Antivirus activation is quick but the steps differ for every brand. First, a tip that applies to all of them: remove your old antivirus before installing the new one. Two antivirus programs running together slow your PC and cause errors.
Norton 360 Deluxe
- Sign in or create your account at norton.com.
- Choose to enter a product key, paste your 25-character key and follow the prompts.
- Download Norton and install it, then sign in inside the app with the same account.
McAfee Total Protection
- Go to mcafee.com/activate.
- Enter your key and your email address, then sign in or create an account.
- Download and install the McAfee app on your PC and sign in.
Kaspersky Standard
- Install Kaspersky from the official site (kaspersky.co.in or kaspersky.com).
- Open it, go to Licence and choose Activate with a code.
- Enter the activation code. Signing in to a My Kaspersky account lets you see and manage your licence later.
Avast and AVG
- Install the app from avast.com or avg.com.
- Open the app, go to Menu and look for Enter activation code.
- Paste the code and confirm. The status changes from Free to your paid plan.
Key not accepted?
- Type it exactly as sent. Letters like O and 0 can look alike. Copy and paste works best.
- Make sure you are activating the right product (a mobile key doesn't work on a PC app).
- Check the region or account. Some brands tie keys to the account where you first redeem them.
- Still stuck? Send us your order number on WhatsApp (+91 84097 62326).

Frequently asked questions
Can I reinstall my antivirus later?
Yes. Sign in with the same account and download it again. The licence stays valid until it expires.
Can I use one key on a phone and a PC?
Only if your plan covers multiple devices and platforms (for example Norton 360 Deluxe for several devices).
Do I need to uninstall the old antivirus?
Yes, remove it first. Windows Defender switches itself off automatically when another antivirus is active.
