What is search.hthecalendar.co?

search.hthecalendar.co is one of many browser hijackers and fake search engines also known as The Calendar. The software is distributed by a Cyprus-based company called Polarity Technologies Ltd., and is installed on the browser as an extension, add-on, or program on the Windows Operating System.

search.hthecalendar.co browser hijacker

You can ascertain if it is installed on your browser by studying its design: this fake browser engine contains two search boxes (the main one in the middle of the search engine and a smaller one in the top-left corner) and various graphic icons with links to websites such as amazon.com, gmail.com, yahoo.com, almanac.com, and timeanddate.com You can also see that it has an integrated clock showing the local time and a tab with the current local weather, which encourages you to visit a website called National Weather Agency. This browser hijacker seems very similar to others such as search.bittsearch.com and feed.amazingtab.com The only difference is that not all have the integrated clock and these search engines usually promote different websites/have different graphic icons with links. When an enquiry is made, this particular fake search engine redirects you to search.yahoo.com, which is a search engine owned by Yahoo. The Calendar browser hijacker targets the most popular browsers such as Safari, Google Chrome, Mozilla Firefox, Microsoft Edge, and Internet Explorer. Depending on the web browser, it can be installed as an extension, a program on the operating system, or an add-on. For example, if you are using Mozilla Firefox, you will find The Calendar installed as an extension. If Google Chrome is your default web browser, it is installed as an extension. The same applies to Safari. If you are using Microsoft Edge or Internet Explorer, it is installed on Windows as a separate program. Once installed, it changes the homepage and search engine to search.hthecalendar.co When you open a new tab, your hijacked web browser also opens the search.hthecalendar.co website. This situation allows first-party publisher or Partner Cookies to be installed on your browser, adds additional search-related services, and changes the error page functionality.

There are many browser hijackers such as The Calendar, and the number is growing daily. Even if they appear different and have various 'useful' features to offer, most affect your hijacked browser in similar ways. These fake search engines often have integrated shortcuts to popular websites such as gmail.com or yahoo, and extra shortcuts to various unknown websites. These dubious sites claim to be legitimate search engines, but collect information about your online behaviour or generate revenue by redirecting to various other (mostly unknown) websites. You might also experience misleading redirects, unwanted ads, etc. Clicking on these links could result in serious problems. Your computer might be infected by malware and viruses, could become more vulnerable to hacker attacks, and so on.

How did search.hthecalendar.co install on my computer?

Browser hijackers such as The Calendar are installed by dangerous, free software, shareware or ad-supporting programs, which include various toolbars, browser plug-ins, and so on. Browser hijackers are often bundled with free programs that you download from the Internet. In most cases, these programs are free since they include browser hijackers or adware programs. Free software is not actually 'free'. In some cases, you do not even need to install anything to have your browser hijacked. It is sometimes enough to click a pop-up button, which does not necessarily do what it states, and then installs an app onto your browser or operating system. There are also cases whereby the browser could be hijacked through emails, torrents, or software download managers.

How to avoid installation of potentially unwanted applications?

Remember that software is rarely 'free', even if you do not have to pay for it (usually, there is a 'catch' or related scam). Check if the program you want to download and install is secure and legitimate. Google it to see what information you can find. When installing a particular program, check "Advanced" or "Custom" installation options, and do not jump through the installation steps without checking the content of each. Look for ticked checkboxes where it states that you 'agree' to download various extra features or software (which could be browser hijackers). These checkboxes are usually ticked by default. Do not click suspicious pop-up ads and avoid visiting untrustworthy websites. Keep your real-time antivirus software enabled and ensure that you have the latest operating system and browser version. Do not click links within emails from unknown senders. The Internet is full of unwanted software and the easiest way to avoid it is to carefully choose what to click, download, and install. If your computer is already infected with The Calendar, we recommend running a scan with Spyhunter for Windows to automatically eliminate this browser hijacker.
