Antivirus is non-negotiable for a PC. And while Windows’s built-in security is good, you can further increase your protection with an independent security suite—like Bitdefender, which is on sale in the PCWorld Software Store for just $22.50 during Black Friday week, or 78 percent off. 

This deal is for a Bitdefender Total Security 2026 5-device, 1-year subscription, which normally costs $110 per year through Bitdefender directly. If you need more devices or a longer subscription term, you can instead grab a 10-device, 1-year subscription for $40 (64 percent off) or a 5-device, 2-year subscription for $50 (68 percent off). These licenses are valid for US, UK, and EU residents.

Bitdefender Total Security’s strongest asset is its antivirus engine, which is better at catching malware than Windows and many rivals, too (as shown in tests from trusted security organizations like AV-Comparatives). But it also comes with other additional features, like a firewall with a modern, easy-to-navigate interface; a vulnerability scanner; and more robust parental controls. And it’s compatible with Android and macOS too, in addition to Windows.

Looking for more features? PCWorld’s software store is also offering a discount on Norton 360 Deluxe right now, with a 5-device, 15-month subscription going for $25 (76 percent off). It is marginally weaker at detecting malware and has less customizable parental controls, but in trade you get more features: a password manager, VPN service, and 50GB of cloud storage for backups.

You can check out our review of Bitdefender Total Security for the full rundown on what it’s like to use it. But don’t wait too long to do your research and make a decision—like all Black Friday deals, this is a limited-time deal and won’t last long!
