Internet Password Lock

    Internet Password Lock is a Windows software program that allows you to block, control and restrict Internet access. This includes Web browsing and surfing, Instant Messaging, and email. Parents can use Internet Password Lock to protect your children by making sure children do not use the Internet without a parent present. Businesses can use Internet Password Lock to lock out unauthorized Internet use and save money by preventing employees from wasting time on the Internet.

    Once Internet Password Lock is installed, all Internet access will be blocked when Windows starts. To access the Internet, you must view the main Internet Password Lock screen by clicking on the Internet Password Lock icon on the system tray and then input a password (selected by you when you install Internet Password Lock). You can then access the Internet freely until you lock the Internet again using Internet Password Lock.

    Internet Password Lock is available as shareware ($20 individual fee. Volume discounts available. For information on volume discounts, click here.). Try it for a month to see if you like it before you have to pay for it. Just download the install file to your computer, then run the file like a program by double-clicking on the install file in Windows Explorer or My Computer to install Internet Password Lock. Remember that complete instructions are provided for uninstalling Internet Password Lock if you decide that you do not like it.

Web Site Zapper

     Web Site Zapper is a Windows 95/98/2000/ME/XP/Vista/Windows 7 software program (does not work on NT) that closes or redirects Web browsers that are displaying undesirable Web sites. That is, when people go to an undesirable Web site, Web Site Zapper can either close down the browser entirely or it can redirect the browser to a page you select. 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 (explained  in the instruction manual).

     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.

      Titles and URLs on the lists can be very general. For example, you can block any site whose title contains "gambling" or "casino". You can allow any site whose title contains your company name. Likewise, URLs can be broad, such as allowing any URL that contains "". This allows you to easily set broad parameters for good and bad sites if you like. If you prefer, you can make the good and bad site titles and URLs as specific as you like.

    Web Site Zapper is available as shareware for $25 individual fee, with volume discounts available. (For information on volume discounts, click here.). Try it for a month to see if you like it before you have to pay for it. Just download the install file to your computer, then run the file like a program by double-clicking on the install file in Windows Explorer or My Computer to install Web Site Zapper. Remember that complete instructions are provided for uninstalling Web Site Zapper if you decide that you do not like it. Web Site Zapper runs on Windows 95/98/2000/XP/ME/Vista/Windows 7 (does not work on NT).

The following is an unsolicited testimonial about Web Site Zapper.

"Kudos on the Web Site Zapper program by Leithauser Research! The program was exactly what we needed for our client's tradeshow. The program is simple to use, doesn't have a lot of needless features and works perfectly. Web Site Zapper allowed us to lock down Kiosk Stations to direct all traffic to our client's websites only. The systems were set up to default to a custom screen saver when not in use, but prevented the public from accessing other websites and general search engines. Web Site Zapper even allowed the client's personnel to access password protected areas, but prevented all redirects to external websites. We were very happy with the program and will use it again when clients need to set up Kiosks on a tradeshow floor. I highly recommend Web Site Zapper, it's a great tool and a good value."
