I am working on a Windows 7 Pro x64 workstation. Core I7, 1TB HD, 8Gb RAM
In the root directory only, all *.exe files have been changed to *.LNKxxxxxx, where the "x"'s are a random combination of 5 or 6 letters and numbers, and are different on every file. For example, one file is "MicrosoftWord.LNKso569" and another "MicrosoftExcel.LNKh3z376".
Some files are *.exe.LNKxxxxxx, and others do not include the ".exe"
*.exe's, nor any other file type, have been affected in any folders, including user or program folders.
I should note that this computer is part of a network that just got hit with the AMNESIA ransomware, which we are remediating on the server (emsisoft decryptor). None of the workstations were affected by the ransomware, but I found this issue during my investigative process. This is the only computer experiencing this file name issue.
From a clean machine, so far I have run Norton, Malwarebytes, and SuperAntispyware on the drive and all have found nothing.
Several google searches have also yielded zero results of anyone having this problem. It is not a standard file association issue, since it is relegated only to exe's located directly in the root directory on the c:drive.
