i have a couple of problems - first is my main toolbar including start menu etc is frozen and gives the Windows "dung" sound when i click on it. This means i cant access control panel to uninstall programs. Secondly, i have downloaded avast antivirus, and it thinks everything is a virus! Its stopped me watching videos on VLC media player, and even wont let me get into task manager! I found an answer on here relating to my first problem, but now i cant get into task manager i cant try and solve it, and becasue i cant uninstall avast because of the first problem! Nightmare! can anyone shed some light please?
