20 Verified Brands | Nov 2026

In 2024, the US government banned sales of Kaspersky antivirus software, citing national security concerns, and the same year the US Federal Trade Commission ordered Avast to pay $16.5 million over selling users' browsing data. Both cases show that choosing security software means trusting the company behind it, not just its detection rates.

Built in protection has also improved, with Microsoft Defender included free in Windows. This category covers antivirus and security suites, from Norton, McAfee, Bitdefender, ESET, Avast, AVG, Avira, Trend Micro, Malwarebytes, TotalAV, Kaspersky and F Secure to Mac security from Intego, Indian brands Quick Heal and K7, and network tools such as GlassWire and Heimdal.

VPNs are in VPN & Privacy, and password managers in Password Managers.

Do you need paid antivirus?

Microsoft Defender scores well in independent tests and is enough for many home users who keep Windows updated and browse carefully. Paid suites add extras such as a VPN, password manager, identity monitoring and parental controls.

Buy a suite if you will use those extras. Otherwise, the built in protection plus good habits covers the basics.

Use independent test results

Independent labs such as AV TEST and AV Comparatives test antivirus products regularly for protection, performance impact and false alarms. Their results are more reliable than a vendor's own claims.

Watch out for auto renewal prices

Security suites often sell the first year at a large discount, then renew at a much higher price automatically. Check the renewal price and turn off auto renewal if you want to compare deals next year.

Brands that share an owner

Several well known brands belong to the same company. Norton, Avast, AVG and Avira are all part of Gen Digital, so they share much of their technology.

Mac and phone security

macOS includes built in protection, but Mac malware and adware exist, and tools such as Intego and Malwarebytes add another layer. On phones, keeping the operating system updated and installing apps only from official stores matter most.

Ransomware protection

Ransomware encrypts files and demands payment. Security suites include ransomware protection, but regular backups stored offline or in versioned cloud storage are the most reliable defense.

Security habits that matter most

Keep your operating system, browser and apps updated, since most attacks exploit known flaws. Use a password manager, turn on two factor authentication and be wary of unexpected links and attachments.

No antivirus can fully protect against a user who approves a malicious request.

Fake antivirus and scareware

Pop ups claiming your computer is infected and urging you to call a number or download a tool are scams. Close the browser tab, and only install security software from the vendor's official site.

Performance impact

Modern security software has little impact on most computers, but some suites slow older machines. Independent performance test results and free trials show the effect on your own computer.

Only run one real time antivirus

Running two real time antivirus programs can cause conflicts and slow your computer. When you install a third party suite, Windows usually turns Defender's real time scanning off automatically.

Identity theft protection

Some suites include identity monitoring, which alerts you if your email, passwords or other details appear in data breaches or on criminal marketplaces. Free services such as Have I Been Pwned offer basic breach alerts for email addresses.

Check what paid identity plans actually cover in your country, since insurance and restoration support vary widely.

Safe browsing and phishing protection

Browser extensions from security vendors warn about known phishing and malicious sites. Modern browsers include similar protection, such as Google Safe Browsing and Microsoft Defender SmartScreen, which is on by default.

What to do if you are infected

Disconnect from the internet, run a full scan with your security software, and use a second opinion scanner such as Malwarebytes. Change important passwords from a clean device, and restore from backup if files are damaged.

Security for small businesses

Businesses benefit from central management, device control and endpoint detection and response, found in business editions and tools such as Heimdal. Check the per device price and support options.

How many devices?

Plans cover a set number of devices across Windows, Mac, Android and iOS. Count the devices in your household, including family members' phones, before choosing.

When antivirus is cheapest

Security vendors discount heavily on Black Friday and Cyber Monday, and first year pricing is almost always discounted.

Making an antivirus coupon go further

Use coupons on multi year or multi device plans, which lower the cost per device per year. Compare the renewal price after the coupon period ends.
