Help. I seek an AV that runs on XP. I want it to run on-demand only (right-click usage) - to be used as a 2nd opinion. (Yes, I am cognizantly cognizant of the factual fact that I could use Hitman for this porpoise, but me no likee dot ting....) Just let me know what might *easily* run on-demand only. Please avoid qualitative comparisons or the Mods might succumb to a state of jawful tightfulness.
