This seems to be related to a trojan. I had the same prob & a solution issued by TrendMicro works. http://uk.trendmicro-europe.com/enterprise/security_info/ve_detail.php?id=59970&VName=TROJ_SMALL.IP&VSect=T Basically a keylogger is at work. Some registry entries are added and some files written to windows/system32. Remove the registry entries then delete the files. May need a restart.
