They really mangled v. 7 of Virex. I updated and it hasn't worked right since. In my case, I can't authenticate as the administrator of my machine to update the virus definitions.
Another problem was with Fink. Virex creates a new directory at the root level called /sw, wouldn't you know it, Fink does the same. There were a lot of angry Fink users out there when they updated Virex.
