File Spider ransomware removal instructions
What is File Spider?
File Spider is a ransomware-type virus discovered by malware security researcher, Lawrence Abrams. It is distributed using spam emails with malicious attachments (MS Office documents) that execute a macro command to download and run malware. Developers target users mainly from Serbia, Bosnia and Herzegovina, and Croatia. Immediately after infiltration, File Spider encrypts most stored files and appends filenames with the ".spider" extension (e.g., "sample.jpg" becomes "sample.jpg.spider"). From this point, files become unusable. Once files are encrypted, File Spider runs the "dec.exe" file (downloaded by the attachment and placed in the "%AppData%\Spider" folder). In addition, it creates two shortcuts: "HOW TO DECRYPT FILES.url" (placed in each existing folder and leading to a "how to decrypt" online video tutorial) and "DECRYPTER.url" (placed on the desktop, and which opens the "dec.exe" file).
The pop-up window contains a message that informs victims of the encryption and instructs them what to do next. To restore files, users must first visit File Spider's website and pay a ransom. The message states that decryption requires a unique key. Unfortunately, this information is accurate. File Spider employs AES-128 cryptography and, thus, it is impossible to restore files without a key generated uniquely for each victim. In addition, the primary key is encrypted using the RSA algorithm (which generates a second key), thus making things even more complicated. Cyber criminals store these keys on a remote server and users are encouraged to pay 0.00725 Bitcoin (currently equivalent to ~$120) in exchange for them. The message also states that victims have four days (exactly 96 hours) to submit payment. After this period, the keys are permanently blocked/deleted and restoring files becomes impossible. Despite these threats and demands, cyber criminals cannot be trusted. Research shows that these people commonly ignore victims, once ransoms are paid. If you pay, there is a high probability that you will be scammed and receive no positive result. As well as losing your money, you will also support cyber criminals' malicious businesses. Therefore, we strongly advise you to ignore all requests to pay. Unfortunately, there are no tools capable of restoring files encrypted by this ransomware and the only solution is to restore your files/system from a backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
File Spider is virtually identical to dozens of other ransomware-type viruses such as Wallet, ExecutionerPlus, Halloware, and many others. As with File Spider, these malware infections also encrypt stored files and make ransom demands. In most cases, these viruses have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Research shows that, unfortunately, they employ algorithms that generate unique decryption keys. Therefore, unless the malware has certain bugs/flaws (e.g., stores the key locally, is hard-coded, etc.), restoring files manually without involvement of developers (contacting these people is not recommended) is impossible. File Spider and other ransomware-type viruses present a strong case for maintaining regular data backups. Remember that backup files must be stored on a remote server or external storage, otherwise the virus encrypts them as well.

How to protect yourself from ransomware infections?
To prevent this situation, be very cautious when browsing the Internet. Never open files received from dubious email addresses. In fact, these emails should be deleted without reading. Furthermore, download your software from official sources only and, if possible, using a direct download link. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, we strongly advise you to avoid using any third party updaters - use implemented "Update" functions or at least tools provided by the official developer.
File Spider ransomware ransom-demand message:
YOUR PC HAS BEEN INFECTED WITH FILE SPIDER VIRUS
As you may have already noticed, all your important files are encrypted and you no longer have access to them. A unique key has been generated specifically for this PC

To visit our website your need to install a special browser named Tor Browser. Be aware, our website is reachable only via Tor Browser and if you try to visit it using any other browser eg. Chrome, it won't work! Tor Browser can be downloaded from its official website listed below. Use newly installed browser to visit our website address. On our website there is a online tool that can generate decryption key using your ID code, use that tool and you will get the key needed to decrypt your files. Also, you will be asked to make a payment for your Decryption Key, you will need a Bitcoins for that. More about bitcoins read in Help section. After your get your key, select Decrypter from menu and follow the instructions provided on that page. This all may seem complicated to you, actually it's really easy. A link to Video Tutorial with live demonstration can be found inside Help Section. Good Luck!

Enter your Decryption Key and click Start Decrypting, seat back and relax, in few minutes you will have full access to all your files!
Text presented within this tab:
During encryption process a unique key has been generated, used to encrypt your files, and then destroyed. To decrypt your files you need that key. We call that key a Decryption Key. You can not use the key from other PC, it won't work, you need a key corresponding to your PC. Your Decryption Key, required for decryption process, can be generated only from something that we call a ID Code, you will find that code below.

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 File Spider 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 File Spider 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 File Spider 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 File Spider 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 the 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 is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
