Which Antivirus Offers the Best Protection in 2025?

McAfee vs Bitdefender vs Malwarebytes

When people talk about antivirus software in 2025, three names always come up: McAfee, Bitdefender, and Malwarebytes. Each has built a strong reputation over the past decade, and each appeals to a different type of user. Many buyers assume all antivirus tools are basically the same—but in reality, that’s far from true.

Security threats have evolved dramatically: ransomware, data-stealing trojans, phishing kits, crypto-stealers, webcam hijackers, and even AI-powered malware are now common. So the real questions are:

Which antivirus is strong enough for 2025?
