Using UNLOCKER ASSISTANT I was able to erase XRG.EXE (located Local Settings\Application Data\). After that the system acted crazy. Via a network connection I loaded and installed my copy of SAS professional but it kept crashing partway through. I then downloaded SAS Free and installed it. It ran and removed about 1800 dangerous files. I was then able to run SAS Professional which found and removes another 600+ files. The system is no longer crazy and all seems to be normal again.
