How to Protect Your System from Ransomware
With WannaCry, ransomware is back in action again. The threat has been spread around the world infecting thousands of systems making them crawl. Ransomware typically is a real-time threat which works based on Cryptovirology spreading cryptoviral extortion attacks that block users to access to data until a ransom is paid. Whenever it attacks your system it displays a ransom message on your system asking for the ransom to be paid to get access to data again. It has been in existence for decades but the threat is now bigger and more dangerous.
Types of Ransomware
