Oct virus Removal Guide
What is Oct ransomware?
Oct ransomware – a cryptovirus that not only encrypts personal data on targeted computers but steals some of it too
Oct ransomware - a virus that shows a scary message with money demands.
Oct ransomware is a cryptovirus designed to encrypt personal user data on a targeted computer and demand a ransom for the promised decryption tool. Unlike other file-locking parasites like Nobu or Weui, the culprit of this article steals some of the personal files for blackmailing purposes before locking them.
As soon as the virus accesses a computer system, it locates the most frequently used files and downloads them onto a secret hacker server. Only when this is done, the encryption process begins, which locks all personal (or business) files, such as documents, images, audio/video files, databases, archives, etc., by appending a .oct extension to all of them.
When encryption is completed, .oct file virus generates ransom notes, named READ_ME.txt, and spreads them all over the infected computer so that the victim could find it easily. The developers of this cryptovirus would like to be contacted only through a given email – email@example.com.
|Appended file extension||.oct extension is appended to all non-system files|
|Additional info||Hackers state that they've downloaded some data, and if the victims won't pay the ransom, they will make the stolen files available to the public|
|Criminal contact firstname.lastname@example.org|
|Virus removal||Malware should be dealt with swiftly with the help of reliable anti-malware software, so remove Oct ransomware using a powerful AV tool|
|System fix||Cryptoviruses might do extensive damage to system files and settings, so it's highly recommended to perform system clean-up with the ReimageIntego tool|
The whole ransom note (displayed below this paragraph) is written in poor English, it has many grammatical mistakes that in some cases make it hard to understand the message. Firstly, the hackers explain to their victims that all personal files have been encrypted, and a part of them was stolen but will be deleted after the ransom payment is completed.
The second part of the note consist of instruction. Victims should contact the developers of Oct ransomware virus by emailing them at email@example.com. The cybercriminals would explain the rest of the process after contact is made.
The last part is quite hard to understand, but one thing is clear – if the victims won't pay an unspecified amount of money (most likely in cryptocurrency Bitcoins) to the creators of Oct ransomware, they will expose all allegedly stolen information to the public.
As always we advise not to contact the criminals. There are cases where even after meeting the demands of the hackers, the victims didn't receive any decryption tools, or even worse – got scammed for even more money. Users should focus on Oct ransomware removal and overall system health.
Although victims could try to remove Oct ransomware manually, we recommend leaving the dirty work to professional anti-malware software like SpyHunter 5Combo Cleaner or Malwarebytes to do it automatically. A reliable anti-virus app is a must these days because the internet is crawling with different kinds of malware.

Tutorial on how to remove Oct ransomware from affected devices
As we've stated before – dealing with criminals might only bring more harm to you and your computer. That's why we recommend getting rid of the cryptovirus as soon as it's detected or at the first sight of the ransom notes. Manual Oct ransomware removal is possible, but it could take a lot of time and be a hard nut to crack for inexperienced users. Perform a full system scan with reliable anti-malware software like SpyHunter 5Combo Cleaner or Malwarebytes to do it automatically.
Malware tends to mess up the system registry and other core places, so a system tune-up is in order.

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
