According to reports by CNet, at least four leading anti-virus software developers have no intention to voluntarily modify their products to give the FBI a back-door for its Magic Lantern project.

The FBI confirmed on Wednesday that it is working on the controversial Magic Lantern project which will be used to eavesdrop on computer communications.

It is a program carried by a trojan horse, being e-mailed by the FBI to suspected criminals in the same way that viruses are often sent. Such programs, when unwittingly activated by a recipient, can record every keystroke by the individual and then e-mail the results to the FBI. This can give the FBI access to passwords or other information that is otherwise difficult to obtain.

CNet quotes officials at anti-virus developers Symnatec, Network Associates, Trend Micro and Sophos, saying they do not intend to compromise the security of their products. However, if the companies cannot obtain a copy of Magic Lantern, they may be unable to protect their customers against it.
