Effective measures to delete Jigsaw (Chaos) ransomware

Jigsaw is a new variant of Chaos ransomware that uses the AES algorithm to encrypt various files stored on computers. Simply said, it is recently detected file locker virus that renames files by appending a randomly generated extension to their filenames. After encryption, this ransomware creates the “read_it.txt” file as its ransom note to inform you about the infection and payment details.

It will state that all your files are encrypted by a powerful algorithm and can only get unlocked via private decryption key. It will ask you to pay $300 in Bitcoins to buy the key to the provided BTC wallet address. This dubious rogue ransomware will give you some time to pay the ransom otherwise it will delete all your files.

Despite this, victims are encouraged not to rename the affected files or try to decrypt those files manually using third-party software as it might leads into permanent data loss. In most cases, it has been noticed that victims cannot recover files without paying a ransom. It can be avoided only when there is a free decryption tool available on the internet.

Therefore, ransomware victims are highly advised not to pay money to them because there is no any proof that the attackers will send a decryption tool. Instead of paying/contacting to the crooks, make sure to remove Jigsaw (Chaos) ransomware using some reputable antivirus tool from the computer. Just after that, restore files using the existing backups or any other data recovery tools.

If you run outdated or obsolete software on your computer, then you are in risk of ransomware because the software developers are not putting out security updates anymore. To remove abandonware and replace it with software still being supported by manufacturer.
