Web Site Zapper is a Windows 95/98/2000/ME/XP software program (does not work on NT) that closes Web browsers that are displaying undesirable Web sites. It can be used for several purposes: 1) Blocking your browser from being redirected to dangerous or undesirable sites, such as those infected with viruses. 2) Blocking popups 3) Access control, to allow parents, schools, and employers to prevent children, students, or employees from going to undesirable sites, such as pornography or gambling sites. 4) Controlling when people can access the Internet. Web Site Zapper has a password protected switch to turn off blocking, so you simply have Web Site Zapper block all Web sites until you are present and can turn off the blocking. Parents can use this to control how much time children spend on the Internet. With Web Site Zapper, you compile a list of good and bad Web site titles and/or URLs (Web addresses). You can add Web site titles and URLs to these lists manually, or have Web Site Zapper build these lists automatically in learning mode. Once you have built a list of Web sites, Web Site Zapper can operate in either of two modes. It can either close down any site on the bad site list (Block mode), or close down any site NOT on the good site list (Allow mode). You would use Block Mode if you want to allow general browsing, but block access to some objectionable sites. You would use Allow Mode if you want to restrict access to a few specific sites or subjects. The Allow mode is most common for businesses, where the work requires the employees to access certain sites, but the employers do not want the employees doing general Web surfing on company time.
