AVG Anti-Virus Paid Program Does not do what is guaranteed , Internet

Is AVG Anti-Virus a scam?  In my opinion it is.  I used it for several years.  However, in October 2009 several virus got pass the program and infected my computer even though the program ran all the time that my computer was turned on.  After about 5 days the AVG people contacted me by phone and controlled my computer by remote to remove the virus since I was having troubles removing the viruses prior to them controlling my computer by remote.
Because of this I then made the mistake of buying AVG Anti-Virus for 2 years.  Then in May 2010, mind you less than 1 year, my computer once again was infected.  This time with 61 infections.  I know this because I was manually able to use the AVG Anti-Virus program.
It took me about 2 hours to get the computer up so that I could run the AVG Anti-Virus program.  It ran from 12:15AM to 4:00PM (yes, that is right - over 15 hours!).
At that time, the computer went down fully and I could not get it back up.  Thus, I was forced to go out and buy a new computer.  The computer came with programs including an anti-virus program.
I then sent an email to AVG to get a refund for the 2nd year (mind you the second year had NOT yet begun!).  Of course, AVG refused.  They expected me to email them, which I could not because my computer was out completely!
I will never spend any money to buy an AVG product again.  As far as I'm concerned, their AVG Anti-Virus program is junk since it does NOT do what it says it will do.  If at all possible, stay way from the AVG Anti-Virus program!!!
