HP and Symantec this week announced a multi-year extension that will ensure that all HP desktop, laptop and notebook PCs will be shipped with a free, 60-day subscription to Symantec's Norton Internet Security software suite.

Symantec (NASDAQ: SYMC) officials said the latest version of Norton Internet Security 2010 and Norton Antivirus 2010 include reputation-based security features that help identify, classify and validate files and applications running on consumer and corporate PCs.

The length and terms of the extension were not disclosed.

"We are pleased to continue our long-standing relationship with HP by providing our award-winning Norton products and quality online services to their desktop, laptop and netbook PC customers," Janice Chaffin, group president of Symantec's consumer business unit, said in a statement. "Through our valued partnership with HP, we are helping to keep consumers safe from cybercrime by offering superior online protection to millions of worldwide users straight from set-up."

Symantec, McAfee (NYSE: MFE) and a slew of smaller and mainly privately held security software vendors have enjoyed strong sales and profit growth in recent years as both the volume and sophistication of organized hacking and malware attacks has increased.

HP (NYSE: HPQ), which today also rolled out a series of new products aimed at locking down security risks in software development, said the Symantec extension will help drive sales to customers concerned about safeguarding their personal data.

"HP customers recognize Norton as a world leader in security solutions for PCs," said Jason Zajac, vice president of HP's personal systems group. "We believe customers will appreciate HP having pre-installed subscriptions to Norton Internet Security on PCs so they can get instant protection from online threats without having to download software."
