Can't install Norton, still have virus after Norton "supposedly" cleaned it out!!

Okay so I get a virus that popped up with AVG antivirus.   It was a Win32 Heur and Vitro.  So I figured I would buy Norton run the scan, fix the problem and get some tech support.  So I pay for the program, can't install it.  I try over and over again.  I get onto the web chat with the analyst.  He does a remote desktop and tries to install himself, nothing.  So he puts me to the Virus removal techs.  They get one, I Pay $100 for them to take care of the problem.  Took 6 hours, and I still have the same problem.  They gave me a 7 day period so they will work on it again for nothing from what I understand!!  

 

Any I guess what I'm trying to get at is I did some research on this virus and read that I am pretty much going to have to reformat my hard drive!! But I read that that may not even fix the problem!!

 

If I have to reformat I would like a full refund!! B/c technically I have done it before and I wouldn't have dropped $100 for help and $50 for Norton Antivirus.  

 

Any advice here etc would be great!! Thanks

 

I will be on again tonight trying to deal with the problem!!
