Most definitely, contact your credit card company and dispute the charges, stating the program is a "scam". Most likely, the customer service rep will have some knowledge of this already.
The Antivirus System family of programs are what could be termed "ransomware". Your pest works like this ... it runs a faked scan that displays bogus "infections" that it won't "remove" until you purchase the product. It has a built-in protection device that terminates real security programs before they can eliminate the threats. It can also change the proxy settings in your Internet Explorer to prevent you from viewing any sites that Antivirus Elite doesn't want you to go to (which is pretty much every other side out there). So, the bottom line is, this pest ransoms your computer until you buy the program ... OR you do as you are doing here, and get help in removing it. The good news is that we should be able to eradicate it and get your computer running normally again.
Please allow me to reinforce something Corrine has already mentioned ... at this point, only get help from one computer forum. Well-intentioned people may have you do something else at another site that we don't know about, and your computer could end up being an expensive paperweight. "Too many cooks" is the expression that comes to mind.
