I recently scanned my system with TrendMicro's HouseCall, and it found malware.Bkdr_Ircflood.X running in memory (and cleaned it). It never found any files that were infected with the virus, just said it was running in memory. I decided to format (it was time to format anyway), and after installing Windows XP and mirc 6.14 (did the same with 6.12), HouseCall found it again.
I was wondering if this was a HouseCall bug or if anyone else had this problem?
