su2.ff.avast.com - Malicous Website Detected
« on: September 10, 2015, 12:10:57 AM »
Hello,

I thought I would post this here since Malwarebytes is blocking and reporting su2.ff.avast.com as a Malicous Website.

All scans are reporting clean.

This pops up every few minutes and just started today.

Thanks

For me the first thing I disable in MBAM Pro was the malicious sites as it doesn't do as it says on the tin - it notifies you on much more than malicious sites or rather it has many categories other than malicious sites included in its database.

AS you can see these are sub-domains of avast.com.

Please report it on the Malwarebytes forum.

It might not be a false positive, appears to related to a DNS hijacker if you read the post by MysteryFCM https://forums.malwarebytes.org/index.php?/topic/172525-su2ffavastcom-being-blocked/

It would seem that Avast needs to update its client-side software and/or server configuration to resolve this issue.  It's affecting a number of people (myself included) and it doesn't seem to be attributable to Malwarebytes.  Of course, if Avast disagrees that's fine, but I would ask that Avast take up the issue with Malwarebytes and come to an agreeable solution.  Each company telling all these people to contact the other company's support staff is a waste of everyone's time.  Thanks!

It looks like this is a DNS hijack as reported at Malwalebytes.

Many have changed their DNS which fixed the problem without disabling Malwarebytes.

Here is a link to change your DNS.

This started about four days ago for me. Resetting DNS to the Google settings seems to have fixed it for me. I am running Win 7 Pro, MWB Premium, Avast PRO and using Verizon FIOS.

Same Problem I am having. the MBAM forum states: the avast program is trying to make connections to "su2.ff.avast.com" but "su2.ff.avast.com" does not resolve to an IP address and, so, the connection is redirected to the "92.242.140.21" IP address which is flagged by the MBAM program. I tried to ping the address myself and it would not resolve.

I want someone from Avast to address this issue.  This is silly, the transmittal is coming from their system and is annoying.

I'm not from avast, but an avast user just like yourself - If this is DNS Hijacking as has been suggested on the malwarebytes forum, then this is somewhat different when saying who is at fault.

Are you aware what dns hijacking is, when your computer/browser tries to access a site that is shown in a user friendly/readable form such as su2.ff.avast.com it checks against 'your' DNS server commonly provided by your ISP to get the IP address.

If that DNS has been hijacked then it can return a different IP address, which could be considered malicious. But if it is your ISPs DNS server that has been hijacked then they have to resolve that. This is why not everyone is effected by this and why the suggestion to change your DNS server resolves this problem, when nothing has changed in avast.

So it isn't as clear cut as you might think.
