.PrOtOnIs Ransomware File

PrOtOnIs can take your files hostage!

Not having access to your valuable work-related or personal files, documents, archives, images, audios, videos and other data due to a sudden file encryption is surely a very unpleasant experience. What is even more frustrating is the fact that some anonymous hackers are actually blackmailing you to pay a ransom if you ever want to access them again. Ransomware threats like PrOtOnIs Ransomware are created to operate exactly like that – they secretly infect people’s computers, scan their hard-drives and apply a very complex encryption algorithm to files that belong to certain commonly used data formats in order to provide the hackers with leverage over the user for the blackmailing that is to follow. This is a criminal blackmailing scheme which the hackers use to make quick money by blocking their victims’ access to their most important data files.

Various social engineering techniques are used to mask a Ransomware infection and to trick people into getting their machines infected. Usually, the crooks spread their harmful programs via massive spam campaigns where they camouflage the infection as an attachment, a link, an interesting offer, PDF files, different installation packages and .exe files, infected ads or misleading web pages. In many cases, PrOtOnIs Ransomware might not come alone and instead get loaded into the system via a Trojan horse or an exploit kit which finds system vulnerabilities and exploits them in order to insert the infection. Such advanced methods of contamination are extremely difficult to detect and prevent on time and often only a reliable antivirus software may be able to deal with them effectively. Unfortunately, visible symptoms are rarely observed and the victims typically come to know about the Ransomware after it has already encrypted their data. PrOtOnIs usually generates a scary ransom-demanding message, which prompts its victims to make a payment within a given deadline. The criminals who are in control of the infection normally promise to send a special decryption key to those who pay the required ransom and claim that this key would bring their encrypted files back to normal.

How to Decrypt PrOtOnIs files

We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here.

Paying the ransom may actually be a very bad idea!

The hackers who create Ransomware viruses and control them never hesitate to threaten their victims and manipulate them in various ways. Some of the tactics they use to convince the targeted users to pay without giving them time to research for possible alternatives include short deadlines, fake notices from the authorities, stating that you have to pay a fine, and even open threats about deleting the encrypted files, destroying their decryption key or increasing the ransom amount if their demands are not fulfilled in time. Many other shady tactics might be used for the same purpose but what is really important is that one should not get panicked and let fear and frustration dictate their decisions. Paying the criminals can never truly guarantee a successful recovery from the Ransomware’s attack and may often result in money and data loss. In fact, if we have to be honest, a complete recovery from Ransomware could not be guaranteed with any known method which is why preventing future infections is really important.

What the security experts advise in case of an infection with PrOtOnIs is to stay calm and carefully research possible alternatives to the ransom payment. To get back your files, you can use external backup copies (if you have any), free decryption tools or file-recovery instructions (we have included such instructions below). The first step towards any attempts of data restoration, however, should always be to remove the active malware from your PC. The alternatives for that may include contacting a professional for assistance, purchasing a specialized Ransomware-removal software or using a manual Removal Guide such as the one on this page.
