Forv ransomware removal instructions

What is Forv?

Discovered by GrujaRS, Forv is a piece of malicious software, belonging to the Paradise ransomware family. This malignant program is designed to encrypt data and demand a ransom for its decryption. As Forv encrypts, all files are appended with the "_forv_{victim's ID}.for" extension (the identification code is individually generated and consists of a random string of characters). Therefore, a file like "1.jpg" would appear as something similar to "1.jpg_forv_{6LHH0Q}.for", and so on. Once this process is competed, a text file titled "---==%$$$OPEN_ME_UP$$$==---.txt" is dropped onto the desktop.

The message in the text file informs affected users that their data has been encrypted. To decrypt it, users are to contact the developers of Forv via an online chat. The web-link of the chat is provided in the note. To log into it, victims are told to use their email address and ID number (written both in "---==%$$$OPEN_ME_UP$$$==---.txt" and in the filename of every compromised file). The cyber criminals guarantee an immediate response. The message ends with warnings against actions, which will lead to permanent data loss. Users are told not to rename the encrypted files and not to attempt decrypting them with third party software. Additionally, criminals claim that running an anti-virus or removing the ransomware program will also result in data loss. The decoders (decryption keys) of other victims will be ineffective, as each key is unique. Unfortunately, ransomware uses strong encryptions, which usually cannot be broken. Typically, only the software used to encrypt data - can decrypt it. Regardless, it is strongly advised against meeting any ransom demands and/or communicating with cyber criminals. These individuals are not to be trusted and often, despite paying - victims do not receive the promised decryption tools/software. Therefore, their files remain encrypted and essentially worthless. Removing this malware will not restore the data, however it will prevent Forv from further encryptions. The only possible solution is recovering the files from a backup, if one was made before the infection and stored separately.

HakbitAsusDecrypmeDavesSmith are just a few examples of malware similar to Forv. All ransomware-type programs encrypt data and demand payment for decryption tools/software. However, the cryptographic algorithm they use (symmetric or asymmetric) and the ransom sizes - differ from one infection to another. The ransoms range between three-digit and four-digit sums (in USD). Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are preferred by cyber criminals, due to transactions of such being difficult/impossible to trace. As mentioned, most malicious software under this classification cannot be "cracked". It may be possible, if a ransomware is still in development and/or has certain flaws/bugs. To protect data against infections of this kind, it is recommended to keep backups in remote servers and/or unplugged storage devices. Ideally, several backup copies should be stored in different locations.

How did ransomware infect my computer?

Usually, ransomware and other malicious software is spread through trojans, spam campaigns, untrustworthy download channels, fake software updaters and "cracking" (activation) tools. Trojans are a type of malware, designed to cause chain infections (i.e. download/install malicious content). Massive scale campaigns are used to send out deceptive emails with infectious attachments (or web-links leading to them). The emails are often disguised as "important", "official" and other similarly urgent mail. The attached files come in various formats (e.g. archive and executable files, PDF and Microsoft Office documents, JavaScripts, etc.), opening them causes the system infection. P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites, third party downloaders and similar sources are considered to be untrustworthy, therefore likely to offer dubious and malicious content. Fake updaters exploit flaws of outdated programs and/or simply install malware, instead of the promised updates. Illegal activation ("cracking") tools infect systems similarly, by downloading/installing malicious software, rather than activating licensed product.

How to protect yourself from ransomware infections?

It is recommended not to open suspicious and/or irrelevant emails, regardless of any priority labels. Attachments found in suspect mail must never be opened, as doing so can trigger them to begin downloading/installing malware. Content should be researched and downloaded only from official and verified channels. Software activation and updating is to be done via tools/functions provided by the legitimate developers; "cracking" tools and third party downloaders are deemed to be a safety threat. Users are strongly encouraged to have a dependable anti-virus/anti-spyware suite installed and kept maintained with newest updates. These programs are to be used for regular system scans and elimination of potential threats. If your computer is already infected with Forv, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

4. In the opened window, click "Next".

restore system files and settings

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 Forv ransomware virus infiltrating your PC).

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 Forv 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 Forv 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 Forv, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 Forv ransomware.

Note that Windows 10 Fall Creators Update includes a "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, and Desktop folders.

Controll Folder Access

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:
