How to remove the Calendar New Tab browser hijacker

What kind of software is Calendar New Tab?

Calendar New Tab is a browser extension that we found while inspecting suspicious sites. It is endorsed as an extension that displays a calendar on the browser.

However, Calendar New Tab makes changes to browser settings in order to generate redirects to the calendarnewtab.com fake search engine. Due to this behavior, it is classified as a browser hijacker.

Calendar New Tab browser hijacker overview

Browser-hijacking software assigns promoted websites as browsers' homepages, default search engines, and new browser tab/window URLs. Hence, with Calendar New Tab installed: Web searches performed via the URL bar and new browser tabs/windows opened – result in redirects to the calendarnewtab.com site.

Illegitimate search engines are rarely capable of generating search results, so they redirect to genuine Internet search websites (e.g., Google, Bing, Yahoo, etc.). However, at the time of research, calendarnewtab.com landed on nearbyme.io – another fake search engine. Nearbyme.io can provide search results, although they are inaccurate and include sponsored, deceptive, and potentially malicious content.

It is pertinent to mention that browser-hijacking software can use persistence-ensuring techniques to prevent users from recovering their browsers.

Calendar New Tab likely spies on users' browsing activity. Browser hijackers usually target the following information: visited URLs, viewed webpages, searched queries, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, etc. The gathered information can be sold to third-parties or otherwise abused for profit.

In summary, the presence of software like Calendar New Tab on devices may result in system infections, severe privacy issues, financial losses, and even identity theft.

Browser hijacker examples

We have examined thousands of browser hijackers; Bigoloo, Quotes Srch Tab, Volume Extra – are merely a few of our latest finds.

Browser-hijacking software typically appears legitimate. It tends to offer a broad range of handy functionalities, which are rarely operational. It must be stressed that even if an application or a browser extension works as advertised – that is not definitive proof of either legitimacy or safety.

How did Calendar New Tab install on my computer?

We obtained Calendar New Tab from its "official" download webpage. In addition to misleading promotional pages, browser hijackers are commonly pushed through scam websites. Most users enter these webpages through redirects generated by sites using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive adverts, or installed adware.

Browser-hijacking software can also be bundled with ordinary programs. The risk of allowing bundled content into the system is increased by downloading from untrustworthy sources (e.g., freeware and free file-hosting websites, P2P sharing networks, etc.) and by rushing through installation processes (e.g., skipping sections, using "Easy/Quick" settings, etc.).

Intrusive advertisements proliferate browser-hijacking software as well. Some of these adverts can be triggered (by being clicked) to perform stealthy downloads/installations.

How to avoid installation of browser hijackers?

We recommend researching software and downloading only from official/verified channels. Furthermore, installation processes must be approached with care, e.g., by reading terms, exploring possible options, using the "Custom/Advance" settings, and opting out of all additional apps, extensions, features, etc.

We advise caution while browsing since fraudulent and dangerous online content usually appears legitimate and harmless. For example, despite their potentially innocuous appearance – intrusive advertisements redirect to highly questionable websites (e.g., gambling, pornography, adult dating, scam-promoting, etc.).

If you keep experiencing ads/redirects of this kind, check the device and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Calendar New Tab, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
