I just skimmed through the news. A lot of airports, hospitals, and even governments are down! It's ironic how people are putting their eggs in one basket, trying to avoid downtime caused by malware by relying on a company that put their system down. A lot of lessons will be learned after this for sure.
Unless you run half your devices on one security vendor and half on another surely there is no way round it? Companies install this stuff over "Windows Defender" so they can point fingers at the security vendor when they get hacked, this is the other side of the coin.
It has happened before where security software has unwanted effects, can't say i remember anyone else managing to blue screen Windows and require a safe mode boot to fix the endpoints though.
Relying on easy-install "security vendors" is the problem. It's one thing to run an antivirus on a general purpose PC that doesn't have a qualified human admin. But many of the computers affected here are single-purpose devices, which should operate with a different approach to security.
