NIS 2010 versus MSA.exe

A week ago my girlfriend downloaded a codec pack because she tried to play a video that told her to open it in Windows Media Player (which of course opened an IE window to some site that installed some malware on my computer).  That installed a temporary file called b.exe or b.(some extension), and my computer started acting slow and not working properly.

 

I tried to run spybot, but apparently i had no privledges, which doesn make sense and has never happened before.  I figured it had been corrupted, so i uninstalled it.  I selected the option to uninstall it completely, restarted my computer, and i was still getting messages from it telling me b.(extension) was trying to update the registry. 

 

I uninstalled it again and restarted my computer, only for the next 8 times i tried windows wouldnt even start.  It would get to my desktop and immediately say "Windows has found an error and will restart now".  It was not until i had restarted so many times that Windows had to open in repair mode that i actually got windows to open succesfully.

 

Even after i got rid of the b file, i still have something called msa.exe on my computer and it runs on startup.  I couldnt even find the process in msconfig to tell it not to run on start.  To my understand, msa.exe is a version of msAntivirus, though none of the fixes i found for that seem to apply in my case.

 

At this point i decided to get NIS 2010.  It was obvious that i had a virus, so i spent the money, installed it, and immediately tried to run a complete can.  The complete scan found some tracker cookies and even found (and supposedly removed) msa.exe, but about half way through the scan it crashed.  After that point i couldnt open it at all.  I tried uninstalling it, then running it again and the same thing happened. 

 

Now whenever i try to open it im taken straight to Norton One Click Support, which repeatedly throws the error "hsie2010.exe has stopped working" about 10 times, then it crashed.  When i try to scan a folder by right clicking on it and selecting scan, a process is created but it never seems to be doing any work.  I cant even scan from the command prompt.

 

Does anyone have any idea what i need to do to get red of this problem?  At this point NIS is getting abused by msa (or whatever else it is).

 

Thanks
