spyware? microbillsys - mbslgn32.dll, msbmon32.exe, msbreg32.exe

[neurotran]

Greetings

It has been over 10 months since I took the advice given in this forum, installed SBS&D and switched to Fx. Since then, touch wood, not a peek from any undesirable software. Many thanks to everybody who contributes.

This is not a problem with my machine. A friend had this nuisance in his machine, running Win2000. A frameless IE window opens shortly after he connects to internet, impossible to minimize or close, also constantly stealing focus so there is no way to see any other programs. He is told he owes money and asked a payment for a service he says he did not knowingly subscribed. Window also states that it will stay there until he pays. The window is making a connection to the microbillsys.com, which seems a legitimate company, but the running program is straight out of hell. No un-installation facility, killing with task manager is pointless as it launches again. Several emails he sent to microbillsys went unanswered.

I run a scan with S&D (and some others), latest definitions, but nothing was found. I pinpointed the problem to three files in winnt/system32/ folder:

mbslgn32.dll
mbsmon32.exe
mbsreg32.exe

which I have copies. Before I go ahead and delete them at startup I wanted to get your much valued advice as I can not find a mention of these in any where on web. Thanks.
