How does that work when these types of viruses may compromise XP or Win7 systems? Are the viruses blocked at the corporate firewall?
At this point I'd hope that they're airgapped from production networks.
At my last job, they had Windows 2000, XP, Vista, 7, and 8 (before 8.1) all on the same network. And the highly trained managers would scream at us for not getting Outlook 2010 installed on A windows 2000 machine. Running a P3, and 256MB ram, with cute 20GB drives. Our CTO finally had enough and blocked the switch ports to Vista machines and back. He basically forced them to update to newer hardware/software. The only reason they still had these machines was because "they still run".
And I have come across companies with a blend of Server 2000-2016 hosts/vms. Some run some super important legacy programs, and others still exist because "upgrading costs money". Well...when the data is encrypted or lost because of these machines, that costs more than a server!
