I work at a SOC and some non-PC devices like IP phones, and IP cameras have been sending malicious traffic to friendly clean PCs. I have searched google and their doesn't seem to be a remediation to scrub these type of devices. Had it been a malicious PC we would have had it re-imaged or put through a complete virus scan.

Anyway, I certainly look forward to your assist. Feel free to comment even if you don't have the answer.
