Replying to Hate to make another virus thread but...

A really weird warning just popped up on my computer. NS got completely blocked and then this was shown:

"Reported Attack Site!

This web site at greatprotectplus.com has been reported as an attack site and has been blocked based on your security preferences.

Attack sites try to install programs that steal private information, use your computer to attack others, or damage your system.

Some attack sites intentionally distribute harmful software, but many are compromised without the knowledge or permission of their owners."

What is going on?
