.blower ransomware removal instructions
What is .blower?
There are plenty of ransomware-type infections and .blower is one these malicious programs. As with most rogue software of this type, it is used to encrypt data and blackmail people who have computers infected by it (by demanding ransom payments). They encourage victims to purchase a decryption tool. Note that this malicious program belongs to the Djvu ransomware family and was discovered by dis. It adds the ".blower" extension to each encrypted file. For example, "1.jpg" becomes "1.jpg.blower". Note that .blower also creates a "_readme.txt" file (a ransom message).
The message within the "_readme.txt" file informs victims that all files (including photos, databases, and other documents) were encrypted with the strongest encryption, which requires a unique key. According to .blower's developers, the only way to decrypt encrypted data is to purchase a decryption tool from them. They offer free decryption of one file as 'proof' that they have a valid tool capable of decryption. To receive this decryption tool, users are encouraged to pay these cyber criminals $980. They offer a 50% discount for those who make contact within 72 hours (the decryption tool would then cost $490). They provide two email addresses for this purpose: email@example.com and firstname.lastname@example.org. Note that, even if they have a decryption tool, it is unlikely that they will provide it. In many cases, cyber criminals ignore victims once ransoms are paid/transferred. Unfortunately, they usually encrypt data with cryptography algorithms (symmetric or asymmetric) and thus files cannot be decrypted without using a specific (decryption) tool. In most cases, ransomware victims are encouraged to contact cyber criminals (the developers). There is no information indicating that there might be tools capable of decrypting .blower encryption free of charge. Typically, the best solution in these cases is to use an existing data backup and restore everything from there.

There are many ransomware-type infections, most of which are very similar. Some other examples include CryptoID, 888, and Cosanostra. Most of these malicious programs have the same functions: to encrypt data, allow developers to make ransom demands, and blackmail victims. The main variables are usually cost of decryption tool (ransom size) and cryptography used for data encryption. Despite any similarities or differences, these programs all encrypt data using cryptographies that are impossible to 'crack' without using a specific tool, unless ransomware is not fully developed or contains bugs/flaws. Unfortunately, only cyber criminals can provide these tools. To avoid data loss caused by such computer infections, maintain data backups and store them on unplugged storage devices or remote servers.
How did ransomware infect my computer?
It is not known exactly how .blower's developers proliferate this malicious program, however, cyber criminals often use email (spam) campaigns, Trojans, dubious software download sources, fake software updating tools and software cracking tools. Spam campaigns are used to proliferate computer infections by sending emails that contain malicious attachments: Microsoft Office documents, PDF files, archive files (like ZIP, RAR), executable files (.exe) and so on. Cyber criminals succeed in infecting computers if people open these attachments. By opening malicious attachments, many users trigger download and installation of ransomware or other malicious programs. Trojans are used to cause chain infections: if a Trojan is installed, it downloads and installs additional malware. Untrustworthy software download sources such as freeware download websites, free file hosting websites, Peer-to-Peer networks (like torrents, eMule and other tools), third party downloaders/installers are often used to present malicious software as legitimate. Any of these tools can cause unintentional installation of computer infections. Fake software updaters cause computer infections by downloading malware rather than the promised (expected) updates or by exploiting outdated software bugs/flaws. Software cracking tools often install malicious programs rather than (illegally) activating software or operating systems.
How to protect yourself from ransomware infections?
To prevent computers infections by ransomware (or other high-risk computer infections), download, install, update software and browse the internet carefully. Avoid third party software downloaders/installers or other dubious sources mentioned earlier. Download software using official and trustworthy websites and direct links. Furthermore, avoid unofficial/third party tools to update software. The best way to update software or operating systems is through implemented functions or tools provided by official software developers. Be careful with attachments presented in emails. Avoid opening attachments (or web links) that are presented in emails received from unknown/suspicious addresses or irrelevant messages. Note that activating software or operating systems using software cracking tools is illegal. Furthermore, using them can cause computer infections that might lead to financial loss or other problems. Finally, have reputable anti-spyware/anti-virus software installed and enabled. These tools can detect threats early and prevent them from doing any damage. If your computer is already infected with .blower, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

As with most of ransomware from Djvu family, .blower also displays a fake Windows update pop-up during the encryption:
IMPORTANT NOTE! - Ransomware-type infections from Djvu malware family are designed to add a number of entries to the Windows hosts file. The entries contain URLs of various websites, most of which are related to malware removal. This is carried out with the intention of making users unable to access malware security websites and seek help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).
