I have a Dell with XP sp3 office computer need it back up and running by tomorrow.
I had the xpantispyware2010 infection, and removed it in safemode.
When i return to the operators profile all the file associations are gone and all programs ask what programs to open with. .doc .exe but also msconfig, install/uninstall programs etc.
Now other profiles everything works just fine its just the main operators profile (which of course was the one infected) need a way to fix the associations on the operators profile asap.
