PETYAX Ransomware (.petyax Files) How to Remove?

The Petyax virus falls under the ransomware type of infection. Harmful software of such sort encrypts all user’s data on the computer (images, text files, excel tables, music, videos, etc) and adds its own extension to every file, leaving the note.html files in every directory containing encrypted files.

What is known about the Petyax virus?

Petyax will add its extra .petyax extension to every file’s name. For example, a file entitled “photo.jpg” will be turned into “photo.jpg.petyax”. In the same manner, the Excel sheet with the name “table.xlsx” will be renamed to “table.xlsx.petyax”, and so on.

In each directory that contains the encrypted files, a note.html text document will be created. It is a ransom money note. Therein you can find information on the ways of contacting the racketeers and some other information. The ransom note usually contains a description of how to buy the decryption tool from the tamperers. You can obtain this decrypting software after contacting [email protected] by email. That is basically the scheme of the malefaction.

How did my machine catch Petyax ransomware?

There are many possible ways of ransomware injection.

There are currently three most popular methods for criminals to have ransomware settled in your system. These are email spam, Trojan infiltration and peer-to-peer file transfer.

• Another option for ransom hunters is a Trojan virus model. A Trojan is a program that infiltrates into your machine pretending to be something different. Imagine, you download an installer of some program you need or an update for some software. But what is unboxed turns out to be a harmful agent that encodes your data. As the installation wizard can have any title and any icon, you’d better be sure that you can trust the resource of the files you’re downloading. The optimal thing is to trust the software companies’ official websites.
• As for the peer-to-peer file transfer protocols like torrents or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. So you’d better be using trustworthy resources. Also, it is a good idea to scan the directory containing the downloaded files with the anti-malware utility as soon as the downloading is finished.

How do I get rid of ransomware?

It is important to note that besides encrypting your data, the Petyax virus will most likely deploy Vidar Stealer on your PC to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can extract your logins and passwords from your browser’s auto-filling cardfile.

How do I avert ransomware infection?

Petyax ransomware has no superpower, neither does any similar malware.

You can defend your computer from its attack taking several easy steps:

• Ignore any emails from unknown mailboxes with unknown addresses, or with content that has likely no connection to something you are expecting (how can you win in a money prize draw without even taking part in it?). In case the email subject is more or less something you are waiting for, scrutinize all elements of the dubious email with caution. A hoax letter will always have mistakes.
• Avoid using cracked or unknown software. Trojan viruses are often distributed as a part of cracked products, most likely under the guise of “patch” to prevent the license check. Understandably, dubious programs are difficult to tell from trustworthy software, because trojans may also have the functionality you need. Try searching for information about this software product on the anti-malware message boards, but the best solution is not to use such programs at all.

FAQ

🤔 How can I open “.petyax” files?Are the “.petyax” files accessible?

Negative. That is why ransomware is so frustrating. Until you decode the “.petyax” files you will not be able to access them.

🤔 The encrypted files are very important to me. How can I decrypt them quickly?

Hopefully, you have made a copy of those important files. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. The rest of the methods require patience.

🤔 What should I do if the Petyax ransomware has blocked my computer and I can’t get the activation code.

🤔 What can I do right now?

Some of the blocked files can be found elsewhere.

• If you exchanged your important files via email, you could still download them from your online mail server.
• You might have shared photographs or videos with your friends or family members. Just ask them to give those pictures back to you.
• If you have initially got any of your files from the Internet, you can try downloading them again.
• Your messengers, social networks pages, and cloud disks might have all those files as well.
• It might be that you still have the needed files on your old PC, a laptop, mobile, memory stick, etc.

HINT: You can use data recovery utilities¹ to retrieve your lost information since ransomware blocks the copies of your files, removing the authentic ones. In the video below, you can see how to recover your files with PhotoRec, but be advised: you can do it only after you eradicate the virus with an anti-malware program.
