If you think your Mac has a virus this is how to remove it for free

This guide helps you identify and remove malware from your Mac, offering free solutions. Many websites promoting Mac malware removal are actually selling antivirus software, but this guide provides unbiased advice. We'll use "malware" and "virus" interchangeably, though they are distinct. Malware often disguises itself as legitimate software, while viruses are small, hidden code fragments. Ransomware, adware, and phishing attempts are also threats.

We recommend reading our articles on Mac security tips and the best Mac antivirus apps (Intego is our top pick).

Identifying a Mac Virus:

Sudden slowdowns, crashes, error messages, loud fan noise, unexpected pop-up windows, or unknown toolbars/applications are potential signs of malware. However, these symptoms don't automatically indicate a virus. Mac malware is rare due to Apple's macOS security and the difficulty of virus propagation.

Symptoms of Mac Malware:

• Significant performance slowdown.
• New, unwanted browser toolbars.
• Unexpected search engine redirects.
• Excessive website ads.
• Random redirects to spam/advertising pages.
• Unexpected pop-up ads on your desktop.

Don't panic if you experience these; many factors can slow a Mac.

Checking for Viruses:

Avoid downloading and installing solutions from search results, as many are malware themselves.
