Hi, my computer became infected recently. Others were able to type on my screen using a remote machine and I couldn't log into my PC unless an internet connection was active -- the screen just went black after I entered my password otherwise. I discovered that my winlogon.exe file was dated 1/15/2011 and the MD5 didn't check out, though the size was correct. When I reinstalled windows, it was still dated 01/15/2011. So I reinstalled from the DVD and installed all available windows updates and the timestamp was then 10/28/2009. I'm running Windows 7. I looked around on the internet for a place to report this file and, amazingly, didn't find one. I really don't want anyone else falling victim to this. Does anyone know who I should notify about this so virus scanners begin including this file's signature?
