My system: avast! 4.1.418 italian edition, Windows XP sp2 (but I had this same problem before sp2), Outlook Espress 6. I also use a router adsl u.s.robotics and zone alarm firewall, but I'm sure they don't give any problems.
I've installed,repaired,unistalled and installed again avast! bat the problem there is always. I think, first problem should be that I don't have the file called ashMaiSv.exe running in background... Could you help me, please?
