Jerry_glanville ransomware removal instructions

What is Jerry_glanville ransomware?

Jerry_glanville (also known as Balaclava) ransomware was discovered by dnwls0719. Like many other programs of this type, it encrypts victim's files, changes their filenames and creates a ransom note. Jerry_glanville renames files by appending the "jerry_glanville_data@aol.com" email address to their filenames. For example, it renames "1.jpg" to "1.jpg.jerry_glanville_data@aol.com", and so on. It creates a ransom note named "HOW_TO_RECOVERY_FILES.txt", this file contains instructions on how to contact cyber criminal who designed Jerry_glanville.

As stated in the "HOW_TO_RECOVERY_FILES.txt" ransom note, Jerry_glanville's developers are the only ones who can help victims to recover (decrypt) encrypted files. In order to get instructions on how to purchase a decryption tool victims have to write an email to jerry_glanville_data@aol.com and provide the appointed personal ID. Also, victims can send them one encrypted tile that they should decrypt for free. However, we do not recommend to pay these cyber criminals a ransom, it is very likely that they will not send a decryption tool even after a payment. It is common that victims who pay a ransom get scammed. Unfortunately, there are no other tools that could decrypt files that were encrypted by this ransomware, at least not at the moment. Typically, the only way to recover data for free in such cases is to restore it from a backup. It is worthwhile to mention that files remain encrypted even if victims uninstall ransomware from a computer, however, its uninstallation prevents it from causing further encryptions.

A couple examples of other programs of this type are DeathHiddenTear, EncoderCSL and .Adame (Amnesia). Most of these programs are quite similar: they encrypt data and create a ransom that contains instructions on how to contact cyber criminals, pay a ransom and/or other details. Most common and main variables are price of a decryption tool and/or key and cryptographic algorithm (symmetric or asymmetric) that that ransomware uses to lock (encrypt) files. Usually it is impossible to decrypt files without tools that only cyber criminals behind a particular ransomware have. It is possible only in cases when ransomware has some bugs, flaws, is still in a development state. In most cases data loss can be avoided fro free only by restoring files from a backup. Therefore, it is recommended to always have a data backup and store it on a remote server and/or unplugged storage device.

How did ransomware infect my computer?

In mot cases cyber criminals spread various malware (including ransomware) through spam campaigns (emails), software 'cracking' tools, Trojans, untrustworthy software download channels and unofficial software updaters. One of the most common ways to trick users into installing malware on their computers is by sending emails that contain malicious attachments. When recipients open/execute them, they cause installation of malicious software. Some examples of attachments that cyber criminals usually send are Microsoft Office documents, executable files (like .exe), PDF documents, archive files like ZIP, RAR and JavaScript files. Various third party activation ('cracking') tools can lead to installations of high-risk malware too. People who use such tools seek to bypass activation of licensed software, however, quite often they cause installation of malicious software instead. Trojans are malicious programs that often are designed to cause chain infections (spread/install other programs of this type). However, Trojans can cause it only when they are already installed. Peer-to-peer networks (like torrent clients, eMule), third party downloaders, installers, freeware download websites, free file hosting websites are channels that cyber criminals often use to host malicious files. By opening files dowloaded through such sources users risk to install some malicious software. Fake software updaters, if used, either exploit bugs or flaws of some outdated software that is installed on user's operating system or install malicious software instead of updates, fixes.

How to protect yourself from ransomware infections?

All files and software should be downloaded from official websites and via direct links. Various third party downloaders, installers, unofficial websites, Peer-to-Peer networks and other similar channels should not be trusted/used. If a received email is irrelevant, sent from unknown, suspicious address and contains some attachment and/or website link, then it may be sent some cyber criminals. Such emails should be analyzed and their contents should not be opened without being sure that it is safe. Installed software must be updated with implemented tools and/or functions that are provided by official software developers. It is not safe to use third party, unofficial tools for that. The same applies to software activation. Besides, it is not legal to use third party tools to activate any licensed software and such tools can be used to spread malicious programs. One more important thing is to regularly scan the operating system for threats with a reputable antivirus or anti-spyware suite and always remove detected threats as soon as possible. If your computer is already infected with Jerry_glanville, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
