WebSite Blocker is a network software that can block ads and adult materials. There are several reasons why websites should be blocked. It’s not uncommon for unsavory websites to carry malicious software that could damage your machine or infiltrate your personal information. Website Blocker prevents this by blocking these websites from being accessed. One problem with this program, however, is that it’s unclear how it updates its database. There does not seem to be any options to do this. That said, if you happen to find the website that you want blocked from your PC in the software, go ahead and use it.
