sophos client firewall ndis packet filter

gary smith

Hi

Can someone confirm what the above is for exactly?  We have issues with internet speeds and the web filtering co requests we disabled/remove the driver.  I assume its part of the sophos firewall?

Thanks

    Hello gary smith,

    indeed scfndis.sys is the Sophos Client Firewall NDIS packet filter. Didn't SCF complain?

    So our web filtering software co recon there is a clash of this driver/application with their software.  I've uninstalled the firewall and web is still slow, so cant be the firewall..

    I am having this issue too.

    I have uninstalled Sophos completely (or think I have) and now on reboot I have a bunch of drivers coming up that are not 'installed' correctly or working correctly with the suffix of:

    "-Sophos Client Firewall NDIS Packet Filter"

    How do I get rid of these as my computer cannot connect to the local network wirelessly and I believe it is because of them.

    Hi Gary,

    I believe I've seen this before. Let me guess - you're using Windows 7? If yes - then we use LSP for intercepting traffic. 

    Can you confirm if this issue persists with Windows 8 or 10 devices? I will assume it won't as we use WFP. 

    Once we have more information on the table, I would comment further. 

    Thanks,
