Our library patron had a computer problem. He had neglected to download any anti-virus protection for his personal Windows 7 notebook computer. Also, when a rogue “anti-spyware” program asked to be installed, he had clicked “ok.”
Now, pop-ups from this fake helper application were keeping him from surfing the web or running any programs.
With the help of the free downloads listed in this article, particularly Malwarebytes (http://www.malwarebytes.org), I was able to free his computer from its scourge and get him free continuing anti-virus protection to boot (Microsoft Security Essentials, http://www.microsoft.com/security_essentials).
