Internet is a very useful tool. It allows to spend a good time thanks to online games. Internet encyclopedias can help us at school. There are also many websites, which allow us to earn money. Internet also allows us to communicate with other people. One of the best methods of communication are e-mail messages. They are better than traditional mail, because we can send and receive them very fast. After a few minutes our mail will reach the receiver’s inbox.
Unfortunately many e-mails are full of unwanted ads, which are called spam. These mails can also contain viruses and other dangerous programs. We should find a program that will help us to avoid spam. This kind of program is called a web filter. It will scan our electronic mailbox and block suspicious messages. We can also create a list of dangerous senders and words, which are present in spam e-mails.
Url filtering is also connected with blocking suspicious websites, so we can feel safe while browsing the net. Thanks to it we will avoid problems presented above.
We can find Web filtering applications in computer shops and in the internet. We can buy them in a few minutes thanks to the internet banking and wallets (paypal, alertpay or credit cards). There are also some websites, which are offering basic programs for free.
