hello,
i'm using avg antivirus free and in last few days i noticed that every time i try to scan my computer the process stops at 70% (or somewhere near it). The same happens when i try to update it. The program shuts down and restarts again. I tried to reinstall it but it didn't work either (stops somewhere in the middle of procedure). 
Please help me and thank u in advance
