I have 3 pc’s all of which are running xp pro and the newest edition of IE. On 2 of my pc’s, I can open a normal browser window, with avast running. If I have avast running on the 3rd pc, the browser window will open, say it is downloading and then will say done and the screen will be blank. If I turn off avast, close the browser and then restart the browser, it will open normally. I have tried uninstalling and reinstalling the newest version of avast, but it still does the same thing. Please advise, because the pc is worthless, if I can’t use the anti-virus.
Any firewall in this third computer? Other security program?
Did these computers have Norton installed before avast? Any other antivirus?
Did you fully scanned the computer with avast?
