What is LookThisUp?

LookThisUp is another untrustworthy application that may initiate undesirable operations on your computer. Security experts name this application as an adware or potentially unwanted program because it has ability to get inside PC without any permission asked and then perform questionable operations. You may easily get tricked and believe that this browser add-on is beneficial as it is promoted as an advanced search tool. However, the most of PC users start looking for its uninstall wizard just a few days after its installation. That's because LookThisUp is a questionble browser plug-in, which may start generating various commercial offers and redirecting users to predetermined websites. Although it might seem harmless, we cannot say so. LookThisUp redirects may expose you to unfamiliar websites, which may contain infected files and suspicious links. In addition, you may be rerouted to websites that are sponsored by cyber criminals and used for really dangerous activities. If you are experiencing 'Ads by LookThisUp', please ignore them and remove this program as soon as possible. Moreover, this untrustworthy program is also capable of tracking people's browsing activities and accumulating such information as IP addresses, search queries, visited websites, browsing history, and other data. Privacy policy of this program notifies that it will gather your browsing habits. However, you can never know what hand it may be sent to. Thus, we strongly recommend reconsidering reliability of this program and, if it has started initiating problems on each of your web browsers, removing this program from the system.

How can LookThisUp hijack my computer?

LookThisUp is distributed via two ways – official site and free software. Typically, this questionable application gets installed silently and without users' consent. It may happen if you download free programs and do this not attentively enough. Free software is usually supported by third parties, therefore it is bundled with browser extensions, add-ons, plug-ins, toolbars and other additional applications. 'Advanced' and 'Custom' installation options disclose such additional offers and allow people to opt out of them. In contrast, 'Quick' or 'Recommended' installation doesn't reveal if the program is bundled or not. There are several tips that can help you prevent the access of LookThisUp virus and other potentially unwanted programs. First of all, you should avoid quick installation of the free software. It is always advisable to visit official site of the program you need and download it only after reading End-user license agreement (EULA). In addition, a reputable anti-spyware would also help you while dealing with various unwanted intruders. If Lookthisup or other useless browser add-on has already started initiating pop-ups and redirects on your computer, remove it from your PC system right away!
