It might be a little late now to tell people this, but the government is shutting down a malware protection server at 12:01 am on Monday. What would happen is the malware would change how your computer looked up sites on the Internet. This would cause you to be redirected to the malware site. The government had a server in place that would correct this issue. This is being shut down on Monday.
You can check to see if you are in danger by visiting the following link- http://dns-ok.gov.au/ There was a US link, but it was not working at the time of this post. The link for more information and how to fix it if you are affected is located at http://www.dcwg.org/
This does not mean that you do not have any malware on your computer. It only check for DNS infections. Malwarebytes is a free anti-malware program. You can download it here.
