If your web browser is randomly being redirected to the “Ads not by this site” advertisements then your computer is infected with an adware program.

The “Ads not by this site” adware program is bundled with other free software that you download off of the Internet. Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed adware without your knowledge.
Once this malicious program is installed, whenever you will browse the Internet, an ad from Ads not by this site will randomly pop-up.
These ads are aimed to promote the installation of additional questionable content including web browser toolbars, optimization utilities and other products, all so the adware publisher can generate pay-per-click revenue.
When infected with the “Ads not by this site” adware, other common symptoms include:
- Advertising banners are injected with the web pages that you are visiting.
- Random web page text is turned into hyperlinks.
- Browser popups appear which recommend fake updates or other software.
- Other unwanted adware programs might get installed without the user’s knowledge.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

THANK YOU SO MUCH! This not only got rid of the ads but it also fixed another issue I was having where I couldn’t watch videos on certain sites. (Netflix, IMDB, etc.) You my friend are amazing.
One thing I think I had to remove from my addoes actually called itself “Youtube AdBlocker,” but was not at all associated with the actual Adblock Firefox addon. Keep your eyes peeled for this. And, thank you Stelian, this thing has been bugging me for a while now.
I just removed the “Youtube Adblocker” as well. It fixed it immediately.
Thanks Stelian,
I ended up in your site looking to get rid of the “Ads not by this page”. I had to get rid of SK-enhancer and surf-and-keep.
