i am using avast! 2013 free antivirus .My program version is 7.0.1474. I am also using windows 8 pro.
The problem is that as long as the avast shield controls are on, i cannot open settings of windows, as soon as i click on "change pc settings",it opens for a second and then crashes back to the start screen but when i disable the shield control, everything works normally.
I rely only on avast and don't want to change my antivirus ,so please give me suggestion about the problem.
