One of the ways that you can tell if your computer or any device or not is to check and see if it had any security software that can keep hackers and viruses at bay. No matter how old you get and it does not matter how many devices you have, always make sure that they have a security system that can help them fight off viruses and malware so that way the firewall can be breached by hackers by any means necessary because hackers are evolving and growing by the day so that means that technology is very , vulnerable to almost anything and a lot can happen in just a blink of an eye. Before you know it, all of your data can be gone and exposed to the web in a matter of seconds and all of your personal information is leaked as well thanks to a small data breach that was not meant to be harmful. That is why it is never bad idea toc check and see if your mobile device has security because you do  not know what can happen with the amount that comes out and the amount of technology that comes out every day and the way technology improves every year.
