If you want to get rid of any kind of malware, you should first go to safe mode (tapping F8 during boot proces).

In registry beside HKEY_LOCAL_MACHINE/software/microsoft/windows/current version/run
you should check ...runonce ... runservice ...runserviceonce
and ofcourse all those keys in HKEY_CURENT_USER/... and the same like above.

HijackThis is tool that does all work for you. It check all places from where program or service can run, and also check for some .dll things that spyware drops in IE...
But before you remove anything with HijackThis make backup and consult someone who knows more about this. Like TigerShark said, you can post results here.... it is the best way.

Soda: If you carefully read post from that banned guy, you will see that he (probably) wanted to say that this specific regkey mavax checked is not the only regkey for starting programs
