Firewall security systems have been around in town for several years now. Yet the protection they provide can't be considered ancient. With the modern breed of viruses, hackers, spyware, and malware, device makers are continually upgrading the security products that they are selling. But I think there's one that's an exception to this statement: Kaspersky Anti-Hacker (KAH) firewall. Although it came from a company that makes good products, this one is a bit lousy than its predecessors.
KAH is included in Kaspersky Personal Security suite line, but it's not as great as the other products produced by the company. It protects the computer from attacks of hackers and blocks malicious programs from penetrating the system. Unlike other firewalls, this tool unfortunately does not have a database of legal programs. Thus, you still have to click a
tray icon to allow or stop access of a program. This means that you have to stay all night beside your computer to let every other program access your network. On the plus side, this product works at its best if you use it along with the whole Kaspersky suite. However, I honestly don't recommend this tool because there are far more better firewalls that can work on their own without disturbing us users.
