WinLock Professional is a powerful security solution designed to help you protect your computer against unauthorized use. This is an all-in-one tool that enables you to control various security-related aspects of Windows and configure access permissions on a very low level.

It offers all features of WinLock, plus several advanced features of interest to the power users and computer administrators:

• Apply different restrictions on a per account basis. Now you can create different protection schemes for each user account in a multiple-user environment. For each user, WinLock will activate only the selected restrictions. Moreover, it is possible to suspend all forms of WinLock protection for the specified user.

• Internet-related restrictions. WinLock Professional provides you with a group of selected Internet Explorer policies and enhanced content filtration suited to control and protect Internet access.

• Parental control and website content filtration. The Professional edition not only checks the address of the site, but also scans the entire page, including the hidden meta-tags for any prohibited words. For example, if you define "sex" as a keyword, any website contains this word will be prohibited. This makes possible to prohibit access to questionable websites - notably for public-access computers in schools and libraries. Alternatively, you can limit access to only the websites that you specify. In that case, your kids will only be able to access these sites, and all others will be off-limits.

• Onscreen countdown timer. Displays the remaining time on digital clock display.

• Built-in file encryption. You are likely to have confidential documents on your computer, which you may want to encrypt. LockBox Wizard will help you to protect any information. It uses a very strong Blowfish crypto-algorithm. Protected files cannot be decrypted without the correct password.
