I have Avast! home edition, and it is working fine. but the problem is that when I go to the windows security center it says that windows doesn't finf any Anti-virus on my computer
I'm not that stuped, please read my post I said that this happened to me today. I have used Avast! antivirus for about a year, and windows was able to find my anti-virus.
yes it is updated and I have reinstalled my Avast! antivirus and i still have this problem.
Also, when Avast! is not updated it will say to you that your antivirus is not updated, but it doesn't say to you that it can't find any antivirus on your computer.
