Missing memory virus detector

SearchSecurity member Jeff Kirby submitted this tip for determining whether or not your system has a virus.

This tip was submitted to the searchSecurity Tip Exchange Contest by user Jeff Kirby. Let other users know how useful it is by rating the tip below.

Not sure if you have the latest virus signature updates and think you have a virus that your antivirus software just can't cope with?

Try using the memory test. Start your computer in DOS mode (better than opening a DOS window in Windows), log on to the root directory, C: usually, type in MEM and press enter.

If the base memory is less than 640K, then you either have a real issue with your system, or -- chances are -- you do have that virus that your software cannot detect.
