How to remove FessLeak Ransomware?

FessLeak is classified as a ransomware infection and as such what it does is to encrypt all the files on your PC. This means that you will not be able to open your photos, videos, or text documents if  FessLeak has gained access to your system. Shortly after infiltration, FessLeak will present you with a message informing you about the encryption of your files and asking you to pay a ransom in order to get them back. No matter how worried you are and how important the encrypted files are, you should not spend the requested amount money because we can assure you that it will be useless. Instead, you should do your best to get rid on the malicious ransomware infection and start using your PC as you usually do.

How did I get infected with?

Same as other infections, ransomware is distributed in several ways. The most common one is by attaching the infection to a spam email and disguising the email as a real and urgent message. Then, when the user opens it and downloads the attached file, he or she automatically installs the malicious infection. Researches show, however, that FessLeak mainly takes advantage of the vulnerabilities of the Adobe Flash player. If this program is not kept up-to-date, it creates opportunities for cyber criminals to exploit it and make you a subject to infections by FessLeak. Also, if there is no active legitimate security tool to protect your system, it is very likely that you will soon end up with a bunch of infections on your PC, and pray that they are not ransomware like FessLeak.

Why is FessLeak dangerous?

There is a group of ransomware infections called Crypto, and FessLeak is the newest member of this group. Unfortunately unlike its predecessors FessLeak will fully encrypt your files, so it will be practically impossible to decrypt them. Hence, you should not fall for the lies in the warning message that assures you that purchasing a special key or a code will restore your files. The only thing that can help you in this situation is file back-up, if you have done any prior to infecting your system with FessLeak. Another problem that may occur concerns your privacy. FessLeak will collect information about you that can be used for all kinds of purposes by the cyber criminals who created this ransomware. The moment you see a message by FessLeak on your desktop, do not panic but immediately remove the infection from the PC.
