How should you avoid it?

Firewalls and antivirus software can be very helpful when you are trying to avoid malware. Why? Antivirus softwares help because they have a list of viruses that can be caused by certain websites. When you try to go to one of these certain websites they don't allow you. Firewalls also are like that. They only let you in to websites that are safe.
