What is Ransomware? Ransomware can infiltrate your system without your noticing it after you click to run a file you have downloaded from a dangerous spam e-mail. This is a major hit to your computer because this ransomware can encrypt your photos, videos, archives as well as program files. You will only be able to recover them and use them again unless you get hold of the decryption key. This key is of course in the hands of the cyber criminals who attacked you in the first place. They usually keep this unique key on a secret server. The only problem is that such crooks may have to shut down the server to cover their tracks, i.e., security reasons and thus the communication with the infection would break and your decryption key would be lost forever. In other words, even if you were ready to pay the several hundreds of dollars worth of ransom fee, you may not get the software and the key either. Our malware specialists at suggest that you remove Ransomware right now if you want to save what is left of your system.testtest

Where does Ransomware come from?

This ransomware seems to follow suit and travels the web as a malicious file attachment in spam e-mails. Many users think that just because they have a spam filter, they are all safe. Well, such a spam may even avoid detection and end up in your inbox. However, this spam can be so convincing that finding it in the spam folder would still make it quite dangerous because it could easily fool you into opening it. These criminals may use totally legitimate-looking e-mail addresses for the sender, which may also include local authorities, for instance. Then, the subject may also strike you as important since it could be anything, such as an overdue speeding ticket, an issue with your credit card details with regard to a flight ticket booking, an undelivered parcel problem, and so on. If you find such a mail among your e-mails no matter in which folder it lands, you would be quite likely to want to see its content, right? Unfortunately, wrong.

After you open this spam mail, you will not be all the wiser. In fact the body of the mail will only point you towards the file attachment, which will look like a text document (.docm) or an image file (.jpg, .png, or .bmp). The sad news is that downloading and running this file will actually initiate this devastating attack. This is why it does not stop your files from being encrypted when you delete Ransomware from your system because by the time you notice its presence, it is already too late. But this fact should not stop you from acting. Leaving such a vicious program on your computer is out of the question if you ever want to use your PC. However, it is also vital that you become more cautious with your clicks when it comes to questionable e-mails and third-party advertisements as well.

How does Ransomware work?

After this ransomware is activated, it may complete its dark mission within one minute, which clearly does not give you enough time to react. It uses the widely used AES-256 algorithm to encrypt your files and appends a “.BLOQUEADO” extension to all the infected ones to leave its unique mark behind. It also creates a ransom note text file on your desktop called “-[AVISO-IMPORTANTE]-.txt,” which is displayed on your screen right after the damage is done. This is a Portuguese text, which lets us assume that this ransomware is mainly aimed at Brazil, Portugal, and any other Portuguese speaking countries.

This message informs you about the encryption and that your only chance to use your files again is to pay as much as R$ 1.500 ($445), which is 0.57 BTC that has to be transferred to a given Bitcoin wallet. After you are done with the money transfer, you are supposed to send an e-mail to and wait for their reply. The problem is that you may never hear of these cyber criminals again. Paying the ransom fee is always very risky. Since you could lose this money, we recommend that you remove Ransomware right now and only then can you copy your clean backup files back to your hard drive; if you have such a secured backup at all.

How do I delete Ransomware?

You may think that it is impossible to eliminate such a dangerous ransomware program, but it is not so. In fact, most of these infections are quite easy to remove since their mission is usually over with the encryption process; the mostly irreversible devastation is done. Since this malware does not lock your screen or block your major system executables either, you do not even need to restart your machine in Safe Mode. All you need to do is locate and delete the malicious executable file that you saved from the spam and ran to initiate this attack. If you wonder how you can do this, please use our guide below.
