I hope that this is the right place for this - if not, please feel free to move it to wherever is appropriate.
I have just updated Comodo to the latest version (3.11.108364.552) on two machines and the firewall has immediately blocked all outgoing connections from Explorer.exe! It has added a firewall rule to Explorer.exe to “Block And Log IP Out From IP Any To IP Any Where Protocol Is Any”. As this is the main Windows process, this seems somewhat drastic. I think Comodo did pop up a message about buffer overflows on one machine but I am not sure and I didn’t notice anything on the other.
Please will you check this out?
