Oovb is a Ransomware virus that targets web users by encrypting their computers’ information and asking for a ransom to decrypt it. Oovb can infect a computer when users interact with malicious messages, infected torrents, bogus software, fake pop-up messages, or Trojan horses.

The Oovb virus will create a .txt file with this message inside.

Sadly, a growing number of web users have been encountering Ransomware infections like Oovb, .Wbxd and .Coos and have failed to find a way to get rid of them. We have received many requests from users to help them tackle threat like these and remove them from their computers. That’s why, in this article, we came up with instructions on how to remove Oovb from your device. In the paragraphs that follow, you can learn more about this threat as well as the Ransomware infections in general, their specifics, their delivery methods and the preventive measures that you can take to keep them away from your machine in the future.

The Oovb virus

The Oovb virus is an online threat that targets certain files stored on a particular computer and renders them inaccessible by applying a strong encryption algorithm to them. The encryption placed by the Oovb virus cannot be reverted unless the victims purchase and apply a special decryption key form the hackers behind the infection.

Unfortunately, the encrypted files remain unavailable until a ransom is paid for the decryption key. This is a very lucrative type of online extortion, where user information is held hostage and the victims are threatened to never access it unless they agree to pay the required ransom. The main problem is that many people panic and agree to pay the money that the hackers behind the ransomware ask for their data without any guarantee that they will actually recover the encrypted information.

The Ransomware shows a ransom note on the screen of the infected computer after the files of the victim are encrypted. This message normally provides instructions on how to transfer a fixed amount of money to a cryptowallet. The criminals that control the ransomware typically threaten that if the payment is not made within a given time frame, the ransom amount may double or the decryption key for the encrypted files may be deleted, leaving them inaccessible forever.

The Oovb file decryption

The Oovb file decryption is a process that enables the Oovb ransomware victims to retrieve their encoded information. The decryption of the Oovb files needs to be carried out with a special decryption key which is exchanged for a fixed amount of money.

When deadlines are pushing you and your information is encrypted, you will naturally be very frustrated to find a quick solution to the problem with Oovb. This type of emotional assault that the hackers rely on, however, aims to make the victims take quick and impulsive decisions and pay as soon as possible without looking for a legitimate solution.

But paying the required ransom doesn’t just help the cyber criminals boost their Ransomware’s success and profits – it can also be really bad for you. Think about what if the decryption key isn’t submitted or if the complex encryption algorithm simply isn’t reversed successfully? Not only will you spend a substantial amount of money but your information will remain inaccessible for an indefinite period of time. We, therefore, suggest that you first explore some other solutions and find out how to remove the infection in the most effective manner.

Remove Oovb Ransomware


The first step is to find and stop the process(s) of the Ransomware to prevent further encryption of your files and to make the virus removal easier. You can see the currently running processes on your computer from the Processes tab of the Task Manager. To go there, press the Ctrl + Shift + Del key combination from the keyboard and select Processes. There, look for items with suspicious or unfamiliar names that are using up an unusually big portion of your computer’s resources (RAM and CPU). It can help you single out the Ransomware process if you quit all currently open programs so that their processes would quit as well and there will be less items to search through to in the Task Manager. If you think that you may have figured out which process is coming from Oovb, type its name in Google or in another reputable search engine and press Enter to see what results come up. In some cases, a legitimate system process could look like it is malicious so it is important to rule out this possibility before you proceed to deal with the process in question.


If your online search confirms that the process isn’t from your OS, proceed to right-click on it and then select the Open file location button. Use the scanner we have provided you with below to scan each of the files from that folder or use your own antivirus or anti-malware program if you have one on your PC for the scan. In fact, it’s best if you use both options for maximum certainty.

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    If even a single file is flagged as malware, go back to the questionable process in the Task Manager, right-click on it, select End Process Tree and once this is done, delete the whole folder that is its file location. If one or more files from that folder can’t be deleted and this prevents you from deleting the folder itself, delete whatever you can from inside the folder and go to the next step. Once the rest of this removal guide is finished, be sure to come back to the file location folder and try to delete it again – by that time, you deleting that folder should prove to be no problem.

