I posted the following
"I am running a Windows 7 Pro 64 PC that houses files for multiple users. The windows and other programs seem to be running ok but today found the data had an extra extension applied to the file name. the extension is .ltugtqe after the full name. This appears on all data file such as jpg, pdf, doc etc... So the file name appears as picture.jpg.ltugtqe and listed as ltugtqe file in the file description. If the file extension is removed the file still will not open. I have scanned for both viruses and malware with none found. Any ideas or suggestions appreciated"
the response is informative but would like to add a little more. Was wondering if anyone has seen that file? I receive no notice or demands for ransom. no indication of an issue other than the file extension.
