MBAM blocking normal processes again?

[louanna27]

Given the awful mess of a few weeks ago with MBAM going nuts over lawful processes, I've had three events today of the same nature:

I'm only going to usual websites and doing usual tasks.

Is there a reason for concern?

Thanks.

This will be unblocked on the next update.

Yes, I've been seeing IP addresses of the form 64.208.138.### with access attempts from high-level ports (49940,49953,49745,58295, etc) blocked my MWB Pro as well on several of my computers. I did some research and these IP addresses appear to trace back to an Internet advertising organization (names Level 3 Communications, Appnexus, Inc. and Adnexus) out of New York, ostensibly. I'm guessing these are attempts at popup ads which MWB is blocking. Are these legitimately "bad" sites? I'm fine with MWB blocking ANY popups, anyway; that's one reason I'm a big fan! I'm just curious since these warnings all started appearing today and they seem to popup from various unrelated sites from all kinds of genres.

Thank you for responding.

It's out of my league when it comes to "high-level ports" as mentioned by Blackberry445, but his comment seems logical.

Any comment please?

The block was in place due to malvertisements (malicious adverts), these are no longer present, hence the block now being removed. Update should be out shortly.

Mystery, so are you saying that the AppNexus IP is no longer blocked (which IP was it)? The ads weren't malicious, but some had toolbars..
