Hello I downloaded Avast antivirus upgrade and needless to say it destroyed my computer and for some reason I now have the basic theme and there is no way to change it when I go to my personalize settings. I did a troubleshooting it is says that the mirror
driver doesn't support Aero. I also has had problems in speed. It takes longer to turn on the laptop slowing down at the "Starting Windows" screen and then i'm stuck on the "welcome" screen after I log in. If anyone can help me with either of this problem
please help me.
