Oopu
Oopu is a money-extortion computer virus that makes its victims’ files inaccessible until a ransom payment is released. Malware programs such as Oopu are referred to as Ransomware and are known for employing file-encryption to lock the data of their victims.
The threat of getting attacked by a Ransomware cryptovirus such as Oopu is ever-present nowadays, and if you indeed get such a malicious program in your computer, the consequences can be particularly unpleasant if you keep sensitive files that are important to you on the infected machine. If you keep regular backups of your most important files, a Ransomware attack would be much less problematic, but the truth is that most computer users don’t really have exhaustive backups, and once a Ransomware attacks their computer, all of their data gets locked up via encryption and there’s no way to access it without the decryption key. The hackers behind Oopu, .Paas, Nusm, Ehiz count on that, because their goal is to get you to “purchase” said key from them. If you refuse to send them your money, they will never provide you with the key to recover your data. The problem is that they may not give you that key even if you do pay them. After all, those people are criminals, and you can’t really trust any promise they’ve made. Of course, there’s also the problem of the ransom sum being quite significant in most of the cases – we are talking about four-digit numbers, and it is understandable that most users would probably not have this kind of money readily available to them for a ransom payment. These and many other factors are what makes Ransomware such a problematic category of computer threats. Our job here is to try to help you get out of this sticky situation with as little negative consequences as possible.
The Oopu virus
Oopu is a virus for Windows which encrypts all user data and then tells the user that the only way to decrypt the files is through the payment of a ransom. The Oopu virus displays a pop-up note with payment instructions after the encryption.
Obviously, paying the money demanded by the hackers isn’t the wisest decision in this situation, but then again what is? Well, for starters, it is advisable to remove the virus at once – having malware in your system is never a good thing. Removing the Ransomware isn’t going to release your data, but it will prevent further encryption of new files you create on your computer, which is a good start. Also, if you want to try some alternative data recovery solutions the presence of the virus on your machine would thwart them as any piece of data you may manage to restore would probably get locked up once again by the Ransomware that’s still in the computer. Also, make sure that you DO NOT connect any other devices to your machine until you make sure that the computer is clean from the Ransomware. Otherwise, you may get all data in those devices encrypted as well, which could destroy your best chance of recovering your data.
The Oopu file extension
The Oopu file extension is a series of symbols that replace the normal extensions of your data files. This Oopu file extension is partially what makes the encrypted files inaccessible through regular means since no program recognizes it until the decryption key is applied.
To remove this virus, our suggestion for you is to refer to the guide you’ll see below. The instructions and the professional removal tool shared in the said guide will allow you to eliminate the sneaky Ransomware, which will make your computer safe again. And after the cryptovirus is taken care of, you would be free to try the recovery recommendations from the second part of the guide manual. How effective those recommendations would be for your case is up to you to find out – sadly, we cannot promise you that your files will get fully restored, but you should still try all alternatives available to you as that may allow you to bring your data back without being forced to pay a ransom.

Remove Oopu Ransomware
The first thing that you need to do is some preparation for the smooth removal of the ransomware. Start with:
- Bookmarking this page (You will need it for later reference.)
- Rebooting the computer in Safe Mode (This will make it easier to detect the threat and remove it.)
WARNING! READ CAREFULLY BEFORE PROCEEDING!

With the computer booted in Safe mode, launch the Windows Task Manager (CTRL + SHIFT + ESC) and select the Processes Tab. In the list of running processes, look for those that could be linked to Oopu. Possible signs could be a higher CPU or RAM usage, unusual image or user name, etc. However, many ransomware threats may use a fake name of a legitimate process in order to delude the users. That’s why be very careful and once you detect a questionable process, right-click it and select the Open File Location option.
When you get to the file location, drag the found files in the free online virus scanner that is available here:
Run the scan and, if the results show that they are malicious, go back to the Processes tab, end the related process, and then delete its files and folders from the file location.
In this step, we will explain to you how to check if your computer has been hacked. For that, press the Start and R keys from the keyboard. A Run box should pop-up immediately on your screen. Copy the following in the Run box:
notepad %windir%/system32/Drivers/etc/hosts
After that, click OK and this will open the Hosts file of your computer on the screen. The Hosts files can give you a lot of useful information but you need to head to the bottom where it is written Localhost and check there for any suspicious IP addresses.
In case you see a number of IPs below Localhost (just as it is shown on the image above) this could be a sign that the computer is hacked. Of course, before you jump to any conclusions, we advise you to leave us a message in the comments below this post if you detect any questionable IP addresses and we will tell you if they belong to a virus creator or not.
After that, go to the System Configuration app (you can open it quickly by typing msconfig in the windows search field and hitting enter). and select the Startup tab:
Your job here is to find entries that are linked to Oopu and are set to launch with the startup of the system and to remove their checkmark from the checkbox. Be very careful here, as in this list there will be important startup processes, as well as entries that might be fake or with “Unknown” Manufacturer. Make sure that you uncheck everything that seems questionable and leave only the legitimate processes checked in.

Another very important thing that will help you to remove Oopu from your computer is to detect and delete its entries from the Registry. For that, you need to first open the Registry Editor app (by typing Regedit in the windows search field and pressing the Enter key) and then use the CTRL and F key combination to open a Find dialog box in the Editor.
In this Find dialog, you need to type the exact name of the threat, which in your case is Oopu, and then click on the Find Next button on the right. Let the Find function search and then delete any entries that are found for that name. Do the search as many times as required until no more entries are found with that name.
Important! Be very careful with this step as any deletions in the Registry that are not linked to the ransomware may lead to serious system corruption.
After that, in your Windows Search Filed, carefully type each of the five lines below one after the other:
- %AppData%
- %LocalAppData%
- %ProgramData%
- %WinDir%
- %Temp%
Then, when you get to each of these folders, check if anything new has recently been added to them. The content from the Temp folder should be removed completely.

How to Decrypt Oopu files
The Oopu file decryption is a matter of another guide that is specially created and regularly updated. Once you remove Oopu from your computer, you can go to this guide and try to recover some of your files with the help of its instructions.
