Remove Foop Ransomware (Decrypt .foop Files)

By CK Quinito | Posted on March 9, 2020 | Updated on May 13, 2020

Foop ransomware is a data-locker virus that uses complex method to encrypt valuable files of its victims and remains inaccessible until a ransom fee is paid. Using a unique algorithm, the only way to recover the files is through a decryption tool provided by Foop developers. Even file restoration programs offered by a number of developers are meaningless in this type of attack.

Primary objective of Foop ransom virus is to encrypt important files such as photos, personal documents, databases, archives, and so on. Once Foop starts to operate on computer, it will spy throughout the system locating files that are vital to users. Consequently, this ransom virus will add .foop extension by renaming the current file names of infected data. Then, Foop ransomware will drop a text file _readme.txt note file, which stands as a ransom message stating the instructions and demands of hackers.

The usual ransom ranging from $490 to $980. Foop developers prefer to use crypto-currency when receiving payments. Victims should comply with the demands of hackers to regain access to the corrupted files. As Foop ransomware developers promised, once the ransom fee is settled, hackers will deliver the decryption tool to use it for restoring the infected files. However, paying the hackers will not assure that victims will bring back their files; there are instances that after settling the fee, hackers did not respond at all. Computer security experts advised that, instead of wasting time negotiating with the cyber criminals, give more time, and focus on removing the ransomware in the system.

Developers of viruses always find a way to distribute their malicious software. Like for Foop ransomware, it is spreading on computers probably because of spam email messages or intrusive advertisements online. Hackers tend to send emails to their prospects. They will attach malware-infected files along with it, which is mostly a ransomware. Clicking and opening the attachments would activate it in the operating system. In addition, there are advertisements designed to associate a malware. Once the ads were clicked, it will start to install unwanted software on the computer and starts to invade the operating system.
