What is AvastVirusinfo ransomware virus?

AvastVirusInfo ransomware corrupts victim’s files for good, but still wants a ransom

AvastVirusInfo virus is a scammy and malicious program, which poses as a working ransomware[1] meanwhile it is a poorly programmed piece of malware. It has been discovered that AvastVirusInfo malware is a new version of Xorist ransomware.[2] Just like any other ransomware, AvastVirusInfo encrypts[3] nearly all files on the system and then asks the victim to pay a ransom, however, even if the victim does so, the virus authors will NOT provide the decryption key. This virus completely damages files and makes them useless, so do not waste your money by paying the ransom to cyber criminals. The ransomware targets Russian-speaking users and can be recognized from file extensions that it adds to each encrypted file – this particular virus appends .[8 random chars] extension to every corrupted record.

AvastVirusInfo ransomwareIf your files were corrupted by AvastVirusInfo ransomware, do not pay the ransom! Cyber criminals will not provide you with the decryption key. It is also important to mention that AvastVirusInfo ransomware is NOT related to Avast Antivirus anyhow. It is unclear why ransomware authors like to pretend that they are related to computer security firms. The ransomware corrupts the system and creates a ransom note called КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt, (English version: HOW TO DECRYPT FILES.txt). The ransom note says that all files were encrypted and that if the victim wants to recover them, he needs to pay $15 to authors of the virus. These novice ransomware crooks ask the victim to contact them via email – avastvirusinfo@yandex.com. This email address is where the name of this ransomware originates from. However, we repeat – do not pay the ransom and do not bother yourself writing to cyber criminals – they cannot help you to restore your files. Malware analysts have analyzed this notorious program and discovered that it targets over 1791 different file types (the virus decides to encrypt a file if its extension matches one from its target list). If your files were encrypted by this ransomware, follow the instructions provided below this article to remove AvastVirusInfo malware in the right way. You will need an anti-malware program for AvastVirusInfo removal – please do not try to uninstall this virus on your own, because this way you can only damage the system if you accidentally delete a few wrong files. For virus removal, we believe ReimageIntego is the best option.

How can I get infected with this virus?

AvastVirusInfo ransomware is dangerous, and you should do everything to stay away from it. Such viruses are mostly distributed via email, pirated software packs, or compromised websites[4]. The best way to protect yourself from ransomware viruses is to install and always fulfill your anti-malware software with the latest updates, as well as have a data backup to use in case a ransomware manages to slip into your PC. You can avoid ransomware by not opening suspicious emails sent by strangers, also not browse shady third-party websites. Sadly, it gets harder and harder to keep up with the latest malware distribution tricks and recognize phishing[5] or compromised websites, so we assume the anti-malware software is the key to a safe computer.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
