Theva Ransomware (.theva File Virus) Removal Guide

Theva ransomware is a nasty malware infection that encrypts files on the targeted computer and demands ransom money to give decryption keys. It encrypts files by appending the “[sql772@aol.com].theva” extension to the original filenames.

For example, a file named “myphoto.jpg” will be changed into “myphoto.jpg.[sql772@aol.com].theva”. This is a locked file and cannot be accessed without the decryption key. Once the encryption of all the files is done, it replaces the desktop wallpaper with a ransom message and drops the note “#_README_#.inf” on the computer.

Threats like Theva File Virus keep getting back on the PC if all associated files are not removed. So you are advised to use a powerful Malware Removal Tool to run a thorough scan of your PC and delete all threats at once.

What is Theva Ransomware?

Theva file virus is a dangerous ransomware that secretly infiltrates your PC and encrypts your files. It uses a powerful encryption algorithm to render all your files inaccessible. Some changes in the extension of the file are also made as mentioned above. A ransom note is also left on the system after encryption.

The ransom note clearly instructs victims to communicate with cyber criminals to buy decryption tools. If victims choose not to pay the ransom money, then their files will remain locked and can also be leaked online. It is a serious threat that can also turn the targeted computer useless for some time.

What you can do?

In most cases, it is impossible to regain access to locked files without a decryption key. It means victims are forced to contact the makers of the virus to purchase the decoder. But it can open doors to even more serious problems. Decryption tools often leave Trojan horses to steal the personal and financial details of users.

Cases of fraud and decryption tools not working have also been found very often. Cybercriminals stop answering emails once they get paid. They always demand ransom money through cryptocurrency which cannot be tracked. So it could be highly risky to pay ransom money to get your files back.

Removing .Theva File Virus can prevent further encryption of your data and damage to your PC. Unfortunately, the removal of this threat will not bring your files back. However, if you have any backup of your files then you can recover all your files.

  • Do not download or install any type of pirated software, games, or illegal patches. Avoid using shady sites to acquire freeware programs because they often use software bundling. Never install a program that asks you to inactivate your anti-virus software.
  • Avoid opening spam emails from unknown senders.  Always scan all the email attachments before opening them. Never click on any suspicious links with some too good to be true offers.
  • Connecting your PC or mobile devices to unsafe public Wi-Fi is not a good idea. You can also avoid unwanted threats coming from malicious sites by using a VPN to spoof your connection.
