Look 'n' Stop Personal Firewall is a security application primarily used for protecting the computer from malicious software. The program's main feature is that it blocks Trojan Horses, which are viruses primarily used by hackers to transmit data from the infected computer to the hacker's database. If a hacker successfully hacks a computer, the Internet connection of the computer will be used to transmit data to the hacker's computer. Through this application, hacking can be prevented, as well as the presence of unwanted viruses on the computer.
Look 'n' Stop Personal Firewall also guards the computer from unique software called spyware. Spyware is a type of malicious software that displays unwanted advertisements on the user's desktop. The application can also guard against keystroke loggers. These kinds of programs detect what the user types on the keyboard, such as when inputting usernames and passwords. Through the application's log events, the user can track the hacking attempts to the computer and how many have there been in a certain period. An "anti-flood" feature in the log events lists down similar attacks in just one log, thereby saving space. The software has the option to run on the computer's system tray or in other locations specified by the user.
