Pros: - Can detect some known trojans which your antivirus or antispyware will not detect.
- Has a setting that you can adjust (1 through 5. 1 will allow everything through, while 5 will alert and ask you to block everything, including basic programs such as firefox).
- Unlike any firewall, it will literally block dead in its track any program before it can execute any code further.
- It's a free program that protects you against so many things, which will make you aware that a program is attempting to connect to the internet (better than any firewall in some cases, although it is a MUST to run a firewall. Having TF alongside any firewall is an excellent defense!)
- You can scan your pc for threats as well (but its strength lies more in blocking connectinons)
Cons: - Program is not receiving anymore database updates. However, their website still allows you to download Threatfire.
Other Thoughts: Despite not receiving anymore updates, this program is a MUST when defending your pc. Usually viruses will connect to a remote pc, but Threatfire will alert you if a file is trying to do that and block it (temporarily or permanently depending on whether you allow or reject it). I personally keep my setting on level 4, so that it alerts me of some attacks that might seem benign but would in fact be malignant.
