How to remove CRYPTER v2.40 ransomware

CRYPTER v2.40 ransomware can permanently damage users' personal files including photos, and documents

CRYPTER v2.40 ransomware is a dangerous program that can cause irreparable damage to victims, their files, and the machine. When it infiltrates the system, it starts using complicated encryption algorithms^[1] to lock users' personal files. This includes photos, videos, documents, etc.

When the encryption process is done, the affected files are appended with the .crypter extension. For example, if a file was previously named picture.jpg, now it would look like this – picture.jpg.crypter. The icons also turn to white pages so thumbnails are no more available.

Users may also notice that they cannot open their files or use them in any way. That is where the ransom note comes in. A pop-up window appears on the screen informing users about what has happened to their files and what needs to be done to get them back. Cybercriminals ask to be paid in return for a decryption key.

The ransom note

The full pop-up ransom note from CRYPTER v2.40 ransomware creators reads as follows:

CRYPTER v2.40

CRYPTER

YOUR FILES HAVE BEEN ENCRYPTED!

Ooooop!! If you are seeing this message, it means you weren't careful about what you clicked on! Tisk, Tisk!!

If you are sure that you have been careful – well, thats even worse – that means someone else wasn't, and that this virus has now started to spread from computer to computer on your local network!!
I hope you see this and mitigate the spread before its too late…..
Well, anyway….
Each computer affected has a different key, meaning you'll need to pay for them all seperatly.

Thanks now, Have a nice day.

BITCOIN FEE: 0.08134

The threat actors explain to victims that their files have been encrypted because they were probably not careful enough on the Internet. They also ask for 0.08134 BTC (which is about $2580 at the time of writing) in return for a decryption key. Cybercriminals use scare tactics to make victims act as quickly as possible without thinking clearly.

Cryptocurrencies^[2] are chosen as a form of payment because they are anonymous. It is also impossible to get a refund. Once you send a cryptocurrency transaction to someone, it is irreversible. We strongly advise against paying the ransomware developers because they cannot be trusted.

Many previous ransomware victims have come forward and reported that they never heard back from them after they sent the money. Even though there is almost no other way to get your files back, you might also get scammed if you take the risk. In this guide, you will find a third-party recovery solution that can help in some cases.

Distribution methods

Although it is unknown how specifically CRYPTER v2.40 ransomware is spread, there are some general tactics that cybercriminals use. Most often, people get infected with ransomware when installing “cracked” software^[3] from torrent sites, and peer-to-peer file-sharing platforms. These websites are unregulated, so they are the perfect breeding ground for all kinds of malware.

It is best to use only official web stores and developer sites whenever you want to install software. Apps that get listed on digital marketplaces have to go through an extensive review process. You should also always do your research – read the reviews, look at the ratings, and the number of users.

Another possibility is that the malicious file appeared in your system through email. Crooks can disguise the emails using social engineering^[4] methods and include infected attachments. That is why it is best not to open any email attachments that you are not sure of. Even if the attachment came from someone you know, it is best to double-check with them through another platform. 

You might also not realize how important it is to keep your operating system and software updated. Hackers can use software vulnerabilities to deliver their malicious programs. Software developers regularly release security patches which should be installed as soon as possible if you want to keep your system safe.^[5]

Remove the intruder from your machine

The first thing you have to do is remove the malicious files that are executing the tasks. If you try to recover the files without eliminating the cause, it can encrypt your files again and result in more damage. Removing the virus yourself should not be an option unless you have experience in this and know what you are doing. Use anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes to scan your system.

This security software should find all the related files and entries and remove them automatically for you. Automatic removal is the best option because there is less risk of leaving some of the files on our system. Another thing to note is the malicious program could be preventing you from using the antivirus software, so check that first. If you are unable to do it, proceed with accessing Safe Mode on Windows:

Windows 7 / Vista / XP

1. Click Start > Shutdown > Restart > OK.
2. When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
3. Select Safe Mode with Networking from the list.

Windows 10 / Windows 8

1. Right-click on Start button and select Settings.
   
2. Scroll down to pick Update & Security.
3. On the left side of the window, pick Recovery.
4. Now scroll down to find Advanced Startup section.
5. Click Restart now.
6. Select Troubleshoot.
7. Go to Advanced options.
8. Select Startup Settings.
9. Click Restart.
10. Press 5 or click 5) Enable Safe Mode with Networking.

Data recovery options

Only hackers hold the decryption key, which can unlock your files, so if you did not back them up previously, you possibly lost your files forever. You can try using data recovery software, but third-party programs cannot always decrypt the files. We suggest at least trying it because it cannot hurt.

Important – only do this if you have already removed CRYPTER v2.40 ransomware

Before proceeding, you must copy the corrupted files and place them in a USB flash drive or another external storage. In case something happens, you will at least still have the encrypted files. 

1. Download Data Recovery Pro.
2. Double-click the installer to launch it.
   
3. Follow on-screen instructions to install the software.
4. As soon as you press Finish, you can use the app.
5. Select Everything or pick individual folders where you want the files to be recovered from.
6. Press Next.
7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.
8. Press Scan and wait till it is complete.
9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
10. Press Recover to retrieve your files.

Run a maintenance tool to fix system issues

Performance, stability, and usability issues, to the point where a full Windows reinstall is required, are expected after malware infection. These types of infections can alter the Windows registry database, damage vital bootup and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not able to repair it. 

There are tools created just for this purpose. FortectIntego can fix a lot of the damage caused by an infection like this. Blue Screen errors,^[6] freezes, registry errors, damaged DLLs, etc., can make your computer completely unusable. By using this maintenance tool, you could try fixing the damaged system and avoid reinstallation.

• Download the application by clicking on the link above
• Click on the ReimageRepair.exe
  
  
• If User Account Control (UAC) shows up, select Yes
• Press Install and wait till the program finishes the installation process
• The analysis of your machine will begin immediately
• Once complete, check the results – they will be listed in the Summary
• You can now click on each of the issues and fix them manually
• If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.
