PC - not accepting multicast

Hi.
I've noticed my PC has stopped receiving multicast traffic.
If I boot into safe mode with networking then my application does get multicast..

I've disabled ZoneAlarm and Avast and neither of these have made a difference..

Any ideas what to try next ?

Thanks

You could try the Clean boot approach to troubleshoot the problem.

Thanks for the reply.
I removed ZA and Avast and still had the issue, so I put them both back, rebooted and now it's working !

No idea why but its fine again..
