Search.myonlinecalendar hijacker pushes sponsored content instead of relevant search results

Search.myonlinecalendar.co is a fake search engine that takes advantage of unsuspecting computer users and generates revenue for the developers. This virus may delude computer users by its well-considered appearance since it looks just like Google, Bing, Yahoo and offers “handy” tools. However, we encourage the users to reconsider, whether they benefit from this fake search engine and be aware of the complicated My Online Calendar removal process.
Once the spyware is installed, it alters the new tab URL, homepage, and default search engine by assigning to search.myonlinecalendar.co without user’s permission. The changes may not seem significant because the virus redirects you to search.yahoo.com and displays your search results.
However, we can assure you that this is not the official Yahoo website. You can make sure by checking the link in your the address bar – it differs from the original Yahoo link. Besides, users may not be aware that this browser hijacker[1] generates a vast of malicious ads in the search results and increases the risks of getting infected.
Also, some people underestimate the malware and think that they will be able to remove it as soon as they want. The problem with search.myonlinecalendar removal is that it stealthily downloads other potentially unwanted programs (PUPs) and plug-ins. They are designed to reassign the above-mentioned browser settings, once the user tries to change them to the previous state.
If that is not enough, these PUPs and plug-ins collect browsing-related data (IP address[2], geolocation, etc.), which might be personally identifiable and lead to severe privacy issues. The developer, Polarity Technologies Ltd, clearly states that “by using the services, you are consenting to grant Polarity permission to collect your URLs and search data, including search queries that may contain personally identifiable information, share them with third parties, and use search-related cookies.”
Another downside of search.myonlinecalendar virus is that it continuously cause redirects to suspicious third-party websites such as online adult dating, gambling or e-shops. Even an inadvertent click on the ad can trigger an automatic installation of other types of malware into your system.
Thus, even if it may seem that this browser hijacker aims to improve your search experience, in reality, the primary goal is to generate malicious advertising and obtain revenue for its developers.
If you encounter redirects to search.myonlinecalendar.co or annoying pop-ups, we recommend you to scan your computer using FortectIntego security software to remove the infected files easily.

Suspicious software can be downloaded together with other free apps
Developers not only invested in the appealing appearance of the fake search engine but also considered the deceptive tricks on how to swindle users into downloading it. Please pay attention to these insights from Dieviren.de team[3] on how to prevent browser hijacking.
Most computer users rush to skip all the steps while installing new applications; thus, they choose the Quick/Recommended option, which hides the information about the possible potentially unwanted programs. This way users are not able to detect the virus and unconsciously installs it.
Therefore, you should always opt for Custom/Advanced settings and never agree to download any types of unrecognized applications while downloading other regular programs. If you already got tricked, uninstall all suspicious PUPs and plug-ins.
