Hey Guys.
I have been trying all of this stuff to get rid of my problem which was, a fake system error saying I was infected with Trojan-spy.win32@mx.
In the end I just went to C/programfiles and found a file in a folder called Videocompressioncodec that contained the file "pmsngr.exe"
It would not let me delete it so I booted in Safe Mode and got rid of it and deleted all instances in my regedit and bingo...messages gone and computer back to normal.
I did use CleanUP and Ad Aware and in the process of removing old files and spy ware I freed up 5GBs of space.
Thanks to all.
Some of my comments.
I had problems downloading AVG but have heard a lot of mixed reviews so I kept my norton as I have not had problems till this. (Norton will not be able to get rid of it)
CleanUP is great and I reccomend it.
Ad Aware is free and the most downloaded one I could find and it is great too.
