Could Symantec’s antivirus software guarding company, as well as government computers include a backdoor allowing hackers access to corporate data?

A new security vulnerability rated as highly severe by a security research firm, "has everything required for a worm," according to Mike Puterbaugh, vice president of marketing for eEye Digital Security.

Symantec security protects more than 200 million computers, according to the company. Symantec has also recently argued its software -- not Microsoft's – should be trusted to keep computers safe.

The flaw could impact users of Symantec AntiVirus Corporate Edition 10.0 and Symantec Client Security 3, according to eEye. The firm said the vulnerability can "compromise affected systems, allowing for the execution of malicious code with system level access."

Unlike some security glitches, which need a user to open an attachment, visit a Web site or click on something, the Symantec Antivirus flaw requires no user interaction, according to a security advisory posted on the eEye site.

In a posting to its Web site, Symantec described the reports as unverified.

"Symantec's Product Security team has confirmed that the reported vulnerability by eEye Digital does not affect its Norton brand," the company said, referring to its Norton line of security products such as firewalls and anti-virus updates.

Puterbaugh said eEye’s latest research confirms Norton products are not affected by the bug.
