What Is Ransomware?
‘Ransom’ is a word that itself gives you the understanding of a crime associated to kidnapping. But, yes, it is a bit tricky to understand how this word can be linked to the world of computers. Ransom is a predefined amount of money which is used to retrieve the private data of your computer when your PC gets hit by a ransomware attack. This malware denies your access to your own private data and the only way to retrieve your access is to get the decryption key by paying the ransom amount.
How To Hold Onto Your Private Data From Ransomware Attack?
WannaCry has infected the older versions of Windows. So, before we jump to any of the protection steps, you must update your current operating system. And now, counting the other pieces of advice that can save your private data from getting affected by this malicious attack.

It is important that you have an updated recovery system in place if your PC faces ransomware attack. Always remember to maintain two backup copies; one is on the trusted cloud network (try to maintain an auto recovery system) and another one is on any physical storage like portable hard drives or thumb drives. Also, never leave your extra physical storage of data to stay connected to the PC as the malware might affect the failure of your hard drive too.
2. Always Use A Powerful Antivirus Software
This is another way to protect your data from getting affected by ransomware. Also, never switch off ‘heuristic functions’ as it is capable of detecting ransomware attacks.
3. Do Not Trust Random Mailers
It is advisable not to compromise your data by clicking on malicious links which are distributed by seemed to-be promising fake email messages or any kind of medium.
