Yes, you have been victim of a scam. Do not ever download or buy a software just because a website said so. That websites are known to scam people and to install viruses in your computer.

Thank you very much. I really appreciate your reply.

Now, did that company infected your computer? and how did you remove the virus/bad program"  ? I think it said the program was called EFE.exe during the "installation", but my MS search failed to find that in my C/

I couldn't access the solution. Could you please send it to me? Thank you in advance. :o)

I have this problem now. The shield looks like ms windows security and the continuous pop ups look like ms windows security and are telling me that my computer is on its last leg and respond quickly. All I have to do is register my copy of their software for $49.99. only it is calling itself XP Home Security 2011. I have been trying everything with microsoft. trouble shooting, scanning for everything, malicious software removal tool with no results. It is still there and I cannot access anything firefox or anything else the normal way. I have to go to my downloads, click on one of my ms windows applications to run but instead of running it I click on the the info about the applications all that and firefox opens to display the microsoft info page then from there I can navigate the web, check my email etc. after two days of this I thought maybe I could find the solution from mozilla. So here I am. I really need help. Is there anyone out there that can help?
