I've just started experimenting with the PRTG Network Monitor on my home network. I have a few sensor issues, I'll post them separately.
I have a Dell PC (Windows 10) with McAfee Anti-Virus, Anti-Spyware and Firewall installed. Everything appears to be running and up-to-date, but the McAfee Firewall sensor indicates 'Running - Out of Date'. The McAfee Anti-Virus and Anti-Spyware sensor is OK. As I said, I'm pretty new to this - do you have any suggestions?
