Last Updated by Nick Steinberg on September 07, 2023

If you suspect Search Marquis has infected your Mac, you should immediately scan your Mac with a trusted antivirus program. This allows you to quickly find and remove the Search Marquis files from your Mac, as well as hard-to-detect threats like rootkits, worms, and spyware. You can then restore your browser settings to get rid of any trace of Search Marquis.

I tested over a dozen Mac antivirus programs, and Intego is the best macOS antivirus with a 100% detection rate for all types of malware (including Search Marquis). I strongly suggest you protect yourself from any further infections by keeping Intego’s real-time protection feature turned on at all times.

Intego is an antivirus specifically developed for macOS, so it’s no surprise that it’s adept at identifying and eliminating the Search Marquis virus. Intego enhances Apple’s already robust security features and even improved my Mac’s overall performance with its impressive suite of optimization tools.

You should start by performing a full scan to look for the Search Marquis file on your Mac (although there are also quick, custom, and scheduled scans available). Intego’s VirusBarrier malware scanner is fast and detected 100% of all malware samples in tests. Even more impressively, Intego accurately identified all infected files — there were no false positives.

A full scan takes around 30 minutes to complete, but it’s important that you run it to completion. When you stop a scan partway through, you may end up missing copies of Search Marquis or other viruses hiding on your Mac.

Once you’ve finished scanning your Mac with Intego, you’ll see a summary screen detailing any malware that was detected and quarantined. You can now permanently delete the Search Marquis file. I strongly recommend restarting your Mac and running another full system scan to ensure all malware is successfully removed, especially if you don’t regularly scan your Mac for infections.

This gives you a chance to see how well it performs against the Search Marquis virus before investing in your future protection. If you change your mind, you have up to 30 days to claim a refund.
