Hi,
Don't know what's happened to 4.5.512 beta. When right-click on the blue ball (a) and choose " Stop on-access protection " to stop the on-access protection but when I want to re-enable the on-access protection again, it's failed. When trying to right-click on the blue ball, no menu appears or it takes to much time to appear but almost fail to open right-click menu. I have to use avast! External Control (thanks RejZoR) to re-enable on-access protection again.
My system
Pentium-M Centrino 1.3 GHz
256 MB of RAM
Windows XP Pro XP1
Thanks.
