Popcorn Time ransomware removal instructions

What is Popcorn Time?

Popcorn Time is a ransomware-type virus discovered by security researcher MalwareHunterTeam. Following infiltration, Popcorn Time encrypts various data stored on the infected computer. During encryption, this ransomware appends the names of encrypted files with the ".kok" or ".filock" extension. Following successful encryption, Popcorn Time opens a pop-up window and creates an HTML file ("restore_your_files.html"), placing it on the desktop. Both contain ransom-demand messages.

The messages inform victims of the encryption. The key is stored on a remote server owned by Popcorn Time's developers. Therefore, victims are encouraged to pay a ransom of 1 Bitcoin (approximately $750) to receive it. If the ransom is not paid within seven days, the key is permanently deleted and decryption becomes impossible. Popcorn Time has one feature making it unusual amongst ransomware-type viruses: it allows victims to decrypt their files free of charge using an affiliate link provided. Victims must promote this link to other users so that their computers are infected. If at least two of these other people pay the ransom, files are decrypted free of charge. The ransom demand message states that Popcorn Time's developers are students from Siria. They claim that the reason why they make these ransom demands is hunger in Syria. All payments are supposedly used to help refugees and impoverished people of this nation. Be aware, however, that these claims are false - Popcorn Time's developers are cyber criminals who simply aim to generate revenue. In addition, research reveals that cyber criminals often ignore victims, despite submitted payments. Therefore, these people should never be trusted - never attempt to contact them or pay any ransom. There is a high probability that you will be scammed. There are currently no tools capable of restoring files encrypted by Popcorn Time. The problem can only be resolved by restoring your files/system from a backup.

There are dozens of ransomware-type viruses similar to Popcorn Time including Sage, GoldenEye, and *.osiris - these are just some examples from many. As with Popcorn Time, other ransomware-type viruses also encrypt files and make ransom demands. The encryption algorithm (symmetric/asymmetric) and cost of decryption are the only major differences. These viruses are often distributed using third party software download sources (peer-to-peer networks, freeware download websites, free file hosting websites, etc.), malicious files attached to spam emails, fake software update tools, and trojans. Therefore, you should never download software from unofficial sources or open files received from suspicious emails. In addition, keep your installed applications up-to-date - cyber criminals are capable of exploiting software bugs/flaws to infect the system. Never use a third party update tool - it might be fake and can result in high-risk computer infections. Always use a legitimate anti-virus/anti-spyware suite. The key to computer safety is caution.

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Popcorn Time ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Popcorn Time are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Popcorn Time, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
