Thank you all for your suggestions I do realize I can get them from anywhere, but my husband keeps saying "Where are you when you get the virus detected message?" and I say "the FORT, of course!" One time he even asked me which porn sight I was on, because apparently that is where it came from. :rolleyes (and I wasn't on one, I swear )
So anyway, we will definately be looking into other stuff to safeguard our computers. Meanwhile, keep up the great advice everyone!
