What is MegaSearch?

MegaSearch (also known as MegaSearch Toolbar) is another program, which belongs to potentially unwanted program or browser hijacker category. We say so because this toolbar can easily enter computers unnoticed in a bundle with other applications. In most of the cases, its distribution is closely related to freeware and shareware, so you have to be very careful when downloading such software to your computer. For more information about that, you should check the next paragraph. In addition, once MegaSearch gets ability to infiltrate its target PC system, it may hijack all web browsers, that are installed on it, including Internet Explorer, Google Chrome, Mozilla Firefox and other ones. Typically, it alters the default search engine or the homepage and gets ability to interrupt into each of victim’s search sessions. What is initiated by this hijacker? Beware that in most of the cases MegaSearch displays commercial pop-up notifications and may even start tracking people’s activity on the Internet. Once it collects required information, this program sends gathered data to unknown third parties. Besides, you must keep in mind that this program may show you altered search results, so you shouldn’t use it for your searches. Otherwise, you may be tricked into visiting unknown and very questionable sites. To sum up, technically MegaSearch is not considered to be a virus, so it may not be detected by some of anti-spywares. However, it’s clear that it may cause lots of issues for its users. That’s why we highly recommend scanning computer with Reimage or similar anti-spyware after detecting this hijacker on your computer. If you have just noticed this toolbar on your PC, you should waste no time and remove it from there because otherwise you may tricked into visiting insecure websites or installing other adware/browser hijacker on the system.

How can MegaSearch hijack my computer?

MegaSearch and similar potentially unwanted programs are mostly distributed in a bundle with other programs. These programs are actively spread on the Internet for free, so there is no surprise why their developers have decided to start using bundling for spreading them. Beware that you may download this application in a bundle with PDF creators, download managers, video recording software and similar applications. In order to avoid such unexpected downloads, you should pay more attention to freeware’s installation and uncheck all check boxes that agree with the installation of various toolbars, browser plugins, extensions and add-ons. For getting such ability, you should select Custom or Advanced installation option of the freeware. Once executed, MegaSearch creates a directory, drops some files in it and modifies the registry in order to register itself as a browser add-on. As a result, it starts showing up within Internet Explorer, Google Chrome and Mozilla Firefox browsers every time people start their browsing.

How to remove MegaSearch virus?

If you noticed MegaSearch redirects to unknown websites, continuous pop-up ads and similar activity, your PC was affected by MegaSearch virus.
