Computer Toubles

So for almost more than a month now I have had a virus in my computer. I must say that it is a first for me. But now I have officially been initiated into the world of technology $75.00 later.
I got a pop-up that resembled a spyware that was offered throught microsoft. It askes you if you want to download this program. Looking like microsoft I went for it. Well it started to download, and that was it. A virus had planted itself in my computer.
Turns out that someone started this just to get your money. It all begins with a download then it gets into your system and it constantly askes you to register this program and then sends you to a webpage to buy thier anti-virus system to fight against viruses that they planted.
But that is not all. When you try to uninstall the program it finds somewhere else to spread to. Each time you do this it spreads more and more.
So anyone who reads this, DO NOT DOWNLOAD a program that looks like mirosoft Shield of red, blue, green and yellow. It's a VIRUS!
