Polleryou ransomware removal instructions

What is Polleryou?

Polleryou (also known as Rentyr) was discovered by S!Ri. This ransomware encrypts victim's files, however, unlike most programs of this type it does not append any extension to their filenames. Polleryou changes victim's desktop wallpaper and creates a ransom note, a text file named "Read-me22.txt". This file contains instructions on how to contact Polleryou's developers and pay them a ransom (purchase a decryption tool from them).

As stated in the ransom note (which is written in both English and Russian languages), Polleryou encrypts all files (photos, videos, audios, documents, etc.) and it is impossible to decrypt them without a particular decryption tool that can be purchased from its developers for $100. Victims have to pay a ransom in Bitcoins by transferring it to a provided BTC wallet and then contact cyber criminals via polleryou1@ctemplar.com or decrypter0203@gmail.com. It is stated that a ransom must be paid in two days after encryption because on the third day decryption will become impossible. There are no other tools that could decrypt files encrypted by Polleryou, at least not at the moment. It means that Polleryou's developers are the only ones who have the right decryption tool. However, they should not be trusted, it is very likely that they will not send that tool even if victims will pay them a ransom. It is common that victims who pay a ransom get scammed. In most cases the only way to recover files without having to use tools that usually can be provided only by cyber criminals is to restore them from a backup. It is worthwhile to mention that files remain encrypted even after removal of ransomware. By uninstalling ransomware from the operating system victims only prevent it from causing further encryptions.

There are many other ransomware-type programs, some examples are Prometey, SDfghjkl and Iwanttits. Typically, software of this type is designed to make sure that victims could not access their files without having to decrypt them with tools that can be provided only by its developers fist. As a rule, victims are provided with instructions on how to purchase them (and/or contact cyber criminals) in a created and/or displayed ransom note. Two main variables usually are size of a ransom and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt files. In most cases files can be decrypted without tools that can be purchased from cyber criminals only if ransomware has some bugs, flaws, or other vulnerabilities. Unfortunately, it does not happen often and victims can recover files for free only by restoring them from a backup. That is why it is important to have data backed up and store it on a remote server like Cloud and/or unplugged storage device.

How did ransomware infect my computer?

In most cases cyber criminals spread various malware through Trojans, spam campaigns (emails), untrustworthy software download channels, unofficial activation ('cracking') tools and fake software updaters. Trojans are malicious programs that can do damage to the operating system only if they are already installed on it. When installed, they infect systems with other malicious programs, e.g., ransomware. Spam campaigns are used to proliferate malicious programs via attachments or website links. Cyber criminals send emails with malicious files attached to them (or web links that are designed to download malicious files) and hope that someone will open that attachment (or downloaded file). Some examples of files that they usually attach are Microsoft Office documents, executable files (like .exe), archive files (like RAR, ZIP), JavaScript files and PDF documents. If opened, those attachments (or files) install ransomware or some other high-risk malware. Operating systems can be infected through unreliable download sources, tools as well. For example, through Peer-to-Peer networks (like torrent clients, eMule), third party downloaders, unofficial websites, free file hosting websites, freeware download pages and other similar sources. Typically, cyber criminals upload malicious files that are disguised as legitimate, harmless and wait for someone to download and open them. Various unofficial activation ('cracking') tools that supposed to bypass activation of some licensed software often infect systems with malware too. Quite often these tools are designed by cyber criminals and install malware instead of activating licensed programs. Fake software updaters usually infect systems by installing malicious software instead of updating the installed one, or by exploiting bugs, flaws of outdated software.

How to protect yourself from ransomware infections?

If an email is received from unknown, suspicious address, it is irrelevant and contains some website links or attachment, then its contents should not be opened. Quite often such emails are sent by cyber criminals who seek to trick recipients into installing malicious software. Installed software must be updated through implemented functions and/or tools that are designed/provided by official developers. None of the third party tools should be used for that. The same applies to software activation. Besides, it is not legal to activate programs with various third party ('cracking') tools. Files and programs should be downloaded from official websites, other sources, tools that are mentioned in the paragraph above can be (and often are) used to spread malicious programs (files). Operating system should be scanned for threats with a reputable antivirus or anti-spyware software and it should be done regularly. Also, it is important to make sure that installed software of this type is always up-to-date. If your computer is already infected with Polleryou, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 Polleryou 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 Polleryou 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 Polleryou 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 Polleryou, 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 Polleryou 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.

Controll Folder Access

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:
