It appears that in the past week, my system has become infected and now continuously retarts explorer and limits all administrative rights. I have come up in safe mode and checked for newly added programs, run spyware doctor, adjusted DEP, but have had no luck in stemming the problem. Except in safe mode, i can not copy files or run any admin tools. Unfortunately, we do not have a current backup, so wiping the drive is not a good option at this point. I have read many forums, but there does not seem to be any consensus on this problem or a solution. Any help out there? I run with 2 users with admin rights and one id without. Have noticed 'tpfnf7sp' open as a process, in looking at task manager.
