Who wouldn't like that? (besides the individual companies that is)
If the companies like Norton, McAfee, NOD32, B i tdefender, Kaspersky, Trend Micro, and yes even mr. PandaSecurities all worked together to share definitions or even joined up, what a powerful team that would be.
Singularly, each company individually has flaws in their programs, but together they should dominate!
Similar to the merging of Checkpoint, Cisco, ZyXEL, and SonicWALL for firewall development.
