I had a very strange virus one of my PCs that seemed to change the file extensions of certain files (office, pdf, jpg and zip files) and also made the files unreadable when I fixed the extensions and tried to reopen them. We had our IT guy come in and restore a backup, but 2 flash-drives still have the files with this issue.
here is a screenshot of what it does to the files: http://imgur.com/twlkpy5
it seems to capitalize the normal extension, then add ".gpqvsem"
I have run panda security and malwarebytes scans and it doesn't pick up any issues on either of the flash-drives.
Any help fixes the files would be very appreciated.
