master boot record, boot sector, and any applications currently running in memory. These are particularly sensitive areas of your computer that can harbor the most dangerous malware.
