Foop is a virus program that is programmed to coerce you into sending a ransom to its creators by keeping you from accessing your files. Foop falls under the Ransomware virus category and it uses a data-encryption algorithm to lock users’ files.


The Foop virus will encrypt your files and leave a message in a _readme.txt file

Throughout the past five or so years, the Ransomware malware category has undergone a massive boom both in the sheer number of viruses of this type that are created and in terms of how advanced those viruses are. The model of how a Ransomware threat operates is rather simple – the virus enters the user’s machine without getting notice (typically helped by a Trojan horse backdoor) and then it launches a process that encrypts most or all of the user’s personal files. Once a given file gets encrypted, no conventional program can open it and so, after the Ransomware encryption completes, the victim becomes utterly incapable of opening, using, or modifying any of his or her files. This gives the hackers behind the virus the perfect opportunity to blackmail their victims for a ransom. If the victim pays the sum, the cybercriminals would immediately send back a unique decryption key that can only unlock the files on that specific computer. Of course, not all users would be willing to pay the ransom – some may not be able to afford to make the payment and some may simply not care all that much about the lost data to pay for its recovery. Nevertheless, many people do indeed pay the ransom which, however, is not a very advisable thing to do.

The Foop virus

The Foop virus is a piece of malware that uses stealth to infiltrate Windows PCs and then lock up the files located on their hard disks. The Foop virus doesn’t show any red flags during the process of locking the files so detecting it is very difficult.

Most people only come to realize what has happened in their computer once the malware has already done its job of encrypting their files and is ready to make its ransom demands known to the victim. Normally, those demands are presented in the form of a pop-up on the screen or a notepad file, in which the sum for the ransom and the instructions on how to pay it are provided.

As we said, even if you highly value the files that the virus has encrypted, paying the money shouldn’t be your first action. Cybercriminals who use Ransomware to blackmail their victims oftentimes don’t keep their promises and simply take the money without providing the users with working decryption keys.

The Foop file decryption

The Foop file decryption is the process that would allow victims of this virus to regain the ability to access their files. The Foop file decryption typically requires a special key to successfully complete but there may be some other options one can try.

Several alternative recovery suggestions that can be tried for free will be shown to you in the second part of the following removal guide. However, before you get to them, we highly recommend that you eliminate the virus by completing the removal steps you will see next:


Name Foop
Type Ransomware
Danger Level High (Ransomware is by far the worst threat you can encounter)
Symptoms Ransomware typically doesn’t show signs of its presence in the system while it is still busy encrypting the user’s files. It only reveals itself through the ransom note once the targeted files have been locked.
Distribution Method Pirated programs and disguised Trojan horse viruses are usually the tools used to spread Ransomware.

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).



We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
