Firewall does not block traffic in "Block All" mode [NBZ]

The bug/issue

  1. What you did:

Bought a new machine, installed Win7 - and Comodo CIS first thing!
Then just browsing the net, using dropbox, skype etc.

  1. What actually happened or you actually saw:

I missed all the firewall alerts I was used to with XP. No icon animation (yellow carets).
Then I openend CIS and saw:
0 outbound connections
0 inbound connections
No traffic shown in the details pane.
Then I ticked “Block All Traffic” but Internet present like before.

  1. What you expected to happen or see:

Traffic shown by CIS
TRhen - after blocking all - Skype logging off and being unable to browse.

  1. How you tried to fix it & what happened:

I saw that Windows firewall was on.
Download latest CIS version.
Uninstall CIS, clean registry, turn off Windows firewall, reinstall CIS
CIS still doesn’t display connections or traffic.
CIS still doesn’t actually block traffic when told to do so.

  1. If its an application compatibility problem have you tried the application fixes here?:
  2. Details & exact version of any application (execpt CIS) involved with download link:
  3. Whether you can make the problem happen again, and if so exact steps to make it happen:
  4. Any other information (eg your guess regarding the cause, with reasons):

Have I caught a trojan which blocks firewall?

Thank you for your bug report in the required format.

Moved to verified.

Thank you


Meanwhile I tried to install Agnitum’s Outpost Security - with no luck at all. Their installation failed to load the kernel driver AFW.SYS.
Maybe a problem with some service which must run?

I found a crippled GigE-Camera-Network-Driver which wasn’t completely removed after a failed installation.
I uninstalled it in TCP/IP settings. Now Comodo is working again like a charm.
