​WannaCry or Wanna Decrytor ransomware is an informatic virus that attacks Windows operating system based computers primarily (including servers) by taking advantage of system vulnerabilities exploited by Eternalblue, a tool believed to be developed by the USA National Security Agency. What is the unique effect once infected by the virus? Well, you will notice it fast. The system will show you a Popup window letting you know that your computer is infected, all your files are encrypted, and for you to recover it all, they require a ransom payment using bitcoins. Unless you make the payment, all your files will stay encrypted. The worst thing about this virus is that, if you do not pay in a certain period, the ransom payment will keep rising.
But, wait! The intention of this article is not to create panic. Even though you should panic if your computer got infected and you didn't backed up your files recently (last day or night before the infection). 

Updating your smart device operation system (OS) seems to be a very straight-forward process and, in most cases, it is. With a few clicks, you can install the latest OS update to your smartphone, tablet or smart watch. But sometimes, the unexpected happens when or after the update is completed. Your device doesn’t normally start anymore, stands still in loading mode, or does not work properly, and your only way to fix it appears to be wiping out your entire device system or restoring it to manufacturer defaults if you are lucky. You do so, it means you will lose almost everything. And everything means, your photos, files, text messages, Whatsup conversations, videos, audios, and so on if you don’t previously back up your smart device.
