Do major antivirus companies really have the general population's best interest at mind??
They have business on their mind and a way to earn a lucrative income. No corporation conducts it's business solely for the best of the general population but for the best interest of their stockholders. Do they perpetuate their own business by introducing their own malware? I highly doubt that scenario.

The ones that actually look for the loopholes do it mainly for profit. Although I do remember many years ago,
that it was considered cool to crash some ones computer. ;D
