How to Secure Yourself against CryptoLocker

Ransomware has been increasing rapidly over the past few years, being one of the major threats for Internet users universally. With the term of Ransomware, we refer to any malicious software that is installed without your consent and takes your data as hostage. Of course, this happens after the Ransomware finds an open hole and penetrates your system. In this way, your data gets encrypted and only then do you notice that something is wrong.

If you wish to get your data back without any loss or damage, you will be expected to pay the money that the hackers who have planted the Ransomware demand. This can be truly frustrating and especially in the case of top secret and classified documents, professional files and data that is not stored anywhere else. Even if you detect the ramsonware after the completion of the encryption, you do not get to succeed in doing much. You can uninstall it and even damage the source of the Ransomware, but the decryption key will not get inside your hands without the proper monetary fee.

One such fine example of Ransomware has been CryptoLocker. This threat has been sent in the form of an email attachment and the people primarily targeted were residents of the US and the UK. The spam mails have affected large groups of people and consequently a lot of people have been forced to pay the necessary penalty for being given the decryption key to their digital property.
