Four major antivirus firms have all said that they will not cooperate with the FBI by leaving a backdoor in their programs which would leave customers vulnerable to the FBI's 'Magic Lantern' keylogging virus. The FBI has not requested this yet.
"We're in the business of providing a virus-free environment for our users and we're not going to do anything to compromise that security," Network Associates said. "If you leave the weakness for the FBI, you leave it for everybody," experts agreed.
Leaving a vulnerability would also weaken their attractiveness in foreign markets. "If (the Chinese) thought that the company was a tool of the CIA, China would stop using those products," the author of the VMyths website says.
