A bit late but...
quick comment for other toaster users (SC101)
New install of latest free version of "Comodo internet security" (3.5.5713.439), killed of the Netgear disks, but when firewall was disabled they came back .. i.e. it was Firewall not Defense+.. so after reading this thread,
I got mine going by
1: making Z-SANSERVICE.EXE a trusted application,
2: Creating a network zone "local" with ip range: (my local network) 192.168.1.1 - 192.168.1.255.
3: Running stealth ports wizard and selecting the new "local" zone I had just created.
4: Adding 20001 to the HTTP port set.
5: under Advanced -> "Attack Detection Settings" -> Miscellanious I un-ticked "Block Fragmented IP datagrams".
Each time I re-enabled the firewall as "Training" mode
i.e. the all same fixes as proposed in this thread, without all the safe mode uninstall / clean / reinstall.
I did the above in sequence, I have not removed any of the setting since, so I cannot say if all or only some of the settings are required, only that at each step I re-enabled the firewall, and each time the SC101 disk vanished, until point 5!
After point 5 I set the firewall as "Safe" mode and all is fine! :-)
thanks for a great product Comodo!
