[comp.virus] Virus scanning on PCs?

  Do scanning programs (in particular scanv45) check video memory for a
virus? I once developed a program which installed itself in the 2nd page
of video memory because there was nowhere else for it. Not a virus, just
a fix for some BIOS bugs, but someone else could hide a virus there if
they were so inclined. Very little software ever uses any page but the
first.

  Oh, if the video pages were swapped and then output to the serial port
was done, the display was really pretty!
