Although they are excellent in their design, having a basic firewall by itself is not sufficient to provide hacker prevention. Detection firewall intrusion often takes place after the fact. An important note here would be that a firewall cannot remove things
that are already on your computer or network. If there was a virus before, or trojans, they will still be there afterwards. Which
brings up another point - the first thing that needs to be done, before installing any firewall or intrusion detection software, is to remove all malware from the system by using a good scanner and removal software program. At the present time, there are a number of them that are free. It might be a good idea to run more than one - but be sure to disable the one you are not using. Experience shows that different software will detect different malware.
When selecting your intrusion detection software, you need to know that there are basically two kinds. One is passive, meaning that an alarm will be sounded. A second kind is active, meaning that it will terminate the communication with the computer trying to obtain access, and it will notify the Webmaster. Intrusion detection software can also stop phishing emails, spam, and those pop-up ads. They can also prevent dial up hacker from invading your system.
