Tips To Delete RAGNAROK (.thor) Ransomware

RAGNAROK (.thor) Ransomware is a kind of very dangerous file-locking malware and a new variant of Ragnarok ransomware. It often penetrates the Windows computers by stealth without users’ approval and then encrypts their crucial files and data stored inside their systems. This precarious crypto-virus has been found to be using the combination of AES and RSA cryptographic algorithms to lock the targeted files and makes them completely inaccessible for the victims. After that, it starts blackmailing users for the decryption tool. This notorious parasite mainly targets Windows OS based computer systems and is able to compromise all versions of Windows including the latest Win 10.

Depth Analysis of RAGNAROK (.thor) Ransomware:

RAGNAROK (.thor) Ransomware can infect almost all types of data including videos, audios, pictures, documents, spreadsheets, presentations etc. and make them completely useless. All the compromised files are marked with a random character string and the “.thor” extension. After completing the encryption process, this hazardous threat drops a ransom note named “!!Read_me_How_To_Recover_My_Files.html” in each affected folder and informs victims that their data have been encrypted. It also states that in order to regain access to the locked files, victims need to purchase the decryption software from the attackers.

The price of the tool is $980 however, if the users contact the criminals within 72 hours via the provided email address, then it will be halved and they only have to pay the hackers $490 in BitCoins. You can also test the decryption by sending one infected file to the RAGNAROK (.thor) Ransomware authors but that should not contain any valuable information.

Should You Pay The Ransom?

Nobody wants to lose their important files and documents and hence, many victims agree to deal with the attackers but often end up losing both files as well as money. Keep in mind that the only motive of such people is to extort illicit revenues from the victimized users. They will never decode the encrypted files even after taking the ransom. Most of the times, hackers ignore the victims once the ransom is paid or deliver rogue software in the name of functional decryptor. So, never make any sort of payment to the hackers and try to perform RAGNAROK (.thor) Ransomware from the machine as early as possible.

How To Recover The Infected Files?

Paying the demanded fee to the crooks is not a clever thing to do under any circumstance as it will only motivate them to create and drop more such viruses inside for further profits. Instead, you should try to restore the compromised data using the backups that you have saved on any external drive. If you don’t have a proper backup, you can try an appropriate file-recovery program.
