#5 Couples or small families on a budget
£12.99
It works for small families. But it’s rough around the edges.
Stop buying antivirus based on brand loyalty. Match the protection to how you actually live online.
Bitdefender Total Security wins for most people. It catches threats without slowing your computer down. The cross-platform support works on Macs, PCs, and phones, unlike many competitors. It doesn’t nag you with scary pop-ups. That makes it feel like a tool, not a pest.
Norton 360 Advanced is the heavy hitter for big families. It’s slightly heavier on system resources than Bitdefender. But you get identity theft protection and a strong VPN in one bundle. Ten gadgets? The per-device cost is fair. Just deal with the cluttered dashboard.
McAfee Total Protection is your budget option. It’s not lightweight, but it handles the basics. The aggressive upselling inside the app is annoying. Still, at £9.99, it’s hard to beat for simple safety.
An antivirus shouldn’t feel like a tax on your hardware. Bitdefender wins on efficiency. It barely touches your CPU, whether idle or scanning.
You won’t even know it’s there.
Norton and McAfee are clunkier. Norton’s heavy scans cause real lag. Gamers and editors will feel that frame rate drop immediately. McAfee is mediocre, offering less polish than either rival.
False positives matter more than you think. Bitdefender leaves your legit apps alone. Norton constantly nags you to whitelist niche tools. That friction is annoying and unnecessary.
Don’t let security software slow you down.
McAfee looks cheap at £9.99, but that’s just bait for one device. Try adding family members and the price balloons fast. It’s fine for a lone student, but a trap for anyone else.
Norton Deluxe wins for most households. Five devices for £12.05 means you’re getting solid protection plus a VPN and cloud backup without hidden fees. The math is hard to argue with.
Bitdefender costs nearly £20 for the same five-device limit. You’re buying speed and a slick interface, not just security. If your laptop slows down when you open a browser, pay up.
Otherwise, save your cash.
The real question isn’t which antivirus is "best." It’s whether you’ll notice the difference on your specific machine. For basic browsing, Norton does the job. Don’t overpay for performance you can’t feel.
Bitdefender wins on speed. It barely touches your system, so it’s perfect for older laptops or gaming rigs that need every cycle. Norton goes the other way. If you have a modern PC, Norton’s extra perks—like identity theft coverage and a solid VPN—are actually worth the heavier load. Pick based on your hardware, not just the brand name.
Norton and McAfee bundle VPNs into their top plans. Bitdefender does too, but watch out for data caps. It’s not always unlimited. Read the fine print on your subscription. You might think you’re covered, but you could still hit a wall. Don’t assume it’s all included.
Bitdefender and Norton cover everything. Windows, Mac, iOS, Android. One subscription. McAfee does it too. But don’t mess this up. Grab the right version for each gadget. Wrong installer means no protection.
