Karate ads

[opr1945]

I got a new laptop Thursday. Now when I open a thread I find an ad between each and every post. Really annoying. This didn't happen on my previous laptop. Any suggestions for getting rid of the ads?

I use Chrome browser on each laptop. old one was Hewlett Packard. new one is chromebook by ASUS (I think it is best buy house brand). both entry level laptops.
