REALGOLDSOFT BAKU Notified me my virus software was overdue and said someone was trying to get my credit card number, Internet

In November while working online, I had a pop-up message that my virus protection software was overdue and that I had a virus and that someone was attempting to access my credit card numbers.  I went into the purchase options and I had a choice of 1 year for $49.99 and 2 years for $79.99 -  I chose the 2 year option.  I was told I would get an e-mail receipt immediately after I purchased the software.  I did not receive an e-mail receipt.  I just received my December-January statment for my Visa card and found that a company called  RealGoldSoft Baku had charged my account $99.85.  I went online to see what product this company represented and found a number of customer complaints of internet fraud for false sale of virus protection software with stories very similar to mine,  I have notified my Visa card company and am contesting the charge.  If anyone knows where this company is located, I would like to file a charge against them with the Better Businnes Bureau of their region........Kathy, Paoli, PA
