We are seeing an issue when upgrading version via the SEC. It appears that the Sophos Client Firewall driver (scfins.inf) isn't signed. This has been confirmed by Sophos as I have placed a ticket with support. This happens on Windows 7 (32-bit) machines when upgrading from 2.5 to 2.7. Things we have done to try and correct this issue are increasing the MaxNumFilters from the Windows default of 8 to 10 which was suggested by Sophos. I have also tried configuring Windows to allow unsigned drivers to install by editing the Non-Driver Signing registry key. I was just wondering if anyone else is seeing this issue and if so if they've been able to resolve.
