Since I installed NOD32 on my computer I keep getting alerts about win32/tenga.gen virus . AMON deletes the infected files and it destroys my system, I can't log on after restart. I formatted my HD and reinstalled everything, but that virus keeps coming back. Back when I had Norton Internet Security, it never found any vruses like that, but then I replaced it with Kerio Personal Firewall and NOD32. That's when the whole mess started. Plus I get Windows Security Alert that my antivirus definitions are out of date, though NOD32 updates itself every hour.
