Shareware Programs for Computer Security and access control
Web
Site Zapper (wszarc.exe) - A
Windows Internet security
program that gives you control over what Web pages can be viewed on
your computer, allowing you to control
Web access. Web Site Zapper will block
Web sites by redirecting and then closing down Web browsers that
are showing undesirable sites, providing you with Internet
access control. You can either create a list of undesirable sites
(including broad descriptions like any site containing "gambling"
in the title or URL) or create a list of allowed sites (like your
business sites) that you want to allow people access to. Web Site
Zapper is useful in business to prevent
employees from surfing the Web on company time and at home to
protect children from hazardous sites. For more information, click

number of these programs have no way of stopping the employees from
changing the computer clock before punching in or out. It can also be
