Search.microcosmtab.com redirect removal instructions

What is search.microcosmtab.com?

search.microcosmtab.com is a fake Internet search engine that supposedly enhances the web browsing experience by generating improved results and providing quick access to popular websites. Initially, this site may appear legitimate and useful, however, search.microcosmtab.com is promoted via a deceptive application called Microcosm. This app claims to allow users to change new tab backgrounds and display local weather forecasts. It may seem legitimate, however, Microcosm usually infiltrates systems without permission. Furthermore, it is designed modify web browser options without permission and record various user-system information. For these reasons, Microcosm is categorized as a potentially unwanted program (PUP) and a browser hijacker.

search.microcosmtab.com browser hijacker

Immediately after infiltration, search.microcosmtab.com hijacks Internet Explorer, Google Chrome, and Mozilla Firefox, stealthily assigning the homepage, new tab URL, and default search engine settings to search.microcosmtab.com. Although these changes may seem insignificant, users are unable to revert them - search.microcosmtab.com continues to reassign browser options when attempts are made to change them. Therefore, returning browsers to their previous states becomes impossible and users are encouraged to visit search.microcosmtab.com when they open a new browser tab or search via the URL bar. Microcosm app is essentially used to deceptively build traffic for search.microcosmtab.com (at the cost of users' web browsing experience). As mentioned above, Microcosm (and search.microcosmtab.com) continually gather sensitive data (mostly relating to Internet browsing habits). Developers sell this data to third parties (potentially, cyber criminals). Since the collected data might contain personal details, the presence of apps such as search.microcosmtab.com might lead to serious privacy issues or even identity theft. Modification of browser options and information tracking is very common to potentially unwanted programs, however, in some cases, these programs mine cryptocurrency or run other unwanted processes in the background. By misusing resources, PUPs significantly diminish performance. For these reasons, we recommend that you uninstall apps such as Microcosm without delay.

The Internet is full of browser-hijacking applications virtually identical to Microcosm. The list of examples includes (but is not limited to) Movies Tab, Incognito Searches, Polimva, and Sports Score. Note that these apps offer different useful features, however, the claims are merely attempts to give the impression of legitimacy. Applications such as Microcosm are designed only to generate revenue for the developers. Only a small percentage of these PUPs provide the functionality promised - most deliver no real value for regular users and pose a direct threat to your privacy and Internet browsing safety. Fake search engines feed users with false results and 'malvertising' ads. The generated ads/results typically lead to malicious websites. Furthermore, some of these ads run scripts that download and install malware/PUPs. Therefore, using a fake Internet search engine is very risky.

How did search.microcosmtab.com install on my computer?

search.microcosmtab.com has an official download website, however, these programs are also proliferated using a deceptive marketing method called "bundling" and 'malvertising' ads. Therefore, browser hijackers often infiltrate systems due to users' lack of knowledge and careless behavior. "Bundling" is stealth installation of potentially unwanted programs together with regular (usually free) software. Developers hide "bundled" apps within various sections (e.g., "Custom/Advanced" settings) of the download/installation processes - they do not properly disclose this information. Therefore, rushing these processes, skipping steps, and clicking ads, exposes systems to risk of various infections.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution and, thus, it is very important to pay close attention when browsing the Internet and especially when downloading/installing software. Cyber criminals invest a great deal of time and effort into designing malicious ads. Therefore, these ads often appear legitimate, however, they are distinguishable for their redirects - most lead to survey, gambling, adult dating, pornography, and other dubious websites. They are displayed by fake search engines, and various adware-type applications. If you encounter 'malvertising' ads, uninstall all suspicious applications/browser plug-ins. In addition, analyze each step of the download/installation process and opt-out of all third party applications. Note that third party downloaders/installers often promote malicious apps - criminals monetize these tools using the "bundling" method. Therefore, we strongly advise you to avoid using these tools.
