Network blocked as "Malware"

Recommended Posts

I recently replaced my modem, and got a new dynamic IP address from my ISP.

I have a few servers on my network, running a few things I host locally (some used for services that a few remote devices connect to, most with Malwarebytes Premium running on them) and have hostnames that point to a dynamic DNS entry which gets updated when my IP address changes.

When that IP address changed, Malwarebytes suddenly started blocking the anything trying to access the IP address, because of "Malware".

It's definitely possible that the IP was used previously by someone who had a compromised network, or who was purposely sending out malware, but there's nothing on my network that should cause an issue.

I tried forcing a dynamic IP update, but then once my IP address changed, the new one was instantly blocked again with the same warning.

It's possible that Malwarebytes saw the machines trying to connect to that IP/hostname and thought it was suspicious and therefore blocked it, or that something was running on both of those IPs previously, but how can I find out why the IP was blocked, and how can I get it unblocked?

Thanks a lot!

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance

    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop

Hostname is still being blocked even with the new IP address on multiple machines, opened a ticket as well...

Issue is that there's no easy way to see why an IP/URL was blocked, and to request it be re-reviewed, like when an IP is dynamic and assigned to a new client...

Seems like it's an issue with something being blocked on the server end, but I have the logs from one machine, rather not upload them publicly, but I can send a link to download them, if that would help at all.

Thanks, wasn't sure how to narrow down the issue, hoping that will take care of it, though I'm still curious to understand how these things get blocked, and would love to see a public form where users could view why a site is blocked, and request removal...

Appreciate the response and help!

That's a forum, would like to see a form, similar to how SonicWall (use them for a bunch of our corporate offices and networks) lets you view the rating for a site (


) and also lets you submit a request to have the rating category changed (


), though it's obviously a different product and concept...

That is the key. That section is the fastest way to get a website/ip block checked and removed or to find out why it is blocked if a legitimate block.
