It's a file in TrojanHunter...completely harmless and can be easily removed. (Try deleting the file before opening internet explorer at all)
redundant after deleting of "Uneraser" utility
I think this is a file from the soft of Msnshell
comes from unerase, to delete it, first go to program files then look for Disketernals, highlight that folder then MOVE TO DESKTOP, then start in safe mode and delete and empty recycle bin. bingo its gone
