Query: I'm changing to McAfee

I had no complaint with Norton virus protection, but failed attempts to get the virus protection updates from Symantec, that I paid for, have ruined my opinion of the whole package. I e-mailed customer service for help, and was told I had to contact tech. support, who told me I would have to contact them by a long distance phone call if I wanted any help. My third e-mail to customer service was not answered. Symantec has become so large it no longer has time to help its customers, so I'll do my part by reducing their customer base.
