Uh-oh, we're in trouble. Gotta get home quick, march on the double!

if you have to have one about the entire world, i learned you tire easily.

I understand and agree. Though I try to follow software news even if I'm unaffected, for a general judgement.

Any antivirus has to have a high clearance on your pc

I see. In that case I guess we can say this is a misuse of privileges, though concerning. Since they have the power to do this to any of their users. Not that they can pull the same thing in EU but what they did creates a risk, maybe they should've been more transparent about it. Being able to remotely install another software says they have more than high clearance in my opinion (I'm not a security expert). And yeah, Microsoft doing the same thing on OS level, but it's another topic.

yet Microsoft with it's billions still can't build a good anti pirate measure

I hear they got better comparing to Windows 7 days, but probably it isn't even close to third-party antivirus software.

Yeah, trust has become an issue with big corporations. For greater or evil reasons, they want more control over users. Either case they lose trust by doing that. A bit cliche but trust is hard to build and easy to lose. I think this is where Kaspersky is now, this might be bad for their reputation.

Things can even happen with one of the 50000 games on steam you install (and devs did install stuff with their "games").

I think this already happened and yeah can happen with any game, potentially. No idea if Valve has some kind of security measure for this, at least for obvious stuff. It's quite bad if they don't have any. Well, this is the exact same point. Trust.
