Rubly virus removal guide
What is the Rubly screenlocker?
Rubly is a screenlocker malware. It operates by locking the screen (i.e. displays a full-screen window) and damages the Master Boot Record (MBR) - for the purpose of demanding payment. Rubly also claims to have encrypted the data stored on the infected system, which is the usual modus operandi of ransomware-type malicious programs. The discovery of Rubly is credited to malware analyst Karsten Hahn.
The text presented on the locked screen states that all of the victims' important files have been encrypted. To receive more information on how to get the decryption key, users are instructed to write to the email address provided. When the system is restarted/rebooted, the damaged MBR displays another message. It informs victims that their device has been infected by the Rubly trojan. Additionally, the note claims that all of the data has been encrypted. The users are told that they three attempts to type the correct decryption key. This message repeats that to receive the key, victims are to establish contact using the mail addresses provided. It is expressly advised against communicating with and/or meeting their ransom demands of cyber criminals. Since often, they do not uphold their end of the bargain, despite being paid. It is noteworthy, that the provided email addresses are from public email service provides (gmail, web.de). Furthermore, one of the mails is from a German provider, which possibly means that the criminals themselves are located/based in Germany. Such sloppy attempts at ensuring anonymity on their part may be due to the cyber criminals being amateurs. Whatever the case, Rubly screenlocker is deemed to be a high-risk malware and it must be removed without delay.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
"McAfee has Blocked your Windows", "Your Windows has been banned", "CRITICAL WARNING!" and "StalinLocker" are a couple different screenlockers. Malware of this type often incorporates various fake claims, for example - to trick users into believing that they are communicating with technical support or law enforcement. To elaborate, it may be claimed that the device's screen has been locked by the operating system itself or an anti-virus product (e.g. Windows or McAfee, like in the provided examples), due to some sort of serious threat/issue. This scam model is commonly used to push users into calling expensive fake tech support numbers and/or to request payment for "services rendered". Another model states that access to the device has been blocked by local law authorities, due to illegal material detected on the system. The ransom for unlocking in such scams is disguised as a fine for possession of illicit content. Regardless of what this malware claims and/or how it operates, the end-goal is the same - to generate revenue for the cyber criminals behind it.
How did ransomware install on my computer?
How to avoid installation of potentially unwanted applications?
It is advised against opening suspicious and/or irrelevant emails, especially any attachments or links present in such - as that can result in a high-risk infection. Only official and verified download channels should be used. It is also recommended to activate and update products with tools/functions, provided by genuine developers. Illegal activation ("cracking") tools and third party updaters should not be used, since they are often used to spread malware. To protect device integrity and user safety, it is crucial to have an anti-virus/anti-spyware suite installed and kept up-to-date. This software is to be used to run regular system scans and to remove detected/potential threats. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
