Ads pop up on webpages and I cannot even close out of them

[Jszostak]

A couple weeks ago I started getting these ads that appear whenever I open Internet explorer or Firefox. It is always in the bottom left of the screen and they cannot be closed out of. The most I can do is click "hide ad" and then you can only see a small amount of it, after a few mins though it will becomes full size again. I have tried malwarebytes to try and get rid of it but that did not work. It doesn't matter what webpages I'm on, the ad is always there and it is significantly slowing down my computer. How do I get rid of this?

Please help!

No, please do not click to update.  This is a SCAM

 

Just to make sure all is okay I would suggest following the advice from the topic here Available Assistance for Possibly Infected Computers and having one of the Experts assist you with looking into your issue.
