Personally, I want my AV to catch whatever virus for whatever OS/platform there is.
No need for *me* to be sending a virus to *you* because my AV didn't catch it - no matter what OS *I* or *YOU* use, ya know?
Whatever AV y'all use, turn it up past Default! Do us ALL a favor and kill as many POS viruses as you can! Even if they are for some obscure OS... KILL 'EM! KILL 'EM ALL!
I'm doing my part, KAV is Full ON here.
