Hope you will like it
karpersky internet security 2012 (not the antivirus security) have firewall too, it have 30 days trial subscription too. Rescue disk, isolation folder (can run suspected files in tht folder without causing damage to other system (atleast it is the function of that folder but i never tried that
oh but i think that it do not support boot time scan
i use it as a free av beacause of a hidden feature (check pm)
it crashes too, but only sometimes (rarely)
