WinRARER ransomware removal instructions

What is WinRARER?

WinRARER is a malicious software that is classified ransomware, it was discovered by GrujaRS. This ransomware puts files in an .ace archive file named "YourFilesHere-0penWithWinrar.ace", it puts it in "C:\YOUR-locked-FILES\" directory. This file is password-protected, in order to get a password victims are forced to pay cyber criminals who designed WinRARER a ransom. Also, WinRARER creates "RecoverYourFiles.htm", "RecoverYourFiles.rtf" and "RecoverYourFiles.bmp" files (ransom notes), it uses the last one to changes victim's desktop wallpaper.

As stated in all ransom notes, WinRARER locked files with WinRAR and it is impossible to use or access them without a password that can be purchased from cyber criminal who designed this ransomware. In order to make a payment and get a password victims have to use a link that can be opened only with a Tor browser. At the time of the research that website could not be accessed. However, it is not recommended to pay these cyber criminals or developers of any other ransomware. Quite often victims who pay them get scammed, they do not receive the promised decryption tools and/or keys. Unfortunately, most ransomware-type programs lock files with strong encryption algorithms and it is impossible to unlock/decrypt files without the tools that only developers of a particular ransomware have/can provide. Typically, the only way to recover files without having to contact and pay cyber criminals is to restore them from a backup. Also, it is recommended to uninstall ransomware as soon as possible so it could not cause any further encryptions. However, it is worth mentioning that uninstalling ransomware from the system does not make encrypted data accessible. In other words, files stay encrypted even after removal of malware.

More examples of malicious software that is categorized as ransomware are LockBit, JavaRatty and Hets. Typically, ransomware encrypts data/makes files inaccessible and creates a ransom note. The main differences between these programs are a price of a decryption and cryptographic algorithm (symmetric or asymmetric) that is used to lock (encrypt) data. One more thing that most ransomware-type programs have in common is that it is impossible to decrypt files encrypted by them without tools that only cyber criminals who designed them have. It is possible to restore files without their help only if ransomware is not finished (contains bugs, flaws) or victims backed up their data before ransomware attack. That is why it is always a good idea to have a backup of data created and keep it on a remote server and/or unplugged storage device.

How did ransomware infect my computer?

Typically, cyber criminals spread malicious programs like the WinRARER ransomware through spam campaigns, Trojans, fake software updaters, unreliable software download sources and unofficial software activation tools. If they do it by using spam campaigns, then they send emails that contain malicious attachments (or web links that, if clicked, download malicious files) to a lot of people and hope that someone will open attached or downloaded file. If opened, that file installs malware. In most cases they attach files such as Microsoft Office of PDF documents, archive files (like RAR, ZIP), executable files (.exe), JavaScript, and other files. Trojans are programs that can cause damage only after their installation. Once installed, a program of this type usually causes a chain infection: it installs other malware. Fake (unofficial) software updaters infect systems by installing malicious programs instead of updates or by exploiting bugs, flaws of outdated software that is installed on a computer. Examples of unreliable software download channels are Peer-to-Peer networks like eMule, torrent clients, free file hosting websites, freeware download pages, third party downloaders, unofficial websites, etc. Cyber criminals use these channels to spread malware by uploading malicious files disguised as legitimate. People who download and open files downloaded from sources of this kind risk to install malicious software by themselves. Software 'cracking' (activation) tools supposed to activate licensed (paid) software for free. However, those tools are often designed by cyber criminals who seek to infect computers with malware.

How to protect yourself from ransomware infections?

We recommend not to open attachments (or web links) that are included in irrelevant emails, especially if those emailss are received from unknown, suspicious addresses. All software and files should be downloaded from official websites, unofficial websites, various third party downloaders, installers and other tools that we mentioned above might be used to proliferate malicious programs. Furthermore, software (and operating system) should be updated though implemented functions and/or tools that are designed by official developers. Unofficial activation tools often install malware instead of activating installed programs, besides, it is not legal to use tools of this type. One more way to protect systems from being infected with malware is to regularly scan them with a reputable antivirus or anti-spyware suite and keep it always up to date. If your computer is already infected with WinRARER, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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