What does it mean when I get an IP alert about blocking a 'malicious' site?

The Malwarebytes Anti-Malware web protection is typically activated when a website loads your browser and links embedded attempt to access an IP range which our research has found to deliver malicious content to users when they access a website which is on the IP range indicated. If the alerts only appear when you are surfing with a browser open then the possible trigger is a banner ad.


Users who run peer-to-peer(P2P) programs will see these alerts frequently. Due to the heavy amount of malicious content on these networks we block most by default, until cleaned of all threats.


In most cases nothing need be done, our protection has blocked the threat from infecting you.


SKYPE users see the links below about these IP alerts:

If you get the alerts while no browser is open and there are multiple IPs listed, this may be cause for alarm as the system may be compromised. In this case you should submit a request for support to have the system checked out. You can do that via the link below:
