ATAWARE ransomware removal instructions

What is ATAWARE?

ATAWARE was discovered by Securityinbits. It is a high-risk virus, a ransomware-type program that is designed to encrypt files stored on victim's computer and keep them unusable unless a ransom is paid. It adds the ".ATANUR" extension to every encrypted file, for example, if a file is named "1.jpg", then ATAWARE will rename it to "1.jpg.ATANUR" and so on. Once a computer is infected and files are encrypted, ATAWARE displays a ransom note in a pop-up window. It also creates the "Decryptor.exe" file and puts it on desktop.

Displayed pop-up window says that all victim's data was encrypted and it cannot be accessed anymore. Cyber criminals behind this ransomware present themselves as just random people who use ATAWARE to encrypt files stored on other people's computers. According to them, the price of decryption is 500 points (of something). However, they do not provide any details on how to contact them or to pay them. For this reason it is very likely that this ransomware is still in a development state. Clicking the "Decrypt" button in a pop-up window opens another pop-up window saying to wait until the decryptor finishes its job. However, it seems to be not working. Same with the "Decryptor.exe" file placed on a desktop - it does not work. Ransomware-type programs that are unfinished sometimes are possible to 'crack' without having to contact cyber criminals or pay them a ransom. However, there is no tool that could be capable of decrypting files encrypted by ATAWARE, at least not at this moment. Most of the times cyber criminals are the only ones who have the right decryption tools. In this case we recommend to use data backup and to restore all files from there.

As a rule, ransomware-type programs operate very similarly. They encrypt data and display ransom notes. Here are some other examples: MegaLocker, Langolier and Etols. Main differences between these programs usually are price of a decryption and cryptography algorithm (symmetric or asymmetric) used for encryption. Unluckily, most encryptions are impossible to decrypt without using particular decryption tools. Typically, they can be provided only by cyber criminals. Free decryptions usually are possible only if ransomware is not finished, has bugs, flaws and so on, but that does not happen often. For these reasons we recommend to create data backups regularly and keep them stored on remote server or unplugged/disconnected storage device.

How did ransomware infect my computer?

Most common ways to proliferate ransomware (and other viruses) are: though spam campaigns (emails), fake software updaters, untrustworthy software download sources, Trojans and software 'cracking' tools. Very often cyber criminals attempt to infect people's computers through malicious email attachments. They send emails that contain Microsoft Office documents, PDFs, executables (.exe files), JavaScript files, archives (ZIP, RAR and others) and so on. If opened, they download and install ransomware or other malicious program. Fake software updaters cause damage by exploiting outdated software's flaws, bugs or by downloading and installing viruses instead of updates or fixes. P2P (Peer-to-Peer) networks like eMule, torrent clients and so on, third party downloaders, unofficial pages, freeware and free file hosting websites and other sources of this kind are often used to present infected files as legitimate. If users download and open them, they install malware by themselves. Most Trojans are designed to cause chain infections, they spread other malicious programs. However, to cause any damage a Trojan must be already installed. Software cracking tools are programs supposed to activate paid software for free. However, some cyber criminals use them to spread computer infections as well. It means that these tools often install malicious programs instead of activating software or operating system.

Additional Information At the time of research ATAWARE wasn't fully developed, since it did not provide any payment information and its decrypt function wasn't working.
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.

How to protect yourself from ransomware infections?

We advise not to open attachments that are presented in emails received from unknown, suspicious addresses. Files that are attached to irrelevant emails (even if they are presented as important, official) should not be opened. Update installed software (or operating system) using implemented functions or tools provided by official developers only. Any other (third party) tools cannot be trusted for that. Moreover, download all software from official websites and using direct links, not some other, questionable sources. Usage of software cracking tools is illegal and often leads to serious computer infections. Having a reputable anti-spyware or anti-virus software installed and keeping it enabled is really important too. If your computer is already infected with ATAWARE, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Step 2

Log in to the account infected with the ATAWARE virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a 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.

Boot your computer in Safe Mode with Command Prompt

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

system restore using command prompt type cd restore

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

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 ATAWARE 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 ATAWARE 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 ATAWARE 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 ATAWARE, 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 ATAWARE 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.

Controll Folder Access

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.
