Hello, 2 days ago i installed windows 7 and then avast chrome and reader etc but today when i turned on the pc , i found that avast and another software were uninstalled and reader and chrome were there and also desktop icon's size was changed and audio driver (which i installed automatically online with windows) was also gone, can some one tell me what could be the reason and how to avoid it in future? thanks
