This is from a thread at the DSLR forums: The question raised was "At log-in screen - is your computer vulnerable?" and a member responded with - "Software firewalls like Look n Stop by default do not protect the computer until the user account starts up, and are a extreme risk to your system security." Can anyone comment on the veracity of this? Is there even a small period of vulnerability during boot or shutdown during which LnS (or another firewall) does not fully protect the system? I have LnS automatically starting with system and common to all users.
