Problem: Symantec yell about how they loose loads of business if MS patch up their OS to make it secure.
Solution: Shut down or downsize Symantec.
Seriously, if they're saying MS should be made to sell a flawed OS for their benefit they should be laughed out of court.
That's like saying Ford needs to sell cars with crap parts so garages get more trade. Ludicrous.
Edit: I've noticed this post is actually kinda off topic... and possibly inaccurate. But I'm gonna leave it here 'cos it does apply to the MS Vs AV companies thing :)
