UPPER ransomware removal instructions
What is UPPER?
Discovered by dnwls0719, UPPER is the name of a ransomware-type malicious program. It operates by encrypting data and demanding payment for the decryption. As this ransomware encrypts, all affected files are appended with the ".UPPER" extension. For example, a file like "1.jpg" would appear as "1.jpg.UPPER" - following encryption. Once this process is complete, a ransom note - "infoUPPER.txt" is created on the desktop.
The ransom-demanding message in "infoUPPER.txt", informs victims that their files have been encrypted. It instructs users to establish contact with the cyber criminals behind the infection, via email. The victims' letters must contain the unique key, which is present in the ransom note. The message states that only the criminals responsible for the attack can restore the compromised data. The size of the ransom is not mentioned in this note. Before paying the unspecified sum, users can test decryption. Victims can attach up to two encrypted text or image files (no larger than 1Mb each) to their emails, and the criminals will send them back - decrypted. Yet, if users attempt to cheat and send a database, the ransom will double. Unfortunately, in most cases of such attacks, without the involvement of cyber criminals responsible - decryption is impossible. It may be, if the ransomware is still in development and/or has bugs/flaws. Whatever the case, it is expressly advised against meeting the ransom demands. Since often, despite paying - victims do not receive the promised decryption tools. Therefore, not only does their data remain worthless, but they also experience significant financial losses. To prevent UPPER from further encryptions, it must be removed from the operating system. However, removal will not restore already affected files. The sole viable solution is recovering them from a backup, if one was created prior to the infection and was stored in a different location.

Hack For Life, Npsk, ProLock and Velar are a few examples of other ransomware. Malware within this classification is designed to encrypt data of infected systems, in order to demand ransoms for the decryption tools/software. There are several crucial differences between these programs/infections: the cryptographic algorithms they use (symmetric or asymmetric) and the size of the demanded payment. The ransoms usually range between three and four digits (in USD). Cyber criminals typically request digital currencies (mainly, cryptocurrencies), due to transactions of them being difficult/impossible to trace. To ensure data safety, it is highly recommended to keep backups in remote servers and/or unplugged storage devices (ideally, in multiple different locations).

To eliminate malware infections our security researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Dubious and/or irrelevant emails should not be opened, especially any attachments (or links) present in them - as that can result in a malware infection. Only official and verified download sources should be used. It is also recommended to always activate and update software with tools/functions, provided by genuine developers. Illegal activation ("cracking") tools and third party updaters should not be used, as it is common for them to be used for malware proliferation. To protect device integrity and user safety, it is paramount to have a dependable anti-virus installed. Furthermore, it must be kept up-to-date, used to run regular system scans and to remove detected threats/issues. If your computer is already infected with UPPER, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Log in to the account infected with the UPPER 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.
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 UPPER 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 UPPER 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 UPPER 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 UPPER 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.
