Seems a common problem. How to fix?
Pop-ups are usually advertisements put in place to load with the site you are visiting.
Try this: http://adblockplus.org/en/ and this: http://www.mywot.com/ Former blocks the ads from ever appearing; the latter rates safety of the ads that do show.
Clarification request here: Ads displaying are a part of the website, and not a true pop-up in the sense that you have a separate window for that ad? Example: Ad on top of the site that pops up in the center of window you are visiting; it follows the scrolled window only to remain centered in the display at all times? AdBlock Plus will take care of that. A good example of a really obnoxious advert that will not be ignored. Gone with AdBlock.
Be sure to donate to them; add-on is free to use otherwise and is customizable.
Vendor will work with users to continually update against unwanted and malicious and aggressive advertisements; users send in info for them to update.
I expect this has already been covered but I have searched and followed other peoples ideas but I am still stuck. Also I have seen the word pop-unders... i'm not sure what these are as not seen them like this before. It's usually rude or gambling pop-ups that seem to be placed on top of a website but not in its own window. It comes with a little cross to click to get rid of but I can't help but think that if I don't deal with it, it will get worse.
It seems to happen on the majority of websites (even google). I have tried CCleaner twice which completely cleared everything it found and virus checker. What can I do next? I have even tried switching from IE to Firefox but no luck.
Any help would be brilliant,
