BlockFile12 virus Removal Guide
What is BlockFile12 ransomware virus?
BlockFile12 ransomware virus takes files to hostage and demands to pay the ransom
BlockFile12 is a crypto-malware that encrypts files on the affected computers and distorts file names. After the attack, each of the targeted documents, multimedia files, and other data includes a contact information and .block_file12 file extension. Ransomware uses this scheme for renaming affected files: .===email@example.com===.block_file12. Following data encryption, ransomware drops a ransom note on the desktop which is called HOW TO DECRYPT FILES.txt. The threatening letter explains that victims have to contact cyber criminals via firstname.lastname@example.org email address in order to get instructions for data recovery. However, having conversations with crooks is not a good idea. They will probably use some psychological terror and blackmailing techniques to convince you to transfer particular amount of Bitcoins. The size of the ransom is unknown. It seems that cyber criminals decide the worth of the files individually. However, it doesn’t matter how much money they ask; you should not make the payment. Remove BlockFile12 from the computer and save your money. Cyber criminals may not provide you promised decryption software, but they will gladly use your money for future projects.
Apart from corrupting files, BlockFile12 might also open the backdoor for other malware. Thus, the longer you let it stay on your computer, the bigger risk you take to encounter other ransomware or data-stealing Trojans. If you are having thoughts about paying the ransom, we want to discourage you from making the wrong decision. Transferring Bitcoins will not remove ransomware from the computer. Besides, you may not get back your files because cyber criminals do not always keep up their promise. If you have data backups or at least some of your files saved in external or online storage, you have everything what you need. If not, you should try our alternative recovery options that are absolutely safe. However, you should think about data recovery after BlockFile12 removal. Thus, if you got infected, install ReimageIntego, scroll down to the end of the article, and learn how to clean your device.

The main ways how ransomware infiltrates computers
BlockFile12 ransomware might get into the PC using several techniques. There’s no doubt that cybercriminals use social engineering techniques and spread numerous malicious emails that include infected attachments or links. Such emails might look like sent from governmental institutions, banks, delivery services, etc. The letter itself might inform about serious problems or necessity to check some information, and ask to open the attachment or visit a particular website. Once you do that malicious payload is downloaded and executed on the system. Furthermore, BlockFile12 hijack might also occur when you visit crafted website, click on a malware-laden ad or download bogus software. Therefore, it’s crucial to avoid visiting high-risk Internet sites (e.g. adult-themed, gaming, gambling, etc.) and clicking online ads. We want to point out that malicious ads might also be placed on legitimate websites as well and barely differ from safe ads. Thus, before clicking that ad offering amazing shopping deal, you should think twice whether it’s actually worth taking a risk.

How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
