Jigsaw 4.6 virus Removal Guide

What is Jigsaw 4.6 ransomware virus?

The imperfect Jigsaw 4.6 ransomware is on the hunt for victims

Jigsaw 4.6 virus is a brand new variant of Jigsaw ransomware. Malware analysts have spotted the first samples of Jigsaw 4.6 ransomware in March 2017. The initial design of the virus has changed, and now the malicious program uses a different picture of the Jigsaw Killer[1] (or John Kramer) for the lock screen. It might be that the author of this virus believes that users who do not care to protect their computers deserve to be infected, just like John Kramer (the character of Saw movie) believed that people who do not appreciate their lives do not deserve to live. The current version of Jigsaw 4.6 malware lacks the programming code that makes the virus capable of encrypting data[2] on victim’s computer; however, the virus has a lock screen, plays an audio message, and displays message boxes. We assume that the virus is going to be improved and start encrypting victims’ files in the future. However, the history of Jigsaw malware shows that these viruses are full of bugs that allow malware analysts comprehend their functionality easily and create free decryption tools for the victims[3]. Jigsaw 4.6 ransomware virusOur expert demonstrates the lock screen that Jigsaw 4.6 ransomware virus displays. The virus doesn't encrypt victim's files, but says that it does.

The malicious program launches a lock screen as soon as it enters the computer system, and the lock screen informs the victim that the “computer files have been encrypted by Jigsaw Ransomware version 4.6 […] Photos, videos, documents, ect….” According to the message provided by the ransomware, criminal actors want to receive $150 as a ransom (the message asks for 0.4 Bitcoins[4], which at the moment equals to $496 USD) to a provided Bitcoin wallet address, which appears to be invalid. Besides, the virus threatens to erase victims files one after another if one attempts to avoid paying the ransom. The virus promises to restore victim’s files as soon as the transaction gets completed; however, we do not advise you to waste your time buying Bitcoins because this ransomware does not corrupt your files! All you have to do is to remove Jigsaw 4.6 ransomware using a professional malware remover, for instance, ReimageIntego or SpyHunter 5Combo Cleaner. Before you try to download and run one of these programs, carry out Jigsaw 4.6 removal instructions provided below the article. The tutorial given below can help you to prepare your computer for ransomware elimination.

Distribution of Jigsaw 4.6 ransomware

Almost all ransomware viruses are distributed using same trickeries – the only thing that differs is the complexity of them. To put it simply, the more experienced cyber criminals are, the more sophisticated and modern ransomware distribution methods are used. For example, highly complex ransomware viruses such as Cerber or Spora are distributed via malvertising, exploit kits[5], while the majority of less-professional malware developers rely on the good old mail spam technique. This method is one of the most basic and efficient ones – scammers just create legitimate-looking emails and attach one or a couple of files to it. The message in the electronic letter kindly suggests opening attached files and viewing contents of them, sadly, this is a straightforward way to infect your computer with ransomware. Please, stay away from emails sent by unknown people, and protect your computer with proper security tools. It is also highly advisable to create data backups.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
