The poster never identified the pest but appears to have used anti-parasite tools to kill it off.
unable to find anything on forums re this problem, but i experienced same prob on win2k pc after installing mcafee 7.1 - pc had lot of spyware which cleaned straightaway with adaware. cleaned and seemed to be ok until after reboot when system hung after loading profile.
just stopping process from task manager, just seemed to restart. ended process tree and was able ro log bk in. needed to search for this wihtin registry and deleted all refernces to this item and exe file which was within C:\winnt\system32 - pc boots fine now.
i would love to know more about this executable from anyone else that has had this....
