Brrr ransomware virus

The item is about Brrr ransomware that infects users' PC around the world, and encrypts their files. In this item you will find full info about Brrr's essence, and the removal of Brrr from the workstation. In addition, we will explain how to restore the encrypted files and is it possible.

Brrr is the undesired software infecting workstations mostly with help of e-mail spam and Trojans. Also, web-criminals use zero-day vulnerabilities to take control over the system, but major software companies promptly fix them. After the infection, ransomware inspects the hard disc to find the files to be encrypted and their general worth. Nowadays, any modern ransomware can cypher image, text, audio and video files in all known formats. Ransomware cyphers all folders, but those that look like business documents go first. All software on PC will be untouched because fraudsters want only information. Encryption is carried out through world-known AES and RSA algorithms, and its intricacy is so above the average level that it can't be bruteforced. This is the foundation for such a stunning efficiency of this kind of viruses in last years: an ordinary PC operator, even having a pretty high knowledge of the PC, will never restore the data, and will be forced to pay the price. The sole method to get back the data is to find the scam site and obtain the master key. Also there's a chance to withdraw the keys through faults in viruse's program code. The encrypted files get.YYY extension, and the amount of ransom is ZZZ.

For any sorts of ransomware, one statement is correct: it's much easier to dodge it than to neutralize its fruits. For ransomware this is very important, because, unlike normal suspicious programs, when you eliminate ransomware from the PC, the effects of its actions won't vanish anywhere. To protect yourself, you must keep in mind a few simple principles:

    • Keep an eye on the state of your workstation. It consumes a lot of hardware resources to encode the data. If you mention a sudden fall in PC capacity or notice a unwanted process in the Process Manager, you can unplug the machine, load it in safe mode, and run the antivirus. Naturally, some information will be corrupted, but the other part of them will be safe.
    • Heed to the pop-up windows. The easiest method of file restoration is the recovery through Shadow Copies, so Web-criminals have added the removal of SC into the default functionality of viruses. Anyway, deletion of copies requires admin rights and acceptance from the user. So, if you do not accept alterations from a suspicious program at the right time, you will keep the way to recover all corrupted information for free.
    • Closely inspect your mailbox, specifically the messages that have files attached to them. If this message comes from an unknown address and it notifies about receiving some prize, a lost parcel or something like that, this might be ransomware. The #2 efficient type of these letters is a forgery for biz correspondence. It is natural to take an interest and read the letter even if it's sent to the wrong address, but don't forget that a single click on the viral file can cost you a lot of headache, money and time.

Brrr elimination isn't the happy end - it's just a one move from many until the complete data recovery. To decrypt the data you'll need to follow the instructions in the next section of our article. To deelete the ransomware, user needs to load the system at safe mode and run the scanning with AV-tool. We do not recommend trying to eliminate ransomware manually, since it has numerous defensive features that can counteract you. Modern malware can completely remove encrypted data, or part of it, when trying to uninstall the virus. To avoid this, abide to the tips under this paragraph.
