I'm not much of a network and network security expert, but I need to add an existing Windows PC to a network with always on connection.

The problem is, I have no idea if the PC is really clean, and, actually, no knowledge to check it.

I scanned the PC with Process Explorer to verify if all running processes are signed, ran an AVG scan, but this is where my knowledge ends.

IIRC, there can be bad code attached to svchost or something, bad drivers, and so on, but I have no idea how to check all those things.

Reformatting the PC is unfeasible as of now. Are there any suggestions on what I could do?
