Avira ranks high overall for malware protection from third-party testing labs, though we discovered a couple issues during our testing of this program.

Panda Dome Advanced is considered an internet security suite rather than a basic antivirus program because it includes security programs beyond malware protections. These include parent controls, social media protections and safe banking tools.

Bitdefender Antivirus for Mac is our pick for the best Mac antivirus software because it offers solid protection for a fair price.
