The Buddy Ransomware is a file encrypting Trojan that holds your data up for ransom so that the Buddy Ransomware can receive Bitcoin payments. Since ransoming files affected by the Buddy Ransomware may not provide the necessary decryption service to restore your information, malware researchers typically don't encourage that you pay the fees endorsed by these Trojans. Instead, employ security procedures as necessary for regaining access to your PC, and run anti-malware products capable of detecting and then uninstalling the Buddy Ransomware.

The Buddy Who's Always Asking You for Money

The Buddy Ransomware is a new variant of file encryption threats operating under the same principles as most file encryptors. The Buddy Ransomware installs itself through non-consensual methods such as in-browser scripts or mislabeled e-mail attachments, scans for non-critical file data and then encrypts your documents, images, audio files and other information. All encryption targets are identifiable currently by looking for the '.cry' extension that the Buddy Ransomware applies to each encrypted file. Like other file encryptors, this automatic name change doesn't correspond to any effort of converting the files to another format. Renaming your files or removing the extensions will not remove the Buddy Ransomware's encryption, which modifies the structure of each file's internal data.

There are some minor innovations in current samples of the Buddy Ransomware. Unfortunately, these changes all were for improving the usability for its ransom process. Unlike some simplistic file encryptors, the Buddy Ransomware delivers a pop-up ransom message that includes a built-in interface for purchasing Bitcoin currency (slightly under 300 USD for its recommended ransom). It implies that the Buddy Ransomware includes, currently, an automated routine for decrypting your files within minutes after receiving this payment, although malware experts can't confirm the presence of this feature.

Telling Your Trojan 'Buddy' to Go Away

Since the Buddy Ransomware can't collect payments from damaged PCs, files that are essential for your operating system are unlikely of being encrypted by this threat. As a result, standard strategies for long term data protection, such as using USB-based backups or cloud storage services, can provide your files with easy means of remaining safe from the Buddy Ransomware, even if you can't remove its encryption. Malware experts also stress the ongoing development of free decryptor utilities for threats like the Buddy Ransomware, which you always can download from links provided by reputable security companies.

The Buddy Ransomware and other PC threats of the same type often implement their ransom messages in conjunction with attacks that lock your desktop or, otherwise, prevent you from accessing your security software. To work around these attacks, reboot your computer (through a removable drive, if necessary) and use your operating system's Safe Mode feature. Launching your OS with Safe Mode enabled will reduce the possibility of threats also launching, which can help your anti-malware programs delete the Buddy Ransomware safely.

As always, removing the Buddy Ransomware doesn't include decrypting any files, which is a separate process that requires specific, dedicated applications. If the decrypting becomes difficult or impossible, malware experts can guarantee the efficacy of restoring it from backups.
