I'm back at this stage again; wondering the level of protection I really need. After anaylzing my daily tasks on the PC, given I don't deal with "cracked software", and I spend most of my browsing in Opera or FF. Till date, I have not had any infections pertaining to Viruses, Adaware, or Spyware. My current level of protection is Spywareblaster, SAS on demand. I have been a week without anything else as protection, but am thinking of using a lightweight firewall + hips. My intention is to have a very lightweight security setup that will be able to detect things such as malicious intentions when plugging in someone elses USB drive, or connecting to multiple wireless connections. Other than that, I don't worry about being infected. So my question to you all is: What would be a easy to use, effective and lightweight firewall to use for a laptop? Is threatfire(without an AV) the right choice when dealing with malicious intent as stated above? Note: I would like to avoid running an AV, so please don't suggest them. My new security setup is towards intended malicious attacks instead of infections from things 'I' do. Thanks.
