Just found the same crap in my documents. I just had to defeat some adware today as it slipped past AVG, Ad-Aware, and Spybot S&D. Had "Call Dale.exe" & "mail bags.exe". Must be very new crapola.
Just as windows begins to load, (before Windows with moving color bar) press F8, choose safe mode and boot on up.
Open explorer, go to your documents, probably thru documents and settings folder. Click once on file, the hold down SHIFT and press delete key. It will be gone forever. I just did this 15 minutes ago, all is working well.
Also click start, run, type in MSCONFIG, press enter. Look for strange entries. mail bags was in folder "funk up system" or
something like that, stashed under the "application data" folder.
I started getting popup windows, that is what made me start searching. My system has been free of popups for over 2 years.
Good luck.
