Thanks for the tool but i used another way.Services.exe was infected on the customer PC.Replaced it and now system is clean.
Appreciate your help
From what I have seen, Services.exe is not infected but has the Sirefef file system from C:\Windows\Installer\{GUID} loaded into it. After correcting the CLSIDs and rebooting, sometimes Services.exe is still loading the Sirefef filesystem. Killing Services.exe, safe mode seems to be most effective, and then deleting the C:\Windows\Installer\{GUID} should solve your issue. Process explorer can kill Services.exe but be aware that the computer will reboot shortly there after.
Although if there is a variant which does truly infect the Services.exe and someone has a sample they can post, it would be most appreciated.
