Computer hacker Yama Tough yesterday threatened to release the full source code for Symantec Corp’s flagship Norton AntiVirus software.

Yama Tough posted via Twitter: “This coming Tuesday behold the full Norton AntiVirus 1,7Gb src, the rest will follow.”

In the past week Yama Tough has released fragments of source code from Symantec products along with a cache of emails.

The hacker says all the data was taken from Indian government servers.

Symantec Corp described the stolen source code as several years old, Fox News reported.

A spokesman for the company, Cris Paden, told Fox News that Symantec didn’t have any other information, “particularly with regards to any new claims Anonymous is making”.

The company also had a lawsuit filed against it in the U.S. earlier in the week, accusing Symantec of encouraging customers to buy their product with scare tactics.

The suit claims the company issues misleading information about the health of their computers in order to persuade them into buying the software.

Symantec deny the allegations.
