Dealing with worm-infected Yahoo! Messengers in Windows XP is fun. Just apply the fix. Do not reformat because it is the lazy way of fixing things!

If the worm disabled the Registry, Task Manager, and Run command, fire up a command prompt and do the following.
1. To reactivate the Registry
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System
/v DisableRegistryTools /t REG_DWORD /d 0 /f
2. To reactivate the Task Manager
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System
/v DisableTaskMgr /t REG_DWORD /d 0 /f
Search for svchost.exe and delete the macro equivalent. Be careful! Make sure that it is the macro equivalent, not the system file!
