Russ, some of these Ads are pure spam, that take you to web sites you cant escape from unless you reset your machine. Are you able you to check if they legitimate?

Anyone else experienced this?

Do run a malware check. Try Malwarebytes - it is free.

You may find that RHP ads have been replaced by malware served ads.

Thanks Russ I'll try it - a sage, as usual..
