OS(es) Affected: Windows

The 'avastvirusinfo@yandex.com' Ransomware is a new version of the Xorist Ransomware, a Trojan that uses a TEA or XOR-based method of encrypting and locking your local files. A significant missing feature from this family, including the 'avastvirusinfo@yandex.com' Ransomware, is the lack of the preservation of a decryption key for unlocking the damaged content. Use anti-malware programs to, hopefully, block and remove the 'avastvirusinfo@yandex.com' Ransomware, and backups to keep it from causing any problems that you can't undo.

A Fake Avast Assistance Throwing You a Fake Lifeline

With more Trojans requiring complicity from their victims to turn a profit, con artists are continuing to experiment with new and old combinations of persuasive tactics with a foundation of real attacks. The 'avastvirusinfo@yandex.com' Ransomware offers a look at two distinct ways in which trusting a Trojan's administrator can backfire on the victim, even when it comes to a simple goal like disinfecting your PC and reversing the side effects of that infection. The Trojan is a member of the comparatively small Xorist Ransomware family, whose latest activities are traceable to Russia.

The 'avastvirusinfo@yandex.com' Ransomware enumerates your local drives for files matching its list of content to encrypt, which contains nearly two thousand formats, including documents, spreadsheets, audio and compressed archives. The 'avastvirusinfo@yandex.com' Ransomware also encodes any files that don't use extensions to denote their formats. The Trojan does add an extension to each filename, but the string is a series of eight random characters, instead of a set phrase (such as '.encrypted' or '.locked').

In the accompanying text message that the Trojan creates afterward, the 'avastvirusinfo@yandex.com' Ransomware's authors pose as technical support from the Avast cyber security company. Although they offer to decrypt your files for a cash payment, malware experts note that the 'avastvirusinfo@yandex.com' Ransomware doesn't save or upload its key. This inaction makes any encrypted files unusable permanently without recovering them through a third-party decryptor (such as the one currently hosted by Emsisoft).

Implementing Real Recovery Strategies against Fraudulent Software

In addition to using a brand name to solicit a degree of trust that's unearned, the 'avastvirusinfo@yandex.com' Ransomware offers a sharp insight into the operating methodology of threat authors presenting false choices to their victims. With the presence of freeware decryption tools, most PC users should be able to recover from the 'avastvirusinfo@yandex.com' Ransomware without losing their files. By contrast, paying the ransom gives no advantages or data recovery features.

However, the 'avastvirusinfo@yandex.com' Ransomware also offers some unique challenges for an infected PC compared to Trojans not hailing from the Xorist Ransomware family. This Trojan damages more file types than most threats of its kind and may corrupt the Windows operating system incidentally. If Windows fails to boot after an 'avastvirusinfo@yandex.com' Ransomware infection, you should use a DVD or USB-based recovery device to launch a non-compromised version of the OS. If using Safe Mode, malware experts recommend the 'with networking' option to allow your anti-malware products to update themselves and optimize deleting the 'avastvirusinfo@yandex.com' Ransomware accurately.

The 'avastvirusinfo@yandex.com' Ransomware's low detection rates belie the legitimate danger and system damage this Trojan is capable of causing. However, as with any file encryptor Trojan, educating yourself and practicing safe internet behavior can keep you from making mistakes not readily rectified, both for your files and your bank account.
