Depending on what browser you are having these issues on, using the AdBlock Plus Add-on will let you manage pop-ups that are appearing in the browser.
I see that some of your issues are in the browser, but from the problem description unclear what (if anything) is happening when the browser is closed.
Searching for the exact message may indeed get you more specific information.
Don't panic and think you have to try more and different software, etc. It is very easy to get too many cleaners/anti-virus, etc running at once and they will give you more of a mess than you have.
I also vote for Avast Free & MalwareBytes - plus scrupulous checking of links before you open them.
