can anybody help me please?

hi there...i have this problem with my computer. i have experience a virus called "aikelyu". i already know how to kill this virus so there's no problem. but when i clear the traces of it, i was able to edit the wrong file in the "regedit".
i went to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogonand then wrongly changed the C:\WINDOWS\...32/userinit...exe, i can't remember exactly. i was able to change the last part which is "userinit..exe," into "explorer exe". now my problem is when i restart the computer i can't log-in anymore. It will just say "loading personal settings but after a few seconds it will automatically log-ff. i can't log-in to my account. can anybody lend me some help here please? how do i go about this? please i badly needed your help. i have some common knowledge about computers but that's not enough. i already tried some safemode menu but my administrator account still cannot get in it will still log-off automaticaly. any troubleshooting instructions you can give please? thanks

thanks for your quick response i really needed a troubleshooting instructions. i'll wait for you then...

ok i'll do that. i'm in a cafe right now coz i really can't access my computer. aside from that is there any other ways to get in? i would welcome additional ideas just in case i needed a back-up plan. thanks for your help.
