I installed avast! 7 few days ago and it was working without any error. But today suddenly when I start windows (XP) I had no sound on my PC and avast service not started. I checked sound driver via Device Manager but there was no visible error. But when I check Sound and Audio Devices option at Control Panel, all the options were inaccessible. Then I did try repairing avast few times. But no point of repairing. At last I just uninstalled avast and now everything seems OK.
Should I install avast again and see what's happening? Do you guys got any solution or tip to follow before installing avast or after installing avast 7?
And another thing. Don't know it is related to this matter. I had Google Talk application installed on my PC and now it says my account is locked. Can't sign in with old username and password.
