Winfixer is indeed the worst pain I've ever experienced. Spent hours on it.
Parenthetically, the Symantec tools, FixVundo.exe and FxVMonde.exe did not
remove it (downloaded in late December, 05).
I was lucky though that I finally found this page while searching from a
friend's computer:
http://www.bleepingcomputer.com/for...janVundoB-Search42com-MSevents-tx18610-0.html
In my case, running virtumundobegone.exe (see Removal step 2) in safe mode
got rid of it, and I did not have to work through the rest of the steps.
One quirk. Winfixer prevented explorer.exe from running in safe mode, so I
could not double click the .exe file to run it. Here's a workaround: I had
downloaded the tools referenced in the above page to a floppy and was able to
copy them from the floppy to a folder I created under C:\ named Winfixer, so
the path to the file was C:\Winfixer\virtumundobegone.exe. In safe mode,
press and hold ctrl and alt, then tap del. That will bring up Task Manager
(for the gurus here, if I started explorer.exe this way, it would immediately
crash). In Task Manger, click File, then New Task. Then Browse to
C:\Winfixer\virtumundobegone.exe and click OK.
It took only about 2 seconds to "fix" Winfixer. I then booted to normal
mode and have been fine since. After the reboot, you'll find a text file on
the desktop that shows a log of what steps virtumundobegone performed.
