Since the free antivirus subscription on my notebook PC expired more than 3 years ago, I have never subscribed to any antivirus software to protect my lovely notebook any more. You may ask why I leave my computer stay unprotected, I have some explanations for you.

I worked as a network engineer in the past, and I’m actually a security minded computer user. Based on what I have learned, computer security is all about staying up to date. Computer is loaded with a variety of software and millions of code, and new bugs are found daily. That’s why the vendors keep updating their software which includes security patches. And what users need to do is simply updating their software as soon as the security update available before the bad guy exploiting the bugs. That’s my first trick, stay up to date!

Do I have the second trick? Of course, here it is: Do not download and install any software from untrusted sources. This trick is simple but hard to do, why? Because bad codes are always embedded in software you need, it’s often hiding in the free software you try to download. Believe me! It’s easy to say but hard to obey.

And what is the last trick? Do not let a strange USB flash drive plugged into your computer. So many viruses spread through this method. It means your computer must be fully isolated. Stay away from exchanging portable drive with friends. This is the hardest thing! And I don’t think you can live that way, but I do that as I’m not a student neither a corporate worker who always interacts with friends and colleagues.

Do I really live without antivirus guard? Yes, but I don’t want you to follow me. It’s hard to live like this in the world “wild” web age. As I told you before, the most challenging thing is the free software that’s available out there and always ready to cheat you. If you want to live with more confidence, get an antivirus and stay protected, and your life will be better.

After 3 years, now I want to live normally with confident, I’m so tired to stay unprotected that forces me to stay focus and isolated. I just installed an antivirus and internet security tool on my brand new desktop PC, and I will get it too for my old notebook as soon as I finish upgrading the hardware and operating system.
