When I open a PDF it can be an old one a new one no matter what it just slowly zooms in. I have no control over this. I cant zoom out or use any of the file menu items I cant even close the program I have to crash it out with task manager. I have uninstalled reader downloaded a new version. Virus scanned, adawred, spybot scanned but its still the same. I cant help but feel its a virus of sorts but AVG doest pick it up. Any help would be great. Thanks in advance.
