The aftermath of a trojan attack (Vista Guardian) has resulted in the file
association of exe files being lost and hence an inability to run exe files.
I am quite convinced that the trojan is now dead, but I can't figure out how
to fix the damage.

If I could get into the registry I could fix it, but of course regedit is an
exe file so I can't run it.

I've tried tricks like running it from command line or from inside a batch
file but with no joy.

I have also made a copy and called it regedit.com. This looked promising as
Vista asked for user permission to run the program, but then nothing. It
gets killed off before it starts.

I am not familiar with the particular machine, nor am I very familiar with
Vista and I am now at a loss as to how to proceed. Any bright ideas?



many thanks
