Both Malwarebytes and Sophos products leverage Windows Filtering Platform as part of the Web Protection feature. If a Windows machine has Sophos and Malwarebytes installed with Web Protection enabled in both products, a WFP network conflict occurs. This conflict produces internet connectivity issues on the machine such as:
- Long load times for web pages.
- Failure to load some web pages.
- Failure to run internet based applications.
For more information, see Microsoft's document on Windows Filtering Platform.
