remove Search Marquis virus Mac

Are you a Mac user seeing Search Marquis instead of your usual search engine when using Firefox or Safari? If the answer is yes, your device may be infected with the Search Marquis virus.

Search Marquis is a browser hijacker that tweaks your browser settings and changes your default search engine to its own, forcing users onto a scam search engine.

Fortunately, we’ve got a tried and tested solution that explains how to remove the Search Marquis virus from your system in a few straightforward steps.

What is the Search Marquis malware?

Search Marquis, on its own, is a harmless search engine like Google. However, a Search Marquis malware infection is slightly different and is known as a browser hijacker – that is, it hijacks macOS browsers like Chrome, Safari, and Firefox and switches your default search engine to Search Marquis without your consent.

The search Marquis malware works by infecting your system and tampers with your browser settings, configuring a redirect that constantly sends you to searchmarquis.com. If you accidentally click any other banner ad, pop-up, or website where Search Marquis is disguised, it could lead to further infections.
