Remove ClearThink Ads (Uninstall Guide)

Tell your friends:
There are so many different types of malware it can be difficult to know what the things you should look out for are. With Trojan horses, adware, spyware, browser hijackers, ransomware and Potentially Unwanted Programs all posing constant threats to our online security there's certainly enough to be alarmed about. We're taking a closer look at adware called ClearThink. It belongs to the Yontoo adware family. Once installed, it will display pop-up ads and redirect you to misleading websites. Please use this guide to remove ClearThink ads and any associated malware from your computer.

Knowing how to protect your safety, your identity – and your sanity – when you're online is increasingly difficult but to stand a better chance it's important to understand more about what adware is and specifically what ClearThink is.

In short, it is software that is installed on your PC without your permission. It monitors your browsing habits by looking at the types of websites you are regularly visiting and then displays adverts that say "ClearThink Ads" that are tailored to those sites. In other scenarios, you might be shown pages or ads that you have no interest in whatsoever – these are usually of a slightly dubious nature. Take a look at these examples:

This one says that he media content is not shown properly. It says that you need to update you media player. The truth is you don't need to update anything, especially some kind of media player. What scammers mean by saying media player remains unclear, perhaps Windows Media Player? Who knows.

And this one is a pure classic. Important message. Slow computer? Yeah sure. Don't install such crappy software it won't improve your system's performance.

ClearThink manifests itself normally as a pop-up window, although it can also take the form of links (URLs) or pop-under pages – pages which hide beneath the page you are currently looking at. If you think that this sounds annoying – you'd be right! And although it can be tempting to dismiss adware as an irritating yet innocuous phenomena, there are many strains of ClearThink adware who are less about the advertising and more about using the information gathered on you for more sinister purposes; for example they might gather your data and then sell it on to a third party. Some particularly nasty adware can even monitor the keys you're typing and collect this information, may it be search queries, recently visited websites, etc. In addition to this, it slows down your computer's processor and your Internet connection, due to the tracking software it is running on your PC.

It's actually very easy to tell if you have this adware installed on your computer:
  • You are seeing a proliferation of pop-up adverts saying "ClearThink Ads" or "Ads by ClearThink"
  • You're seeing pop-under windows – often advertising gaming or adult websites
  • You notice a lot more advertising links to websites than previously
  • Your PC is running a lot more slowly all of a sudden
  • Your Internet connection seems a lot slower
The key thing to remember is to know what you are downloading. ClearThink most often comes bundled with other programs so make sure you recognize the developer or publisher's name and read the License Agreement carefully. Sadly, but I got this adware after downloading software from It's a very popular website and it's a bit shame that they are now participating in this pay per install networks and pushing adware.

How to protect yourself? You've heard it countless times, but don't open email attachments or links if you don't know the sender. You can also install pop-up blockers and a firewall on your PC and of course, download a good anti-malware program. And finally, don't download software from shady websites.

I've been infected – help! Run your anti-adware so it can find and remove infected programs. Then restart your computer and scan it again. Be careful because some adware is very difficult to remove so it might take a couple of tries. A good anti-virus should remove everything on your machine.
