Yesterday I tried to install Bluestack App and it asked to install another program to meet the system requirements. After the installation Firefox got affected with this Trovi Hijacker. I still remembered previous hijacker of Nav Links.
I described about it how to remove it from PC, but now this Trovi is similar problem for browsers only.
Just remove any programs that are installed when the browser got infected. If this wasn’t solved your problem then go for the second step.
For my problem there was Search protect program that was removed from Add or Remove programs.
Download ADWcleaner, run it, your PC would get cleaned automatically from this program.
