Search.hthecalendar.co Removal Guide

Search.hthecalendar.co appears to be a browser hijacker that could enter the system after installing a suspicious browser plugin available on thecalendar.co. Apparently, once the extension settles in the affected browser might start loading the search engine in question instead of user’s usual homepage or default search engine. It is essential to explain, this tool could introduce you to potentially malicious advertising content as our specialists noticed the application might display results through a modified search.yahoo.com version. Therefore, we do not advise using it if you do not want to risk seeing possibly malicious advertising content. Users who choose to eliminate Search.hthecalendar.co should remove the extension it came with the way it is shown in the instructions located below this report. Of course, if you would like to learn more about this browser hijacker before deciding whether it is wise to use it, you should read the article first.

The software’s Privacy Policy and End User License Agreement statements reveal Search.hthecalendar.co was created by a company named Polarity Technologies Ltd. Our specialists have already seen this name many times before as this is not the first browser hijacker created by these developers (e.g., Search.hmyutilitybox.co, Search.searchtmpn.com, Search.hmylocaltransit.co, Search.searchlivesportson.com, and so on). Thus, we doubt the mentioned company could be considered reliable. On the contrary, it raises even more suspicions on the discussed application.

Furthermore, users should know Search.hthecalendar.co works only on Internet Explorer and Mozilla Firefox so far. The browsers could be affected differently as the plugin may alter different browser preferences, although our specialists confirm it is supposed to be either the browser’s start page or its default search engine. Being redirect to it whenever opening the browser or starting a new search might seem annoying, but unfortunately, it could be potentially dangerous too if you decide to use the application to surf the Internet. According to it End User License Agreement paper, the software way collect search keywords and such information could be used “to serve relevant ads to you and/or to monitor the performance of the search services.”

In other words, the browser hijacker could display targeted advertising content and since there is not knowing where it may come from, there is a chance some of it might be potentially malicious, e.g., ads offering to participate in fake surveys or lotteries, pop-ups redirecting to sites containing malware or threats similar to Search.hthecalendar.co, etc. We believe such content could be added to the gathered results at the time the user gets redirected to a modified search.yahoo.com version. Users may not necessarily encounter potentially dangerous ads as we cannot be entirely sure, but knowing there is such a chance we do not think it would be wise to keep using the unreliable search engine.

For those who would like to erase Search.hthecalendar.co manually we would recommend completing the steps shown in the instructions available below.
