How can I keep these websites from popping up on my computer?

Why my computer has window that keep popping up and scanning my computer for error?

• I clicked on the icon that unfamiliar on my folder, after that, it just keep installing something. I tried to stopped it but it just keep going and going until the program installed. Then this program keep popping and scanning my computer for error. I tried to re- start my computer wish that this will go away but still popping and popping. I tried to co-operate with what that program, followed what it asking but I am afraid that they might get my personal information, because it asked me to input credit card numbers, my name, and address. The program asking me to buy computer's protection, I don't really want any. How can I get rid off this program? Can someone show me how? I even unplug all internet connection for that computer because I am afraid that they can access personal information.

• Answer:

  You have a virus my friend or at the very least malware. You are right to fear access to your personal info. Do a FULL scan with your antivirus software, If you don't have any Windows now has one for free called Microsoft Security Essentials available from the microsoft web site. You should then ALSO scan with a quality malware product like Malwarebytes. If this program is preventing you from using your pc to achieve this try ctrl+ alt +del to see if you can temporaraly disable it, you may have to try and find it under the process tab as they usually don't show up under the application tab. Try typing the name of the program into google and you should be able to find out exactly what it is and if there are any further steps needed to fully remove it. Don't download any program that asks for money or credit details.