    The next thing you ought to do is boot your computer into Safe Mode to keep any processes related to the Ransomware that you may have missed from being run automatically. On the following link, you can find instructions on how start your PC in Safe Mode.

    Press Winkey + R from your keyboard, type msconfig, and press the Enter key. Once the System Configuration window opens, select Startup from the tabs and then proceed to uncheck every item from the list of startup items that has Unknown listed under the Manufacturer column as well as all items that seemunfamiliar and potentially related to Oovb.

    Finally, select the OK button to save the changes and apply them and then move on to the next step.


    hosts_opt (1)

    You must place this line “notepad %windir%/system32/Drivers/etc/hosts” (without the quote marks) in the Start Menu search bar and press Enter. Look at the bottom of the text from the notepad file named Hosts that shows up on your screen and if there are any strange IP addresses (or any other lines of text) written right below “Localhost“, copy them and send then to us using the comments section on the current page. We will have a look at those IP and if we determine that they are likely related to Oovb, we will tell you to delete them from Hosts in our reply to your comment.

    After you delete the IPs (if that’s what we told you to do), Save the Hosts file and proceed to Step 5.


    Important! In this step, you will have to locate items related to Oovb in the Registry of your PC and delete them. It is very important to only delete items from the Registry if you are certain that they are from the virus or else you may risk making your system unstable by deleting the wrong thing. Therefore, remember that the comments section below this article is open to you if you want to ask us about a Registry item that you suspect of being linked to Oovb but are not totally sure.

    Press Winkey + R again, type in regedit in the Run search field, and hit Enter to start the Registry Editor. If the OS demands that you give your Admin permission to the Editor to make changes to the computer, click on Yes to proceed.

    When the Registry Editor appears on your screen, press Ctrl + F, type the name of the virus, and press Enter or click on Find Next. This will search the Registry for items that contain Oovb in their names and show you the first such item. If anything gets found, click on it, press Del, and then click on Yes to delete that item. The proceed to perform the search again, delete the next found item, and repeat the process until nothing is left with the name Oovb in the Registry.

    Following this, navigate to the next directories from the Registry and look in them for folders/items that have unusual names that stand out from the rest. Malware programs and other unwanted software tend to add folders with long names that consist of randomized characters on those Registry locations so it shouldn’t be too difficult to spot such folders. Still, if you are in doubt, remember to consult us first and only then proceed with the deletion if we confirm that the item(s) you aren’t sure about is to be deleted.

    • HKEY_CURRENT_USER > Software
    • HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Run
    • HKEY_CURRENT_USER > Software > Microsoft > Internet Explorer > Main


    For the final step of this guide, you must copy each of the next folder shortcuts in the Start Menu field and press Enter to access the folders they correspond to.

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Once each folder opens, sort the items in it by order of date and proceed to delete everything created since the virus has infected your computer. In the folder named Temp, simply delete all files that are stored there.

    Lastly, we once again remind you to delete the File Location of the malware process alongside all files that are still stored in it (Step 1) if you haven’t been able to do this earlier.

    How to Decrypt Oovb files

    Deleting the Oovb virus is important to secure your computer and to prevent further data encryption but it won’t automatically recover your files. To restore your data without paying the ransom, you will have to perform some additional actions that we have explained in a separate How to Decrypt Ransomware guide that you can access by clicking on the provided link. Go to this guide and try the methods listed there to hopefully recover the files that Oovb has managed to lock up. Just make sure that before you go there, you have made sure that the virus has been fully removed from your PC or else anything you may manage to recover could get encrypted all over again if Oovb is still present in the system. The free malware scanner available on our site can help you determine if there are any traces from the Ransomware left on your computer by allowing you to scan any files that you deem suspicious.

    Final Notes

    The guide we’ve provided you with on this page should allow most users to fully eradicate the Oovb threat. However, if you suspect that the virus is still on your computer, it would be a great idea to use the advanced malware-removal tool that you will find linked on the current page as it can both quickly find and take care of any remnants of the Oovb virus as well as provide your system with powerful protection against malware in the future.
