Witabett.com None Known Locked up my computer with Trojan warning and worm warnings. Rogue River, Oregon

Was working on my computer when I received warnings all over my computer about being infected with Trojan viruses and worms that was deleting my information. I turned my computer off immediately and then reopened. The warnings were still there and would not let me close their page. After several attempts, I had to order their software to remove the viruses. It said $59.99. Finally I was able to close out of their page and I started to search for a confirmation email for this transaction. There was none. So, I thought that nothing was downloaded. I then had to wait until the next day to view my credit card. The transaction was on my card BUT FOR $79.90. So, I've contacted my credit card to dispute the transaction but without a confirmation email, I can't prove that they over charged me and that I had to order because I couldn't get out of the program. I didn't search for this software, it popped up on my screen and then wouldn't let me out.

I have done a search for this company and have found several complaints listed for this company in a Google Search. They send these popups saying your computer is being eaten up with viruses and they are a complete scam.

I don't know what anyone can do, because if you can't get out of their program when it starts to flash these warnings, and you're forced to purchase their program, they basically have you by the "you know what". You authorize a charge for something you didn't want. And then they change you more than what they said and you don't even get the service.
