A hacker said on Friday it would release the source code of the Norton antivirus software, Symantec, citing a case that was filed against the company.

The message appeared on the Twitter page Yama Tough, and said that the code would be revealed “today”-Friday.

Symantec said this week that hackers had stolen a big chunk of the source code of a third party involved who had access to it, although he said the company’s own network had not been violated. The company described the source code as the old one.

The company spokesman Cris Paden said on Friday that Symantec had no information, “particularly on any allegations that the group Anonymous is doing.”

A legal action filed in the United States earlier this week Symantec accuses of seeking to persuade customers to buy their products to frighten them with false information about the condition of their computers. The process described the Norton Utilities as a way to “program of fear.”

Symantec claims not to believe that the process has merit, and will vigorously defend itself.
