Steps to diagnose a computer virus

If you have any of the symptoms above and want to find out if you are indeed infected with a computer virus, follow these steps.

  1. Go to the Bitdefender Quickscan online site
  2. Click on the “Start Scanner” button
  3. Select “Scan now”
















We do not recommend Bitdefender products here. However, the reason we are recommending it for the purpose of diagnosing your computer is that it is one of the few online computer virus scanners that do not require you download anything.  It wills can your computer completely online. Most modern computer viruses would lock files form being downloaded and thus, prevent the scanner from working.

If you find out you do have a computer virus, its best to contact a computer virus specialist. Modern viruses can be very nasty and damaging to remove. h
