REALGOLDSOFT Securekey Antivirus Infiltrated my computer and said I had viruses and spyware Internet

A company called securekey infiltrated my computer and did a complete scan and said that I had over 723 computer security issues from viruses to spyware.  Offered a program called secure key for a price of $49.  Purchased the product to find out the product is a high level virus to get people to submit thier credit card information.  Said they would send me an email on how to download the product.  Never recieved it.  Just a confirmation that payment was recieved.  Called my credit card company and they said there was an authorization for $99.90 for a company called Goldsoft.  Called the company back and asked for a refund.  They said they would issue a refund in 5-7 days. Still can't find the product that I supposedly purchased.  Bad thing is my credit card company will not let me stop the charge.  They say I have to print a copy and fax it to thier dispute center to get anything done about it.  Or wait for the bill and highlight the charge and dispute it that way.
