PayDOS virus Removal Guide

What is PayDOS ransomware virus?

PayDOS ransomware looks retro – can it actually encrypt your files?

PayDOS virus is an in-development ransomware and how we see it now is likely to change in the nearest future. The malicious program reaches the target computer in the form of a .exe file, which saves a batch file into %Temp% folder. If you do not know what a batch file means, you should know that it is a file that contains instructions that the computer system needs to carry out. This particular batch file commands to search for specific file extensions and rename (not encrypt!) them. However, the virus does not rename the file entirely – it only changes one letter of the file extension. Of course, files remain recognizable, and what is best, just like its subsequent version Serpent virus, it does not damage them, which means victims can fully recover all of them. You can find detailed instructions how to do it below PayDOS removal guidelines presented at the end of this post.

After “encrypting” victim’s files, PayDOS ransomware launches Administrator: PayDOS program, which displays the ransom note starting with lines “I am so sorry you can see me. If you can, I have bad news. It seems all your data has been encrypted and there is nothing that you can do about this.” The malefactor asks the victim to pay 0.33 BTC (approximately $234) if he/she wants to get data back, but we are about to kill criminals’ dreams now. You can fix your files without paying the ransom by entering AES1014DW256 password. After doing this, remove PayDOS virus entirely using the FortectIntego software.

Ransomware distribution tricks

Ransomware authors are hideous criminals who know what is the main spot of human beings. It’s curiosity; people tend to click on content that they clearly have no relation with and even when they realize that such click can get their fingers burnt. Criminals craft up emails that seem legitimate at first sight. You can see examples of typical titles that cyber criminals use for their malicious spam campaigns:

  1. Your Amazon Order No.#[random digits] has been dispatched;
  2. Invoice No. [random numbers];
  3. Your Account PayPal Has Been Limited;
  4. Medical Test Results.

Beware of hideous letters – they seem to be legitimate at first sight. Before opening an email, check what is the email address of the sender. Clearly, a sender who sends out “official” letters from an email address like is not an employee of a legitimate company like PayPal or Amazon. Therefore, you should never open attachments that come with such letters!

Guide which is presented above is supposed to help you remove PayDOS from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by PayDOS, you can use several methods to restore them:

Restore files without paying

There is no need to fix each distorted filename manually. Just enter AES1014DW256 code into the malicious program and hit Enter. This should fix all of your files immediately. Do not forget to scan the system with a proper security software to erase all malicious files and programs (PayDOS virus could be bundled with additional malware at the time it has been installed, so you must find and remove these extra components, too!)

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
