Sounds like a case of adware/malware on your computer Bob.
Personally, I run Malwarebytes Anti Malware along with Ad Block Plus on my computer and since ive done that ive never had a problem. Been almost three years now. For the first time in my life, im actually going to have to buy a new computer because this one is worn out physically instead of crashing or internal problems.

I actually spend the 30 bucks a year for Malwarebytes Premium version, but to be honest, the free version probably works just the same. I obviously also keep my pop up blocker on 24/7. Ive never turned it off. The only time that gets annoying is when you click on a link and it wont open but ive found right clicking and opening in a new tab is easy enough for me.
I honestly cannot believe how well it has worked for me.
