God I hate this MBAM malicious site blocking, it is more a pain in the backside than a help.
- MBAM malicious website IP Detection reporting avastSvc.exe as process:
No avast isn't infected. MBAM isn't blocking avast as such, as the avastSvc.exe is the main avast service and it controls the various shields. The Web Shield routes all http traffic through its localhost proxy, so all MBAM sees is avastSvc.exe as the originating process, which is incorrect.
This is either you trying to connect to this IP via your browser or possibly a link in a site you're viewing redirecting of getting content from that IP address.
What site were you on when this alert occurred ?
