Gamesquest.co site offers to download questionable game-themed extension for Chrome

Download sources of Gamesquest.co

Gamesquest.co is a website that promotes Games Quest Chrome extension that allows accessing various online games from the browser. However, this extension is also known as a potentially unwanted program (PUP) and a browser hijacker that might be installed on Chrome without your knowledge.

Due to the stealthy infiltration strategy, users often refer to it as Gamesquest.co virus. However, it’s not a correct term to describe this cyber threat. It’s not malicious and cannot cause direct harm to the system. However, the hijacker might be the first step of serious malware attack.

After the Gamesquest.co hijack,[1] you might find changes to these changes to the browser or deal with annoying activities:

  • hijacker might install not only Gamesquest.co Google Chrome extension, but other suspicious add-ons as well;
  • it might replace default homepage or/and search engine. It is reported of rerouting search queries via http://www.gamesquest.co/yhs/search?q=;
  • the PUP might display ads, pop-up, and banners promoting various games, programs or similar content;
  • it might trigger sudden redirects to affiliate websites,
  • a collection of non-personal and technical information which is used for advertising purposes.

Therefore, this gaming-related extension might cause lots of negative features and might diminish browsing experience significantly. Additionally, it might put user’s privacy at risk and increase chances to encounter various cyber threats.

The hijacker might alter search settings to redirect user’s search queries to Yahoo results page. Indeed, it’s a legitimate service, and it seems that developers generate revenue from Yahoo affiliate program. However, it might also trigger redirects to other promotional sites once you click on a results link.

Such Gamesquest.co redirect tendencies are concerning because you might be forced to visit scam, phishing or malicious website. PUPs are often exploited by cyber criminals. Thus, to avoid becoming a victim of another cybercrime, you should take care of your computer’s security.

You should remove Gamesquest.co as soon as it is installed on your browser. If you have installed it yourself, you should not encounter any difficulties with its elimination. However, if it arrived in a software bundle, you may need to work harder on the removal procedure.

We suggest automatic Gamesquest.co removal option with Reimage which allows terminating the hijacker within a couple of minutes. However, if you want to get rid of it manually, follow the guide at the end of the article.

The shady distribution strategy

As we have mentioned at the beginning, GamesQuest extension, created by Chinese[2] company FirstGate Mobile Limited, has an official website from which users can download it. Additionally, it is available on Chrome web store.[3] However, direct downloads are no the only distribution methods used by developers.

The add-in has been noticed spreading in freeware packages as an optional component. It might be offered to download with media players, PDF converters, and many other free applications. However, if you use Advanced/Custom installation, you might overlook this offer and let all undesired apps to infiltrate the system without your knowledge.

Recommended/Standard installation settings do not inform about additional third-party apps that want to be installed together with a primary program. Thus, instead of this setup, you should use Advanced settings and opt out all of these “optional downloads.”

Uninstall Gamesquest.co from Google Chrome

If you tried to remove Gamesquest.co as an ordinary Chrome extension, you might have noticed that it came back again. Indeed, it might happen due to the specific hijacker’s functionality. Once it arrived on the system in the software bundle, it might alter browser’s settings to stay as long as possible.

To get rid of it entirely, you have to find and delete all hijacker-related entries that may have been installed on your PC and reset the browser to the default to revert modifications.
