Inomist.com pop up

[Guest El Satanico]

It's a pop up and if you don't close it within a few seconds it opens up a bunch of porn pop ups.

 

To be honest, I only have problems with it while looking at porn sites. However, it's the same free sites I've been going to for awhile and it's just started two months ago.

 

Has anyone else experienced this and if so how do you stop it?
