How to protect your computer from Ransomware?

After the WannaCry Ransomware affected 105 countries, this piece of information is essential.

Ransom is a price demanded for the release of a captive. The term ransomware has evolved from this. Ransomware is a malicious software that blocks your access to data until a certain amount of ransom is paid. It displays a message that demands payment to unlock it. Ransomware attacks are carried out by a trojan, which is a program that makes the data vulnerable or deletes the data.

Ransomware is a denial-of-access attack i.e. it blocks the user from using the computer’s data. In technical terms, it encrypts the data and denies its decryption until a fixed amount is paid. It is also known as cryptoviral extortion.

There are two types of ransomware:-

          1.Lockscreen ransomware: It displays a full-screen message demanding money, and prevents you from accessing your PC or files.

           2.Encryption ransomware: This malicious software resides in your PC and changes your files. It does this by encrypting the files into some other format that needs deciphering and decrypting of a different standard.

 

Several ways to counter ransomware are:-

Back up data

When a ransomware attacks, it block access to data or deletes files, but if you have a backup of your data, you can restore it into your system. Thus, when it attacks you can reset your system and have a backup of it. The key is having a regular backup of data to some external device or cloud, which is not connected to your drives.

Use a crypto locker prevention kit
