This is like a little bug you can't swat. It installs like a search engine right where your tabs normally are. I first found this in google chrome, but it quickly spread to all my browsers. IE and Mozzilla Firefox.

This application force-installs itself on your computer and hacks your browser, forcing it to run a stupid search engine. It is not malicious malware, but it is a very annoying adware!

I downloaded a program from the web and this was loaded along with program I wanted. Been trying to get rid it ever since. They need another security rating, annoying.
