These slides will show you how to install and use an Anti-Virus app on your Android Device.
There are two anti-virus apps I would recommend. The slide show above shows you how to install and use the basics for Avast. Kaspersky is also a very good anti-virus app.
Do you need one? I believe you do. Virus infections on the Internet are common and you need make sure your device is protected. Both of these apps have free versions, which work perfectly. You are more secure with an anti-virus than without.
