Well, to be fair, that isn’t all that Clear Think is capable of – it also attracts malware, modifies some of your browser settings without bothering to ask for permission, overwhelms the entire PC system and slows it down to a crawl.

It is classified as a potentially unwanted adware program for a reason and the sooner you remove it, the better.

How did I get infected with?

The most unoriginal infiltration technique (as well the most effective one) is bundled freeware. That only comes to show once again how important it is to be cautious every time you decide to download programs off of the Internet. So if you’re left there baffled as to how Clear Think penetrated into your machine without being noticed by the antivirus system, here’s the answer. You probably installed some questionable software from a questionable website and you didn’t pay much attention to the installation process. The virus was attached to the programs in the bundle like some kind of a bonus. However, as you are quickly to be convinced, this is an incredibly unwanted bonus that has all the potential needed to wreak havoc all over the computer. Unfortunately, adware infections aren’t the only possible “bonuses” – Trojans, for example, follow the same path. It’s highly recommended that you opt for the Advanced option instead of rushing towards the “next” button. Also, checking the Terms and Conditions is quite a good idea because you certainly want to be aware of everything you accept and everything you agree to install. Of course, all traditional methods for malware distribution such as spam email-attachments, fake messages, bogus program updates, etc. are still painfully efficient too. You have to be extremely watchful when browsing the Web unless you’re willing to infect your own device with parasites.

Why are these ads dangerous?

First and foremost, the Clear Think virus is very annoying. If the endless pile of coupons, discounts, deals and offers, in-texts, banners, video ads, pop-ups and pop-unders doesn’t affect your ability to think clearly, it will definitely affect your computer’s ability to work normally. This malicious program is compatible with the most commonly used browsers out there so once it gets installed, it immediately injects Mozilla Firefox, Google Chrome and Internet Explorer with commercials. Once very important piece of information, however, is that the ads are possibly corrupted as the only web links Clear Think displays you are sponsored. That doesn’t correspond well with your cyber safety, does it? The program comes for free and its developers generate profit by some dubious monetizing methods that could lead you to malicious websites filled with malware. Long story short, you should avoid the ads brought by Clear Think because they are simply too unreliable to trust. Same thing goes to all supposed software updates or additional toolbars that the parasite might try to force on you. In reality the PC probably doesn’t need any of them; that’s just a clever and unfair way to make you install malware and compromise your own device even further. Clear Think’s manipulations don’t end here, though, as the parasite has access to your browsing-related data (including search queries, pages visited, passwords) and sends it straight to hackers. As you can clearly see, Clear Think has to be quickly uninstalled. To do so manually, you can follow the removal steps we’ve provided down below.
