Ooss

Ooss is a representative of the Ransomware category that can encrypt different user files. The main aim of Ooss is to make victims pay for their encrypted files to be released.

Ooss

The Ooss Virus will show you this message in a _readme.txt file.

On this page, you will find a removal guide will help you to get rid of Ooss if this is what has infected your system. Furthermore, the removal of ransomware like this one is very important since if the virus is running on the machine it will possibly encrypt any new files you want to access or create. Moreover, the ransomware may encrypt even more information, including the data stored on devices that get connected to the compromised computer, such as your smartphone and tablet. If you manage to successfully remove Ooss, however, you will have the chance to safely connect file backup sources and restore your information from external devices, cloud storage or other data storage devices.

The Ooss virus

The Ooss virus is a cryptovirus that specializes in encrypting user data and preventing the owners from accessing it. The criminals behind the Ooss virus typically demand a ransom from the victims and insist on a quick money transfer in order to provide a decryption key.

When the file-encryption process ends, the victims are typically informed that they can get back their encrypted information only if they pay a ransom to a given cryptocurrency account. If the money is transferred, a special decryption key should be given to them. But it’s obviously not a very good idea to trust these promises made by anonymous cyber criminals. The reason is, you can’t tell if the hackers behind the ransomware really want to provide you with a decryption key or if they’re just lying to you. In the second scenario, you will send a substantial amount of money to them without any guarantees about the future of your files and your computer. In addition, the demanded ransom amount may be quite high, which is another reason why it is preferable to search for solutions to remove the infection and restore your data without paying a penny to the crooks behind Ooss.

The Ooss file encryption

The Ooss file encryption is a method that helps criminals to block access to user data and keep it hostage for a ransom. The Ooss file encryption is a stealthy process that runs without visible symptoms in most cases.

The problem with the Ooss encryption is that even after the ransomware has been removed, nothing can guarantee that the encrypted files will be restored to their previous state. The corresponding decryption key is, as described above, the normal way to unlock the encrypted pieces of data. But it may not be possible to always get the key from the hackers, even if you pay the ransom. Therefore, to restore your information, you may need to find other methods. In the second part of our removal guide, you will find some suggestions on that. Keep in mind, though that, in general, it is very difficult to deal with a threat of this kind, particularly when it’s new such as Ooss, Rooe and Alka. Some of your files may still be hard to get back, but if some backups are left on other machines, on an external drive or on cloud storage, this is the time to use them. Just make sure you remove the ransomware first, to prevent it from encrypting your backups.

Ooss Ransomware Removal


Step1

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous.

ClamAV
AVG AV

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.

Step3

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:

msconfig_opt

Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.

Step4

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

Type each of the following in the Windows Search Field:

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

Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
