Computer virus corrupted all document files

[gvstn]

3. Sorry, I haven't had time to look into this further.

Since there was no ransom notice and the names of the files including extensions have not changed that gives us no clues. The files do seem to be acting as if they have been encrypted. The RTF particularly. The question is why would a virus randomly encrypt files? I haven't found a thread with any solutions.

This Kaspersky tool is specific to getting encryption keys for files locked by specific known viruses but explains in the description how file names are usually changed thus identifying the virus. http://support.kaspersky.com/us/viruses/disinfection/8547 It won't work on a random infection.

This thread is where I have gotten it in my head that you may be victim to encryption even without ransom. You might read through it and see if your files act as described. http://www.symantec.com/connect/forums/some-virus-has-corrupted-many-our-microsoft-office-files-and-pdf-files

I'm going to do some more reading tomorrow on the original error message and see if I can find other possible causes or solutions. But first look doesn't seem too promising for an easy fix.
