I got all the same syptoms and the same solutions worked, (though I still have to get regedit working, only works if i type 'regedit32 at the moment) however, the files it put on my system were c:\program files\outlook\outlook.exe, p.zip and v.tmp. Also, outlook.exe doesn't show high cpu usage in the taskman dialog, but once I deleted it, ctrl-alt-del started running taskmgr again. any thoughts on regedit greatly appreciated.
