Rodentia ransomware removal instructions
What is Rodentia?
Rodentia is a ransomware-type infection that belongs to Jigsaw ransomware family. The purpose of this malware is to stealthily infiltrate computers, encrypt data and to make ransom demands. Such behavior is very common for ransomware-type infections. However, due to the fact that Rodentia is poorly programmed, it doesn't actually encrypt files. All it does is displays a pop-up window that contains a ransom-demanding message. This ransomware was firstly discovered by MalwareHunterTeam.
The message states that files are encrypted and that victims have to pay a ransom in order to restore them. It is also noted that a certain amount of files are being deleted every hour. Now, as mentioned above, Rodentia has a number of flaws which leads to its inability to encrypt data. However, it is currently unconfirmed whether it actually deletes data - this function might work. Additionally, there's a huge credibility that crooks will eventually release an updated Rodentia's version which will actually encrypt data. Now the price for "recovery" is $20, which is a joke comparing to other ransomware infections that demand for thousands of dollars. Nevertheless, no matter how low or high the price is, it should never be paid, even if your data is actually compromised. Ransomware developers in general are notorious for ignoring victims after they submit payments. Users simply support cyber criminals' malicious businesses and get nothing in return. For this reason, we highly recommend to ignore all encouragements to contact these persons and especially submit payments. Again, at the time of research this malware wasn't able to encrypt data. However, it might actually start deleting files. For this reason, you should immediately scan the system with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Internet is full of high-risk ransomware infections that actually encrypt data and make ransom demands. YOUR_LAST_CHANCE, CROWN, Dqb - these are only few examples from a long list. Although the developers are different, almost all of these viruses are virtually identical. There typically are only two major differences: size of ransom and type of encryption algorithm used. Unluckily, encryptions are often performed using AES, RSA, and other similar cryptographies that generate unique decryption keys. Therefore, if the virus is developed flawlessly, manual decryption without developers' interference is impossible. In order to prevent such data losses we highly recommend to maintain regular data backups. Just keep in mind that locally stored backups will be compromised together with regular data, which is why you should store them in some remote server or unplugged storage device. We also recommend to have multiple backup copies stored in different locations, because there's always a chance that used server/hardware will be damaged.
How did ransomware infect my computer?
Infections like Rodentia are usually distributed using trojams, fake software cracks and updaters, email spam campaigns, and third party software download sources. Trojans are malicious applications designed to cause so-called "chain infections". Such apps simply infiltrate computers and inject them with additional malware. Fake software cracks inject malware rather than activating paid software for free. Same goes for fake updaters which infect systems by exploiting outdated software's bugs/flaws or simply downloading and installing malware rather than actual updates. Crooks employ spam campaigns to send hundreds of thousands of emails consisting of deceptive messages and malicious attachments. These messages usually present attachments as some important documents - this way recipients get tricked into opening malicious links/files. Last but not least are unofficial software download sources, such as Peer-to-Peer (P2P) networks, free file hosting/freeware download websites, and similar. As with email spam campaigns, such sources are used to spread malware by presenting it as legitimate software. Users end up downloading and installing malware manually.

|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate Rodentia virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
In order to prevent this situation users must be very cautious when downloading/installing/updating software, as well as browsing the Internet. Always be sure to carefully analyze every single email attachment received. Files/links received from suspicious/unrecognizable emails should never be opened. Desired programs should be downloaded only from official sources, preferably using direct download links. Third party downloaders/installers usually include rogue applications, which is why such tools should never be used. Proper software maintenance is also extremely important. Keeping installed applications and operating system up-to-date is extremely important. Yet this should be achieved only through implemented functions or tools provided by the official developer. It is important to know that software piracy is a cyber crime. Moreover, most of cracking tools are fake, meaning that the risk to infect system is extremely high. Hence, you should never attempt to activate installed software using any third party/illegal tools. On top of all that, be sure to always have a reputable anti-virus/anti-spyware suite installed and running - tools of this type will eliminate most of infections before they'll harm the system. The key to computer safety is caution. If your computer is already infected with Rodentia, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
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 Rodentia 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 Rodentia 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 Rodentia 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 Rodentia 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.
Windows 10 users should install this update to protect their data from ransomware attacks. Here's more information on how to get this update and add additional protection layer from ransomware infections.
