The product, in beta from today, replaces well-known and trusted products like Norton Antivirus, Norton Internet Security and Norton 360, among others.
Norton Security will cost $79 a year in North America when it launches there 23 September; an Australian release date has yet to be announced.
The news means there won't be a new version of Norton Antivirus for the first time since 1991. The company announced there will be discounts for current customers, however, and nobody who's using an existing product will be forced onto a Norton Security plan right away.
"We're headed towards security as a service," Gerry Egan, Norton's senior director of product management at Symantec, said in an interview, adding Symantec is moving towards a Netflix-style subscription model, for security.
In a bid to ease users into the new product, Symantec also said it is introducing a money-back guarantee. If a Norton Security customer gets a virus and it can't be removed either through software or with the help of a tech-support rep, the company will issue a refund.
"We're kind of catching up with our customers," said Fran Rosch,vice president of Norton's business unit. "When they call in and we ask them 'Which Norton product do you have?' they always just say 'I have Norton.'"
The company got rid of its previous CEO, Steve Bennett, in March, as part of a restructure. Michael Brown has been serving as interim CEO and Symantec says it will announce its new CEO in September.
