Few minutes ago, my dad was surfing on Ebay when he got a virus from KAV that shows they detected a Trojan named Trojan-Spy.HTML.Fraud.gen. He deleted the file which was a IE temp file. After that, the same alert about the same trojan pops out again and keeps doing this until he deletes the cache. After that, the virus warning pop-outs stop. Is this a false positive by KAV or what? Again, this happen only a few minutes ago and not in reset of day.
