From the developer: "TrojanShield will prevent hackers from breaking into your computer. If a hacker tries to break into your computer, TrojanShield will intercept the attempt and notify you immediately. TrojanShield will then allow you to take action against the hacker. TrojanShield is very user-friendly and can be operated by anyone, but still offers the functionality required by expert users. With TrojanShield you can use the Internet with the reassurance that your computer and data are safe from hackers."
