Only if the IP address is on its malware block list and MBAM would be alerting if it were and that isn’t mention that. The other problem is that MBAM free doesn’t have the Protection module enabled (which includes malicious site blocking) and that is what the OP is using.

So lets deal with the OPs problem, based on what they have installed.

Again I have no problem with MBAM Pro and avast updating on two systems and zero exclusions.
