MWB keeps telling me that it blocked a website on port 3389? but I blocked

[robdob]

Hi,

 

I have MWB loaded on Windows Server 2012 R2

MWB keeps giving me the following message:

 

 

I have already blocked all TCP and UDP traffic to RDP port 3389 from all ip but one..  

 

Can someone please tell me what to do?  is this possible a false positive or is MWB blocking it before the windows firewall is actually getting a chance to block it..

 

here is my WFW:

 

 

here is a copy of my MWB event as per the issue above:

Lets address your initial issue first.

The attempts on various ports are tried by bots.   But they are STOPPED  by the Malwarebytes real-time web protection.

Malwarebytes is protecting your system.

See this article  https://support.malwarebytes.com/hc/en-us/articles/360048565893-Receiving-message-Website-blocked-due-to-compromise

 

In most cases the attempted probes will eventually stop on their own. If it continues you can add the IP to the local firewall to prevent it from contacting the computer period.
If you wish to do so, here is one how-to guide for the Windows software firewall
https://www.interserver.net/tips/kb/add-ip-address-windows-firewall/

 

Additionally or alternatively, if this is on Windows 10 PRO  and if you do not need or use Remote Desktop,  you can turn that off.

Hello,

 

Thank you for the speedy replay,  I have a question I have blocked both TCP and UDP port 3389 access using the Server 2012 R2 windows firewall from all ips except one ip which I use.. So I'm very confused why MWB is also blocking an attempt from outside.  Is MWB intercepting the netwwork traffic before the windows firewall is seeing and stopping it?

 

thanks in advance.

The Web Protection in Malwarebytes and the Windows Firewall in Windows 10 both use the same WFP framework/APIs, so they're essentially on the same level of the network stack, so to prevent the blocks in Malwarebytes you'd likely need to block it at the access point/router level.
