Hy there... I have the same problem... I had install imesh soft and inmidiatly after... a lot of crap got installed on my pc.. including defender, newdotnet (spyware), gator (advertising spyware program), Bonzi body, etc... and of course... the famouse H@tKeysH@@k.DLL trojan (acording to defender soft).
I have no doubt that this trojan is not such a thing and it's copied by the defender...
You should try to move the file to another folder to see what happens.. (I'm sure nothing) or you can change the extension of the file to avoid anyone to use it..
If you can't delete this garbage file, you should start with DOS and delete it manualy (del c:\windows\H@tKeysH@@k.DLL or del c:\windows\H@tKey~1.DLL) and it will be deleted I assure you...
About you Darril, I think you are a lyer and you are part of that shi!@$# soft, so please at list be a little bit smarter and make a better performance in your play.... loser!...
Hope every one understood that this is not more than a file that the defender program puts in your pc to show you that it can detect a virus that the others can't, but it is not a virus, it's a hoax...
Defender sucks!!!
