My mother in law was a victim of this. She called me saying her computer was infected and this malware program “Antivirus System PRO” had taken over her machine.

It did. Couldn't do anything without this “anti virus program” warning about other viruses. Luckily I had run into this before with my son's computer.

The solution is to download Malwarebytes’ Anti-Malware http://www.malwarebytes.org/mbam.php install it on all your computers and do the update. If “Antivirus System PRO” takes over your computer you won't be able to get on the Internet to download it then.

Good luck.

Malwarebytes = good recommendation. Worked for me as well.
