usb antivirus for Mac

Despite the accessibility and convenience of using wireless technology to transfer files from one computer to another, many of us still use external devices such as USB drives. Unfortunately, these are not always safe. To ensure the safety of your Mac when using external USB drives, you need to scan them first for possible virus infection.

That’s where the need for an effective USB antivirus for Mac comes in. We’ve rounded up the best USB antivirus software that you can use to scan to ensure that the USB drives that you use are safe and free of any viruses.

What is USB Antivirus Software and How Does It Work

Simply put, USB antivirus software is a type of virus protection program that lessens the chances of malicious attacks on computer systems coming from the use of external drives or devices. That includes USB drives. USB antivirus software identifies and blocks threats upon detecting them when you connect a USB storage device to your Mac.

Once it detects the virus, the software will contain it as normal antivirus software usually does. This all happens in the background and you won’t even notice it happening. USB antivirus programs usually come as an additional feature of your traditional antivirus software.
