NIS 2011 crash with new Foxit PDF viewer

I updated my copy of foxit to 5.1 last night and as soon as I installed the new version it crashed NIS2011, in windows xp pro. I did all of the scans and it found nothing but scared the hell out of me. because all the norton services in task manger just disapreed and no error message was to be at hand. Up on reboot it was like nothing ever happened.

 

anyone else have this problem? or would like to try installing the new foxit PDF viewer 5.1.

 

I've also ran Malwarebytes' Anti-Malware,SUPERAntiSpyware Free Edition. also uploaded it to virustotal, clean bill of heath.


I tested it again today and it does the same thing up on installing.strange.

 

I should add, that the program it's self works fine once you have it installed and reboot but that first install is a buggy one.
