How to protect yourself from WannaCry Ransomware?

WannaCry is a ransomware that is spreading fast and affecting many computer systems world wide including government systems, hospital systems etc.

It uses a vulnerability in Microsoft Window's SMB protocol ( SMB stands for Server Message Block) which turned on by default. Once infected it asks the victim to pay 300$ bitcoins in order to remove the infection and decrypt all the encrypted files.

Once infected, WannaCry also scans for other vulnerable computers connected to the same network, as well scans random hosts on the wider Internet, to spread quickly.
