Forgot I have malwarebytes on this laptop. Ran that and it detected adware.gameplayads. Described as a, get this...dropdown coupon advertiser! So I removed it.

But I still see signs of it. For example, in my signature, the word Multiple Sclerosis is hyperlinked, but not in every post. Weird. I will run malwarebytes again.

Razzle51, hope you can remove your problem also! I see you are also in Iowa; I'm near Cedar Rapids. Are we neighbors?
