Asus ransomware removal instructions
What is Asus?
Belonging to the CrySiS/Dharma malware family, Asus is a ransomware. It was discovered by Jakub Kroustek. This malicious program is designed to encrypt data and demand a ransom (i.e. payment for the decryption tools/software). During the encryption process all files are retitled a unique ID number (generated for each victim), developers' email address and the ".asus" extension. To elaborate, "1.jpg" would appear as something like "1.jpg.id-1E857D00.[DataBack@qbmail.biz].asus". After this process is complete, Asus drops a text file - "FILES ENCRYPTED.txt" on the desktop and displays a pop-up window.
The text file informs victims that their data has been locked and to recover it, they should write to the email addresses provided. The pop-up window contains a more detailed ransom note. It states that the data has been encrypted and to decrypt it, users must contact the cyber criminals behind Asus. The email must contain affected user's unique ID number in the title/subject of the letter. Should the developers of this malicious software not reply in 24 hours, victims are to use the alternative email address. The size of the ransom will depend on how quickly the criminals are contacted, the desired currency is Bitcoin cryptocurrency. Once the transaction is complete, the decryption tool will be sent. As proof, one file can be decrypted free of charge; provided, if it is no larger than 1Mb (non-archived) and contains no valuable information (e.g. database, backups, large excel sheet and similar). Furthermore, there are instructions given on how to obtain Bitcoins. Users are also warned not to rename the encrypted files and/or attempt manual decryption with third party software - else, they risk permanent data loss. Unfortunately, most ransomware-type programs use strong encryptions, which typically can only be decrypted by the software, initially used for the encryption. Despite this, it is expressly advised against meeting the ransom demands and/or communicating with cyber criminals. Often, even though victims pay - they do not receive the promised tools; leaving their files permanently damaged. Removing Asus will not restore the compromised data, however removal will prevent it from further encryptions. The only possible solution is recovering the files from a backup, if one was made prior to the infection and stored separately.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Worm, CCryptor, PBD are a few examples of malware similar to Asus. All ransomware encrypts data and demands a ransom to be paid. However, the cryptographic algorithm they use (symmetric or asymmetric) and the size of the payment - differs from one infection to another. Usually, these sums range between three-digits and four-digits (in USD). Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are preferred by cyber criminals, as transactions of such are difficult/impossible to trace. Unless a ransomware is still in development and/or has certain flaws/bugs, manual decryption (without the interference of criminals, who encrypted it) - is impossible. To ensure data safety, backup copies should be kept in remote servers and/or unplugged storage devices. Ideally, multiple backups should be stored in different locations.

|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 Asus virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Suspicious/Irrelevant emails should not be opened, especially ones received from unknown addresses. Any attachments (or web-links) found in such mail must never be opened - as that is the source of a potential system infection. It is recommended to only use official and verified download channels. Software activation and updating should always be done via tools/function provided by genuine developers; using illegal activation ("cracking") tools and third party updaters - is ill-advised. Users are strongly urged to have a dependable anti-virus/anti-spyware suite installed and kept updated. This software is to be used for regular system scans and removal of detected threats. If your computer is already infected with Asus, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.
Free decryption as guarantee
Before paying you can send us up to 1 file for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click 'Buy bitcoins', and select the seller by payment method and price.
Also you can find other places to buy Bitcoins and beginners guide here:
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

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 Asus 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 Asus 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 Asus 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 Asus 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.
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.
