On the machine I can get as far ar the "Control" directory, but that does not have a "MPRServices" directory within it. I assume that this is due to my yesterdays download of the instructions (from Symantec) being applicable to a later version of XP than I am dealing with.
Anyone any suggestions as to what the path to "TestService" might be on the older XP ??
I think its only applicable to XP sp2 and or the latest update from old Bill Gates and co I remember seeing a virus removal tool update. have you tried switching off system restore then run the anti-virus.?
If the key isn't there...it's not corrupted. Are you sure it's not there? Did you use any removal tools that may have deleted the rogue stuff?
In the registry editor look at the tool bar at the top and click on "Edit" then Click on "Find".
Try the various search combinations (use Key first) to look for TestService etc. Try "Control" to make sure you've got the hang of searching through (it should jump to where you've already found the key).
Also search for the virus's "bits":
You may find them somewhere else similar.
Don't forget all the usual warnings about playing with the registry!
