Ogre ransomware virus. How to remove? (Uninstall guide)

removal by Gabriel E. Hall - - | Type: Ransomware

Authors of the Ogre ransomware might be preparing to launch a new cyber attack

Ogre is an in-dev ransomware virus that asks only 20 euros for data recovery. Nevertheless, the ransom is little; dealing with cyber criminals and following their orders is never recommended. This crypto malware uses a strong encryption algorithm to lock various files on the targeted computer. It appends .ogre file extension and runs a program window with a ransom-demanding message. Authors of the Ogre ransomware in a poor English language informs that malware encrypted critical files. In order to scare people even more, hackers claim that turning off the computer may lead to the damaged device. However, no one should believe in these words. It’s just a psychological terror to convince people into paying the ransom. However, if malware attacks your device, you employ Reimage or another reputable malware removal program and run a full system scan. It will help to remove Ogre from the PC and recover your files from backups safely.

Ransom note by Ogre ransomware virus

The virus arrives on the system as an obfuscated OgreRSMWRE.exe file. Once executed, Ogre might initiate changes in Windows OS, create Registry entries, and install numerous malicious files to the computer. However, the main task of the ransomware is data encryption. It aims at the most popular file types such as various picture, text, audio or video files, databases, documents, etc. However, it stays away from the crucial system files that are necessary to run the computer. Compared to other file-encrypting viruses, Ogre ransomware asks a small amount of money for data recovery. Indeed, it might be the reason why people might be willing to risk and transfer the money. Losing 20 euros may not be the biggest problem. Using a decryption software may lead to another malware attack, or you might be threatened into paying even more money. Thus, dealing with cyber criminals should never be under consideration.[1] It’s better to focus on Ogre removal and look up for other ways to recover your files.

Ransomware distribution methods and ways to avoid the attack

At the moment of writing, Ogre hasn’t started spreading widely. However, malicious spam email campaigns might soon start distributing this cyber infection. It’s the most popular distribution method. People receive an email with obfuscated malware payload, and if they are tricked to click the attached file or the included link, malware enters the system. Thus, before opening files received from unknown senders, make sure that it’s actually safe to open.[2] If an email looks suspicious, delete it immediately. Ogre ransomware virus might also be relying on malvertising and deliver malicious ads on various websites. Keep in mind that malware-laden ads might also show up on legitimate sites as well. The virus might also be presented as a useful program or crucial update in various online sources. Thus, you should choose credible sources for software downloads and install updates only from official publisher’s site.

Ogre removal should be performed using professional malware removal program

Ogre belongs to the group of dangerous cyber infections. Thus, you should not try to remove it manually. It might have installed numerous malicious files, started dangerous processes and made complex system modifications. Thus, to terminate all these components entirely and safely, you have to employ a professional malware removal program. For Ogre removal we firmly recommend choosing one of these tools: Reimage, Malwarebytes or Plumbytes Anti-MalwareNorton Internet Security. We can assure that these three programs are credible and can complete this task efficiently. However, malware may prevent from installing the program or scanning the system, but you can disable the virus by following the instructions below.
