"Antivirus 2009" spyware problem

On Saturday I went to fix a computer that had this "antivirus 2009" problem.

This program would say that the computer had a spyware infection, then it would launch another program and then it would repeat.

During this time, the program that I needed to run would not run but the process itself was taking the CPU resources up to 99%. I had no choice but to terminate the process to get the computer working properly until I found a way to get rid of this troublesome "antivirus 2009" program.

I tried using Spysweeper and HijackThis to get rid of this program but I was not successful.

Eventually, I found the solution to this problem on this forum post:

This experience has made me aware of the fact that this "Malwarebytes' Anti-Malware" program is worth taking a look at to get rid of spyware.
