My computer always hangs up now everytime i use the avast antivirus scan. It never did before. What causes avast to hang-up during the scanning process?
How exactly does it hang? A full system freeze, requiring a hard reset, or only the avast! program doesn’t respond anymore?
Are there more info in Windows Events or into avast Log Viewer?
Which is your operational system? Any other antivirus installed in this computer?
