Do you need paid antivirus, or is Windows Defender enough?
For one updated Windows 11 PC, free Microsoft Defender is enough. It blocked 99.0% of live attacks at AV-Comparatives, with zero false alarms. Windows 10 home PCs no longer get Windows security fixes, so upgrade if you can. A paid suite helps with phones and a Mac, children, online banking or an old PC.
Stay with free Microsoft Defender if:
- You use one Windows 11 PC and install updates promptly.
- You already use a password manager and don't need cloud backup.
Pay for a suite if:
- You want one plan for phones or a Mac too. Defender covers Windows only.
- Children use the PC, and you want parental controls.
- You bank online often and want a protected browser for payments.
- Your PC is old. Defender scored 13.5 on AV-Comparatives' slowdown scale, against 3.1 to 3.3 for McAfee, K7 and Kaspersky.
- You want cloud backup, or alerts if your personal details leak online.
How does each antivirus score in AV-TEST and AV-Comparatives?

*AV-TEST rated Norton 360, AV-Comparatives Norton AntiVirus Plus.
- AV-TEST's protection and performance scores, out of 6, show how much malware a product stopped and how little it slowed everyday tasks. See the AV-TEST August 2026 report.
- The real-world protection rate is the share of 400 live attacks from harmful websites and downloads that each product stopped. Defender missed 4 and Quick Heal 32, says the AV-Comparatives Real-World Protection Test.
- False alarms (false positives) are safe websites or files wrongly blocked. AV-Comparatives puts the average for the products in its test at 8.
- The impact score shows how much each antivirus slowed a Core i7 PC. Lower is better, says the AV-Comparatives Performance Test, September 2026.
How much does antivirus cost in India in year one and year two?

| Antivirus | Amazon.in key | Per device a year (Amazon.in) | Maker's store, year one | Maker's store, year two | Refund window (maker's store) |

- Amazon.in keys do not renew by themselves. You buy a fresh key each year at that year's price. Third-party sellers email the keys, which work only on an internet connection in India, and the Bitdefender, Kaspersky and Quick Heal listings rule out returns.
- Makers' stores renew automatically, so turn off auto-renewal if you plan to buy keys.
Best antivirus for PC overall: Bitdefender Total Security
Bitdefender Total Security (3 devices, 1 year)
6/6 at AV-TEST, 99.5% real-world, and about ₹189 per device a year.
~₹568Amazon.in
Check price →A paid suite at around ₹568 for 3 devices for one year, rated 4.4 by 589 buyers. One key covers any mix of Windows, Mac, Android and iOS devices, about ₹189 each.
It scored 6/6 for protection and 6/6 for performance at AV-TEST (August 2026), and blocked 99.5% of live attacks at AV-Comparatives (February to May 2026), with 5 false alarms.
The listing includes Safe Online Banking, parental controls and webcam protection. Its VPN, which hides your browsing on public Wi-Fi, stops at 200 MB a day. For a full VPN, see our NordVPN for PC guide.
Good:
- Top lab marks for about ₹189 per device.
- Safe Online Banking for payments.
Not so good:
- Bitdefender's own store renews its 5-device plan at ₹6,599 a year, about ₹1,320 per device.
- A third-party seller, TechEzy, sends the key, and you can't return it.
Skip it if you have one Windows PC and Defender already runs well on it.
Best free antivirus for PC: Microsoft Defender
Free, with no renewal fee, on any Windows 11 or 10 PC. Microsoft builds it into Windows, the only platform it covers.
It scored 6/6 for protection and 5.5/6 for performance at AV-TEST (August 2026), stopping all 297 zero-day attacks, which use brand-new malware. At AV-Comparatives (February to May 2026), it blocked 99.0% with zero false alarms, the fewest here.
Speed is its weak spot, with an impact score of 13.5. Defender switches itself off when you install another antivirus, says Microsoft.
Windows 10 support ended on 14 October 2025, and the paid extension for home PCs ended on 13 October 2026, so Windows 10 itself doesn't get new security fixes. Microsoft will still update Defender against new malware through October 2028.
Good:
- Free, already on and with zero false alarms.
- Controlled folder access guards your main folders against ransomware, malware that locks files for money.
Not so good:
- You must switch on Controlled folder access yourself in Windows Security.
- Windows only, with no password manager or parental controls in the app.
Skip it if your PC is old and slow, or you need one plan for phones too.
Best budget antivirus for PC: K7 Total Security

~₹385Amazon.in

Good:
- The lowest price here for full AV-TEST marks.
- Light on the PC, with a 30-day refund window on K7's store.

