How to stay safe: Don't fall for phone calls that tell you your software

or computer isn't working. Never give your personal information like

together to perform a task. Botnets gain access to your machine

through some piece of malicious coding. Once the software is

downloaded, the botnet will now contact its master computer and let it

know that everything is ready to go. Now your computer, phone,
