I just got a virus on my Windows Vista PC, I'm using another PC now. I recognized the behavior immediately within seconds of getting it, basically first some slowdown, then I ran taskmgr, saw that explorer.exe was using about 50% of my resources, instead of the normal number of total used resources being under 5%, and saw a "cfd.exe" that I didn't recognize. I immediately ended that, and it kept popping back up. I ended it each time but it kept coming back. The Task Manager column listed it as some kind of script process, I can't remember exactly what the two words were but the first word was script. Anyway, what happened after a few minutes was that no programs would open. Any program would show a "open with" dialog. While task manager was still working, I closed the explorer.exe process and tried to restart it by clicking "new task..", but when I typed explorer.exe, it said the file/application was not found. So the current behavior is that all programs (windows explorer, notepad, any browser, etc) all pop up an "open with.." dialog, and that when I right click on the taskbar and choose to run Task Manager, it says the file taskmgr.exe is not found. While Windows Explorer was still working and I had it open, in the first few seconds of the time I got the virus, I did what I normally would do in these situations and look through my Temp folder to see what new files, especially new .exe files, have popped up with a recent date modified time. Sure enough, I saw the cfd.exe file and a couple other temp files listed with a created/modified time of 2 minutes earlier, so that file was definitely involved. While my browser was still working I did a search on the cfd exe file and found that it was related to BroadJump Client Foundation, however I can assure you that was not what it was in my case, since I've never had any program like that on my computer and the one I had showed a date and time of just 2 minutes earlier in my Temp folder, so there's no chance it was any kind of legitimate file. I also did some searches on the "open with" problem and found info on some Windows Security 2012 virus, but I really don't think that's what happened, because in the descriptions of that virus, you get something posing as anti-virus software that pops up, and that never happened to me. This all happened in a matter of just a couple minutes. I went into Safe Mode and all the same problems occured, all programs show an "open with" dialog box, and it says taskmgr.exe is not found. So there's really nothing I can do within Windows. I'm not too sure how to fix this.. any ideas? Thanks a lot in advance for any info or help, or any suggestions on where to start.
