PLEASE HELP!!! Somehow my computer (Win 7, 64 bit) has been infected with DirtyDefrag.exe virus and in spite of running a full scan with Panda it did not trace it. I also have installed Microsoft Security Essentials and AVG but neither of them is able to pick the crap up. When I try to open my photos, MS office, PDF files and videos, all are encrypted. Meanwhile, a message comes up, saying “File is encrypted. This file can be decrypted using the program DirtyDecrypt.exe”. Any suggestion or help would be greatly appreciated. Thanks heaps.
