Remove ClearThink Ads (Permanent Removal)


Strange ClearThink ads start to appear and you cannot remove them.

In order to remove ClearThink scam, first you need to uninstall the adware program from your add/remove programs. Clearthink claims that it will enhance your browsing experience, by providing you with the best online deals and prices. On the contrary, it will overwhelm you with annoying pop-ups and advertisements. It may look like a legitimate service, however, the add-on creator decided to use deceptive promotion methods. This particular browser extension will screw your browser, by making it slow and often unresponsive. You probably infected with clearthink, when you have installed a freeware program that was bundled with it. Such programs can be downloaded from a variety of shady download websites. Almost, all the free programs in the internet are bundled with additional spyware programs. You are presented with a choice to accept or decline the installation, but at the end you will get infected. Clearthink  is categorized as an adware extension, because it can spread unregulated commercials that may lead to installation of additional adware or malware. Clearthink might not be malicious program by itself , but its sole purpose is to gain fake traffic. It may also disclose your personal information to third parties.
