well if u deleted the worm manually from winlogon.exe btw winlogon.exe is a windows file, it should be under here C:\WINDOWS\system32\winlogon.exe if u find it else where its junk but if u deleted the one thats in there (which i doubt u can erase, it won't allow u and even if u delete it u will get errors..) so get a anti-virus program & spyware program, update their definitions and scan. also immunize your system so that u don't get junk stuff again..
