What can you expect fromGemius virus?

Gemius virus (or Win32/Trackware) is an adware[1] program which travels bundled with freeware. Therefore, people can accidentally install this potentially unwanted program (PUP) and cause themselves annoying problems. After infiltration adware starts delivering an excessive amount of online ads based on your interests. This PUP may predict what commercial content might be interesting to you by spying on you online activities. The main purpose of the Gemius adware is to place cookies[2] on your web browser, track non-personally identifiable[3] information about you and might send aggregated information to third-parties or affiliates. It claims to be collecting information related to the usage of online content only, for example, search terms, mostly visited websites, time spent and data entered in them, clicks, technical details about browser’s type, language, and settings, PC’s IP address, location, email address and so on. Nevertheless, it is stated that collected information is used for marketing purposes only; sharing this information with third-parties looks shady. You can never be sure to what third-parties such information may leak and for what purposes it may be used.That’s why we recommend Gemius removal as soon as this sneaky program appears on you PC. The easiest way to get rid of it is to run a full system scan with Reimage or another anti-malware program.

Genius virus may infiltrate random computers running any version of Windows OS and drop an extension on all most popular web browsers (Google Chrome, Mozilla Firefox, Internet Explorer). Then, adware starts delivering commercial third-party content to you. More precisely, it may generate pop-up, pop-under, banner, in-text, full-page and other forms of advertisements[4], which are typically marked as “Ads by Gemius.” Be aware that those ads[5] are closely related to third parties and may be linked to really suspicious websites. Therefore, in order to prevent exposing your computer to various cyber threats and avoid information leakage, we recommend you to remove Gemius from your computer without any delay.

How can this program get inside the system unnoticed?

Gemius is yet another dubious browser add-on, which is typically distributed using unfair distribution techniques the most common of which is known as “bundling.” This so-called marketing technique is used for spreading potentially unwanted programs, such as Zoom Zoom, MacSpend, Air Globe, PastaLeads and many others. This infiltration method allows attaching adware as an optional component to other freeware, such as download managers, PDF creators, media players and so on. Therefore, if you want to avoid Gemius hijack, you have to check every freeware before installing it. First of all, you should read EULA, Privacy Policy, and other accessible information that is related to your selected freeware. Besides, you should always select Advanced or Custom installation option and carefully monitor the entire installation process. Finally, you will have to uncheck all checkboxes, which claim that you agree to install “optional downloads,” such as Gemius redirect virus. If you will not do that, it’s very likely that you will install a whole bundle of programs instead of one.

How to get rid of Gemius ads?

Adware programs might be removed either manually or automatically. Manual Gemius removal is a little bit harder than automatic. It requires to investigate computer’s system, look for the adware, detect which program was responsible for bringing it inside, and find other suspicious applications that might have been installed on your PC and web browsers as well. Once you find, you have to delete them. However, if this task seems complicated and you wish someone would do it for you; we have a solution as well. You can remove Gemius with a help of anti-malware/anti-spyware programs. All you have to do is to install the necessary software, update it and run a full system scan.

You can remove Gemius automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.
