The Ultimate Guide to Checking for Viruses on Your Mac

Keeping your Mac free from viruses is essential for protecting your device and data. Viruses can damage your files, steal your personal information, or even take control of your computer. That’s why it’s important to know how to check for viruses on your Mac.

There are a few different ways to check for viruses on your Mac. One way is to use a third-party antivirus program.
