DeadSec-Crypto v2.1 Removal Guide

What is DeadSec-Crypto v2.1?

The main traits of a deceptive DeadSec-Crypto v2.1 virus

DeadSec-Crypto v2.1 virus is a new cyber infection which infiltrates computers and generates a lock screen [1] preventing victims from accessing their files. In other words, DeadSec-Crypto is not an encryption-based virus which encrypts the actual contents of the files. The creators of this ransomware merely imitate the workings of the real encrypting infections without doing much of the programming work themselves. A stand-out feature of this ransomware is the fact that it is targeted at Brazilian and Portuguese users since the ransom note is displayed in the Portuguese language. So, if you live in either of these countries, stay cautious. Keep in mind that the scammers will try to make the scam look more convincing, by appending files with .locked extensions, though their structure does not change. They may also name the virus executable as WindowsApplication1.exe to make it seem like a legitimate Windows application. More experienced users will notice this trap right away, but the problem is that the criminals usually aim for the less tech-savvy people, who are easier to convince that their data has been encrypted and that they must pay the around 900 dollar ransom for its “recovery.” Nevertheless, the hackers don’t make it easy for the inexperienced users to make the payment. They demand the ransom to be transferred in Bitcoins [2] which have to be purchased with real money first. The transaction screenshot must be sent to the criminals by email, and only then victims receive the recovery key. But all that’s just theory. In reality, the extortionists wait for their Bitcoin accounts to fill up and then vanish. Luckily, DeadSec-Crypto v2.1 removal can solve these issues. The problems should disappear as soon as the malware is out of the system. You will fix your PC quicker with the help of FortectIntego.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
