Norton or McAfee annual fee auto charged - how to cancel ?

You have to contact McAfee/Symantec (who owns Norton).  For all they know, your computer is turned off and you're on vacation UNLESS you call them.  You (the user) probably had to setup an account with them in the beginning - you should be able to log in to that account and disable auto-billing. Once billed, I'm 99% certain McAfee/Symantec will have to issue you a refund.  You COULD call the credit card company and dispute the charge but odds are you'd lose the dispute because you wouldn't have notified the company charging you and the company charging you would have record that you AGREED to their terms (whether you read them is another story, but unimportant from this perspective).

Call Macafee and Symantec and cancel the subscription. There should be a link in each app to log into the wite and update the account. I'd do that and cancel the account. If you have been chanrged and want a refund, i'd send them an email from that link, call if necessary and then call the credit card company and say the subscription renewal was not approved and you want to dispute the charges.

If the employee is no longer employed at your company, include that information and cancel each account after you have the refund to make sure it does not continue to happen.
