Re: Ah, Microsoft
Exactly, and it isn't as if, say, oh, I don't know, Google, Apple or Linux distros has never been caught with their trousers around their ankles, by letting malware into their app stores/repositories, for example.
Given the limitations of AI checks, the limited number of human resources than can be thrown at the problem and the sheer quantity of submissions, none of these systems or programmes can be 100% fool-proof. It is how, and how quickly, they react, when a problem is recognised that is more important.
(For the record, I use an Android phone, a company iPhone, an iPad and several Windows and Linux PCs, so I'm not trying to excuse Microsoft for letting this in in the first place, or get at Apple, Google et al.)
