Adr virus Removal Guide

What is Adr ransomware?

Adr ransomware – cryptovirus that replaces file names by adding an appendix too

Adr ransomwareAdr ransomware - a virus that fully renames files after encryption.

Adr ransomware is a computer virus that demands a ransom after it encrypts all non-system files on an infected computer. These are the main principles of how all ransomware works. The few differences might be with the ransom amount, ransom notes, and the file extensions that are appended to all personal data.

When Adr ransomware virus is encrypting data it changes the original names of the files with a random sequence of characters and then appends a .adr extension. Usually, cryptoviruses don't modify the original filenames, only append from one to three extensions to them, e.g., Lisp ransomware just adds .lisp to all non-system data.

When all files are locked, Adr ransomware drops a ransom note in the C:\Users\[Username] folder, named DesktopDECRYPT_ME.TXT. Within the note, the cybercriminals urge the victims to open a ransom note named DECRYPT_ME.TXT, that's placed on the infected computers' desktop. So clearly the virus isn't working as it's supposed to.

Virus removal Cryptoviruses like Adr ransomware should be eliminated from the infected devices with the help of reliable anti-malware software
System fix When Adr ransomware removal is completed, victims of this cryptovirus should use the FortectIntego app to perform a full system cleanup, i.e. remove all modifications that the virus has done to system files and settings

The ransom note itself is short and uninformative. The developers of Adr ransomware only state that all files of the victim are encrypted and that the only way to regain access to them is to buy their “service”, i.e., their decryption tool. Then they provide one email to establish contact –

Usually, creators of ransomware, like Sglh or Fireee, are more instructive in their ransom notes. They specify ransom amounts and preferred payment options. Provide semi-reassuring free decryption of a few files guarantee to prove that they really have the necessary tools for decryption. Or threaten the victims not to recover the .adr files or try any third-party software to decrypt them.

As always, we strongly advise against any contact with the cybercriminals. All malware should be dealt with accordingly – deleted with a powerful anti-malware app. We recommend SpyHunter 5Combo Cleaner and Malwarebytes software to remove Adr ransomware from infected devices with a push of a button.

Following Adr ransomware removal, users should listen to experts[1] and perform a full system scan with the FortectIntego tool to make sure the system files and system settings weren't altered. If they were, this app will revert any of these changes and get your device back on track.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
