(Windows 7 PC) - Have been using Acrobat successfully for about two years. Yesterday, was creating a PDF when BSOD, page fault, occurred. Did a scan with Microsoft Security Essentials and found that several viruses had gotten through - two Java exploits and Trojan:DOS/Alureon.A.
Proceeded with clean-up with MS Security Essentials and with Defender Offline and they claim all viruses have been removed.
Acrobat 9.5.1 continued to get the same BSOD condition - initialize the program, it churns by itself and faults in about 10 seconds or so. Attempted uninstall - failed with BSOD.
Used MS Fixit which identified uninstall issues and 'corrupt patch registry keys' - MS Fixit claimed to fix the uninstall issue but could not fix "corrupt patch registry keys'. Next uninstall attempt failed with installer note "This action is valid only for products that are currently installed".
Next step - renamed Program Files (x86)Adobe/Acrobat folder to get that folder 'out of the way'. Reinstalled Acrobat from original CD - Acrobat 9.0 --- some install alerts flew by but the install seemed to complete successfully and a new Acrobat file was created within the Adobe tree - and several drivers were replaced within Windows. No change in outcome - the installed Acrobat 9.0 thrashes to a page fault BSOD all by itself after initialization.
Attempted to to update 9.0 to 9.1 via the Adobe web site but the installer couldn't find Acrobat - "...program missing or patch may update a different version...." . Ran MS Fixit again with focus on "install" and Fixit identified "corrupt patch registry keys" - and then claimed to have been able to fix that issue but the version update continues to fail with ".... program missing ....".
I am prepared to get Acrobat X Standard to get past these problems if that seems reasonable. It's possible I might have to do a complete OS reload but I'd like to avoid that especially if I get Acrobat X.
I'd appreciate suggestions from the Adobe "pros".
