Hi All,
there's a legacy piece of code trying to reach obsolete domain su2.ff.avast.com. It wasn't doing any harm up until recently as every DNS server should be reporting that domain as non-existent.

Note this response from Google DNS servers:
Code: [Select]
nslookup su2.ff.avast.com 8.8.8.8
Server:         8.8.8.8
Address:        8.8.8.8#53

** server can't find su2.ff.avast.com: NXDOMAIN

What seems to be happening is this. Some ISPs are possibly using this service www.barefruit.co.uk for returning custom (advertising?) content to many network related errors, like non-existent domains. And MBAM seems to start having issues with this content or a set of IP ranges, reporting it as a malware content.

We'll disable queries to this domain into the next available release which should resolve the problem with this particular non-existent domain. But the other part of the problem lies elsewhere, ISP serving custom content on invalid requests (DNS, HTTP) and MBAM reporting it as malware.

Regards.

The lastest version of Avast did not seem to fix this issue.   Once I switch back to Verizon dns the pop-ups re-occurred.

You don't say what version you have, as the latest version is now 10.4.2233 released, very recently.

Sorry guys, when I was posting my message, the version you're mentioning was already in testing stage and was closed for changes. So the fix will be in the next version, which will probably be (unless any super urgency occurs) Avast 2016.

Regards.

Good luck.... The problem is Malwarebytes not Avast .
I think the real problem ist that you shouldn't use 2 malware programs at the same time. One is enough. If somethink is really suspicious I send it to Virustotal or Jotti.

The rule is not to use two resident Antivirus programs at a time. :) Avast and Malwarebytes work well together

I use both Avast (with real time protection) and Malwarebytes free (only as a scanner) on the same machine, no problem.
Yes I use Virustotal and Jotti too, but they are for individual files, have file size limits, and I can't change any settings in their scanners.  Besides, what if you happen to be offline? :)

I use Avast (or another Tool) as real time protection and as a scanner. Think that's enough security; why use another program?

Because Malwarebytes is an excellent companion to any AV that includes Avast. :)
