French101 ransomware removal instructions
What is French101?
French101 is a malicious software that is categorized as ransomware. Its developers use it to block victims from accessing their files by encrypting all their data. In order to regain access to their files, victims must to pay a ransom. French101 was discovered by security researcher Petrovic. Like most ransomware-type programs, it renames encrypted files by adding its own extension. In this case it changes name of the file to a random string and adds the ".french101" extension. For example, it renames file named "1.jpg" to "bvMqp5yz0AL98A.french101" and so on. French101 also creates a ransom note, the "HOW TO RECOVER ENCRYPTED FILES.TXT" text file.
French101's victims are encouraged to send cyber criminals their personal IDs as a confirmation that they are ready to pay a ransom. Besides, they are urged to do it as soon as possible, because the faster they will do it, the lower the price of a decryption (decryption tool/key) will be. In order to contact cyber criminals victims are provided with three emails: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org. Once contacted, they should send instructions on how to make a payment. It is mentioned in the ransom note that the payment must be done using Bitcoins. Before paying French101's victims can send its developers up to three files that they will decrypt free. Typically, cyber criminals offer free decryptions of some files as a proof that they have the tool that can decrypt encrypted files. Additionally, French101's developers urge their victims not to rename any of the encrypted files or/and not to try to decrypt them using other, third party software. According to them it might cause permanent data loss or increase the price of the decryption tool. Typically, people who develop these programs are the only ones who can provide tools required for a successful decryption. They use cryptography algorithms (symmetric or asymmetric) that are impossible to 'crack'. The problem is that most cyber criminals cannot be trusted. There are many cases where victims pay them money (send cryptocurrency) but do not get anything in return. Unfortunately, there is no free tool that could decrypt files encrypted by French101. The only option to recover files for free is to use data backup and restore all data from there.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Most ransomware-type viruses are very similar, they are designed to have two main purposes: to encrypt data and encourage victims to purchase a decryption key or tool. As a rule, main differences between these programs are the price of the decryption and cryptography algorithm that was used to encrypt data. Unfortunately, most victims are forced to contact cyber criminals because a decryption without using their tools is impossible. It could be possible only if ransomware is not fully developed, has bugs, flaws etc. These are the main reasons why we recommend to create data backups regularly and to store them on remote servers or unplugged storage devices. Other computer infections that are similar to French101 are MegaLocker, Langolier and Tellyouthepass.
How did ransomware infect my computer?
As a rule, to spread ransomware and other infections cyber criminals use spam campaigns, untrustworthy software download sources, software 'cracking' tools, Trojans and fake software updaters. They use email spam campaigns to cause infections through attachments. Cyber criminals attach malicious documents (such as Microsoft Office, archive, executable, PDF and other files) and hope that recipients will open them. Once opened, infected attachments download and install various viruses. Untrustworthy software download sources like free file hosting, freeware download websites, Peer-to-Peer (P2P) networks, unofficial pages and other sources of this kind can be used to present malicious (infected) files as legitimate. When people download and open them, they install viruses by themselves. Software 'cracking' tools often download and install ransomware and cause other computer infections instead of activating software, operating systems without having to pay for it. Another way to spread computer infections is via Trojans. If installed, these (malicious) programs spread other computer infections. In other words, they open 'backdoors' for other viruses. Fake software updaters can be used as instruments to download and install infections instead of updates, fixes, or to exploit outdated software's bugs, flaws.

How to protect yourself from ransomware infections?
Always analyze emails that contain attachments or web links. If attached file or link is presented in irrelevant email, received from unknown, suspicious address, do not open it. Download any software using official, trustworthy sources and direct links only. Third party downloaders and other sources that we mentioned above should not be used for that. Update software properly, using tools or implemented functions that are provided by official developers only. If software is not free, it should be activated properly, too. Usage of third party programs ('cracking' tools) is a cyber crime. Besides, these programs often cause computer infections. One more way to keep a computer safe from various infections is to have a reputable anti-virus or anti-spyware suite installed and to keep it enabled at all times. If your computer is already infected with French101, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the French101 ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining French101 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 French101 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.
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 protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as French101 ransomware.
Note that Windows 10 Fall Creators Update includes "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default this feature automatically protects files stored in Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
