Does this sound like your story? You see pop-up advertisements from view.contextualyield.com while browsing sites that typically don’t advertise in pop-up windows. The pop-ups manage to bypass the built-in pop-up blockers in Mozilla Firefox, Google Chrome, Internet Explorer or Safari. Perhaps the view.contextualyield.com pop ups appear when clicking search results from Google? Or does the pop-ups show up even when you’re not browsing?

Here’s a screenshot of the view.contextualyield.com pop-up ad when it showed up on my machine:

(Sorry for the ridiculous use of watermarks. I have to do it to stop the copy-cats.)

If this description sounds like your computer, you probably have some adware installed on your machine that pops up the view.contextualyield.com ads. Contacting the owner of the website would be a waste of time. They are not responsible for the ads. I’ll try help you with the view.contextualyield.com removal in this blog post.

Those that have been spending some time on this blog already know this, but here we go: A little while back I dedicated some of my lab computers and intentionally installed some adware programs on them. I have been tracking the behaviour on these computers to see what kinds of advertisements that are displayed. I’m also looking on other interesting things such as if the adware updates itself automatically, or if it downloads additional unwanted software on the computers. I first found the view.contextualyield.com pop-up on one of these lab computers.

view.contextualyield.com resolves to 46.105.156.73. view.contextualyield.com was registered on 2015-06-25. bycontext.com is also located at the same IP according to YouGetSignal’s reverse lookup service.

So, how do you remove the view.contextualyield.com pop-up ads? On the machine where I got the view.contextualyield.com ads I had istartsurf, MedPlayerNewVersion and Movie Wizard installed. I removed them with FreeFixer and that stopped the view.contextualyield.com pop-ups and all the other ads I was getting in Mozilla Firefox.

It seems as view.contextualyield.com is getting quite a lot of traffic, based on Alexa’s traffic rank:

The issue with this type of pop-up is that it can be initiated by many variants of adware. This makes it impossible to say exactly what you need to remove to stop the pop-ups.

So, what can be done to solve the problem? To remove the view.contextualyield.com pop-up ads you need to review your computer for adware or other types of unwanted software and uninstall it. Here’s my suggested removal procedure:

1. What software do you have installed if you look in the Add/Remove programs dialog in the Windows Control Panel? Something that you don’t remember installing yourself or that was recently installed?
2. You can also check the add-ons you have in your browsers. Same thing here, do you see anything that you don’t remember installing?
3. If that didn’t solve the problem, you can give FreeFixer a try. FreeFixer is built to assist users when manually tracking down adware and other types of unwanted software. It is a freeware utility that I’ve been working since 2006 and it scans your computer at lots of locations where unwanted software is known to hook into your system. If you would like to get additional details about a file in FreeFixer’s scan result, you can just click the More Info link for that file and a web page with a VirusTotal report will open up, which can be very useful to determine if the file is safe or malware:
