Hi Rahul, Your title above shows that you want to renew a subscription, but your message states that you simply want to activate a registered subscription. If you have already registered and received a confirmation from McAfee, contact them and ask how to activate.Make sure you have your account and product key available.
hi all, My new Dell laptop came up with Mcafee 15 months subscription.  I followed the link on the dell site to register with Mcafee - but not able to activate the subscription. Any help in this regard would be really appreciated.  Thanks in advance, Rahul