Skip it if you often install little-known software and want few false alarms.

Skip it if you need just one PC protected.
Best antivirus for an older or slower laptop: McAfee Total Protection
McAfee Total Protection (1 device, 1 year)

~₹799Amazon.in
Check price →A paid suite at around ₹799 for 1 device for one year, rated 4.3 by 6,072 buyers. It works on Windows, Mac, Android and iOS. McAfee's store also charges ₹799 for year one, then ₹1,499 a year.

Best antivirus for top lab protection: Kaspersky Premium
Kaspersky Premium (1 device, 1 year)
99.8% real-world protection, the highest rate among these picks.
~₹499Amazon.in
Check price →A paid suite at around ₹499 for 1 device for one year, rated 4.4 by 14,660 buyers, though Amazon.in seems to combine these ratings with the 3-device version. It covers Windows, Mac, Android and iOS. Kaspersky's store charges ₹689, then ₹1,166 a year.
It blocked 99.8% of live attacks at AV-Comparatives (February to May 2026), the highest rate here, missing 1 of 400. It also scored 6/6 for protection and 6/6 for performance at AV-TEST (August 2026).
The US Commerce Department banned Kaspersky software sales in the United States in June 2024 on national security grounds, says its press release. Kaspersky still sells in India.
Good:
- The best protection rate here, with a light impact score.
- Payment protection and a password manager, says the listing.
Not so good:
- One device per key.
- The key works only on an internet connection in India, and you can't return it.
Skip it if the US ban worries you. Bitdefender scores close behind.
Best antivirus for Aadhaar and PAN leak alerts: Quick Heal Total Security
Quick Heal Total Security (1 PC, 1 year)
Dark web alerts for Aadhaar and PAN, but 92.0% real-world protection.
~₹1,181Amazon.in
Check price →A paid suite at around ₹1,181 for 1 PC for one year, rated 4.4 by 5,792 buyers. It runs on Windows only. Quick Heal's store charges ₹1,591, and an Amazon.in renewal pack costs around ₹864.

Good:
- Alerts for Aadhaar and PAN leaks, says Quick Heal.
- Renewal packs cost less than new keys.
Not so good:
- 92.0% protection, below free Defender's 99.0%, and you can't return the key.
- Needs 4 GB of RAM or more, says the listing, and slowed the lab PC more than any of our other picks.
Skip it if lab protection matters more to you than ID leak alerts.
What about ESET, Avast, AVG and Net Protector?
We left these out after checking their lab results and listings on 14 November.
- ESET HOME Security Essential, around ₹550 and rated 4.4 by 1,789 buyers on Amazon.in, had 2 false alarms but blocked the same 98.5% as K7, which costs less.
- Avast Free and AVG Free blocked 99.3%. In 2024, the US FTC ordered Avast to pay $16.5 million over charges that it sold users' browsing data.
- Net Protector (NPAV) is a popular search, but neither lab's latest reports include it.
What to check before you buy antivirus for your PC
- Lab results, with dates. Look for 6/6 protection and performance at AV-TEST and 98% or more real-world protection at AV-Comparatives.
- Devices and platforms. Count every laptop, phone and Mac. Defender, K7 and Quick Heal cover Windows only.
- First-year and renewal price. Makers' stores renew at up to about ₹1,500 per device a year. Amazon.in keys never renew by themselves.
- Free or paid. Free Defender is enough for one updated Windows 11 PC.
- Price. These picks cost ₹0 to around ₹1,181 in year one.
- Refunds. Makers' stores give 30 to 60 days, but you can't return some Amazon.in keys.
Which antivirus should you buy?
For one updated Windows 11 PC, keep free Microsoft Defender. To cover more devices, buy Bitdefender Total Security at around ₹568 for 3 devices. On a tight budget, K7 Total Security costs around ₹385.
