But with all things, there is also the dark side, which when it comes to the Internet are viruses that roam the net and infect millions of computers.

There are three kinds of virus: those that are annoying, those that steal your personal  information and those that damage the operating system. All three take advantage of the fact that the user might not know what they are doing.

The antivirus is essential. The best defense against viruses is to have an antivirus installed in you computer and update it regularly. There are many free antivirus out there, so you don't need to pay a lot.

Make sure to also be careful with attachments and opening mails from unknown senders. Viruses can also be obtained by downloading programs you don't know much about. Before doing any of this, make sure to analyze the attachments and programs with the antivirus you have installed.

We can't stress enough ow important it is to not open emails from people you don't know. Don't do it! Most viruses come in email form, so be warned.

To protect yourself, make sure to back up your computer every couple days. Imagine if you didn't and you ended up losing all you photos, schoolwork and music!
