You could try this one also:
Removing Autostart Entries from the Registry
Removing autostart entries from the registry prevents the malware from executing during startup.
Open Registry Editor. To do this, click Start>Run, type Regedit, then press Enter.
In the left panel, double-click the following:
HKEY_LOCAL_MACHINE>Software>Microsoft>
Windows>CurrentVersion>Run
In the right panel, locate and delete the entry:
Service Manager = "%System%\SERVICEMGR.EXE"
Close Registry Editor.
NOTE: If you were not able to terminate the malware process from memory as described in the previous procedure, restart your system.
Hope that helps,
