Koti is what is identified by cyber security experts as a file-encrypting ransomware variant. This means that Koti applies encryption on the files of its victims to make them inaccessible.
The idea here basically revolves around a classic blackmail scheme, in which the victims’ files are held hostage in demand for a certain amount of money as ransom. Hence, the name of this malicious software category. The files are in essence rendered unreadable to any type of software, and therefore once they’ve been encrypted, unless you’re in possession of a special decryption key, you won’t be able to use them.
In turn, this decryption key is what the criminals behind the ransomware promise to send their victims after they’ve complied with the ransom demands. However, whether or not they will indeed send you a key once you’ve paid them is still questionable. It certainly wouldn’t be unprecedented for the hackers to vanish and you to never hear from them again. And in some instances, even if you are sent a key, there’s no telling whether or not it’s the correct one. Each instance of encryption requires its own unique key, so mixups can and do happen.
With this in mind, it’s a much better idea to try and resolve this problem using alternative measures. For one, removing Koti is of crucial importance – regardless whether you choose to deal with the hackers or not. This will ensure that at least no new files or potentially recovered ones get encrypted henceforth.
But after you have taken care of this, there are a number of ways in which you can try to get ahold of your locked data. We’ve put together a detailed removal guide just below this post to help you effectively eliminate this ransomware virus. And in the second part of the guide, we have also included these alternative file recovery methods that you can try.
The Koti virus
The Koti virus is a malicious piece of software that is capable of working under the radar of most antivirus programs. The encryption used by the Koti virus is essentially not harmful and therefore it usually won’t trigger your antivirus software.
Furthermore, some of the more advanced ransomware versions can actually even disable your antivirus program – just to make sure that it won’t interfere with its dirty business. This, as well as the complexity of the encryption itself, has greatly contributed to ransomware being considered the most dangerous type of malware out there. And with the rates at which ransomware is growing in popularity, it’s up to each and every user to do everything in their power to withstand it.
Namely, try avoiding such infections by staying away from their probable sources. These mainly include pirated software, spam messages and fake online ads. But even more importantly, keep backups of your valuable files on a separate drive or cloud.
The Koti file extension
The Koti file extension is visible at the end of each encrypted file name. The Koti file extension is pretty much what ensures that no software can recognize the data format.
|Danger Level||High (Ransomware is by far the worst threat you can encounter)|
|Symptoms||Very few and unnoticeable ones before the ransom notification comes up.|
|Distribution Method||From fake ads and fake system requests to spam emails and contagious web pages.|
|Data Recovery Tool||Currently Unavailable|
parasite may reinstall itself multiple times if you don't delete its core files. We recommend downloading SpyHunter to scan for malicious programs. This may save you hours and cut down your time to about 15 minutes.

Remove Koti Ransomware
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).
WARNING! READ CAREFULLY BEFORE PROCEEDING!
Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous.
Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:
This scanner is free and will always remain free for our website's users. You can find its full-page version at: https://howtoremove.guide/online-virus-scanner/
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.
Hold the Start Key and R – copy + paste the following and click OK:
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:
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:
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.
Type Regedit in the windows search field and press Enter. Once 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:
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!
