We purchased a machine from China and it came with malware preinstalled

Talk to afraid.org, perhaps they'll take down the subdomain.

Bought a system on Ali Express to save money, the parts don't match what they ordered, it is infected with a virus designed to steal their data and infect executables on any USB device plugged into it to spread the infection. Ali Express says computers with viruses on them aren't against terms of service. They for some reason continue to use the system and try to get it to work.

£4k GBP...relatively low cost compared to a branded competitor...We sent the file for proper malware analysis which did confirm that it did indeed contain malware. The malware would collect user data and send it to a remote address.

I remember I bought a few phones from Aliexpress once for one of my IoT projects. I was somewhat surprised they don't really hide the malware, it's preinstalled. These are not just the usual bloatware you can't install but also the main web browser already modified injecting random crap.
