How to Remove ._NEMTY_BTKid9H file virus
If you have working backups of your encrypted files or you aren’t going to attempt as well as recover lost files, then scan your PC with one or several antivirus and anti-malware programs or reinstall the OS altogether.
Back up Your Encrypted Files
It is always recommended to create a copy of the encrypted files and put it away. That might assist you if free ransomware decryptor get available in the future, or either if you want to pay and get the decryptor but something goes wrong and files get poorly damaged in the process of decryption. Skip to the explanation
Use File Recovery Tools to Recover Files
Nevertheless, if you want to attempt all possible ways for recovering encrypted files, including data recovery tools, then I suggest you use the given tools first and scan with anti-malware later.
Recover Encrypted Files From Shadow Copies.
The simple way to access Shadow Volume Copies is using a free utility named Shadow Explorer. Just download the latest version and install it (or download the portable version).
- Launch Shadow Explorer.
- On the top left part of the window you can select a disk (C:\, D:\, etc.) and a date when a snapshot of files was taken.
- To recover a file/folder right-click on it and choose Export…
- Select where do you want to save the files.
Remove ._NEMTY_BTKid9H file virus
Now that you have your recovered or still encrypted files on an external device, it is time to scan your computer with Anti-virus and anti-malware software or, better yet, reinstall the OS, to fully get rid of possible ransomware traces. Remember to also scan your removable device before storing files back on your computer!
Manual Steps – Boot Into Safe Mode:
Windows Xp, Windows Vista, Windows 7:
- Restart the computer.
- Once appears a boot screen tap F8 key repeatedly until a list of options appears.
- Use arrow keys to choose Safe Mode with Networking.
- Press Enter.
Windows 8, Windows 8.1, Windows 10:
- Hold down Windows key and hit X key.
- Select Shut down or sign out.
- Press Shift key and click on Restart.
- When asked to choose an option, click on Advanced options => Startup Settings.
- Click Restart in the bottom right corner.
- After Windows restarts and shows you a list of options, press F5 to choose Enable Safe Mode with Networking.
How to Recover Files Encrypted by ._NEMTY_BTKid9H file virus
If you need to recover files encrypted by ransomware either you can try to decrypt them or use methods of file recovery.
Ways to decrypt the files:
- Contact the ransomware developers, pay the ransom as well as possibly get the decryptor from them. This is not absolute: they might not send you the decryptor at all, or might be badly done and fail to decrypt your files.
- Wait for security experts to find few vulnerability in the ransomware which would allow you to decrypt files without paying. This turn of events is important but not very probable: out of thousands of known ransomware variants only dozens were found to be decryptable for free. You can visit NoMoreRansom site from time to time to view if free decryptor for GandCrab exists.
- Use paid services for decryption. For instance, antivirus vendor Dr. Web offers its own decryption services. They are free for users of Dr.Web Security Space as well as some other Dr. Web’s products either Dr. Web have been installed or running at the time of encryption (know more). For users of other antiviruses the decryption, if it is deemed possible, will price approx €150. Identical to Dr. Web’s statistics, the chances of them being able to restore files is about 10%.
Other ways to recover encrypted files:
- Restore from backup. If you make daily backups to a separate device as well as check from time to time in working order and files can be successfully restored – well, you possibly won’t have any issues getting back your files. Just scan your computer with a couple of Antivirus and anti-malware programs or reinstall OS and then restore from backup.
- Recover some files from cloud storage (DropBox, Google Drive, OneDrive, etc.) if you have one connected. Even if encrypted files were previously synced to the cloud, a lot of cloud services keep old versions of altered files for some time (usually 30 days).
- Recover Shadow Volume Copies of your files if those are available – ransomware usually tries to delete them too. VSS (Volume Shadow Copy Service) is a Windows technology which time to time generates snapshots of your files and allows you to roll back changes made on those files or recover deleted files. VSS is activated together with System Restore: it’s turned on by default on Windows Xp to Windows 8 and disabled by default on Windows 10.
- Use file recovery software. This probably won’t work for Solid State Drives (SSD – it is a newer, faster and more expensive type of data-storage devices) but is worth a try if you store your data on a Hard Disc Drive (HDD – older and more common as of yet storage device). When you delete a file from your computer ystem– and I mean permanently delete: use Shift + Del or empty the Recycle Bin – on SSD it gets wiped from the drive right away. On HDD however, it rather gets marked as deleted, and the space it occupies on a hard drive – as available for writing, but the data is still there and usually recoverable by special software. However, the more you use the computer, especially if you do something that writes new data on the hard drive, the more chance that your deleted file gets overwritten and will be gone for good. However, in this guide we ‘ll try to recover lost files (as you remember, ransomware creates an encrypted copy of a file and replaces the original file) without installing anything on a disk. Just know that it still might not be enough to completely recover your files – after all, when ransomware creates encrypted files it writes new information on a disk, possibly on top of files it just deleted. This actually depends on how much free space is there on your hard drive: the more free space, the less chance that new data will overwrite the old data.
Afterward, we need to
- stop ransomware, encrypting files that we recover, if malware is still alive;
- try not to overwrite files deleted by ransomware.
The optimum way to do it is disconnect your hard drive and connect it to other computer. it will enable to browse all your folders, scan them with antivirus programs, use file recovery software or restore data from Shadow Volume Copies. By the way, it is better to download all tools you’ll need beforehand and disconnect the computer from the Internet before connecting the infected hard drive, just to be safe.
Disadvantages of this method:
- This might void your warranty.
- It’s harder to do with laptops, and you’ll need a special case (disk enclosure) to put a hard drive in before connecting it to another machine.
- It is possible to sync the other computer if you open a file from the malfunctioned drive before scanning the drive with Antiviruses and deleting all found malware; or if all Antivirus fail to find and remove the malware.
Other, simple way is to load into Safe Mode and do all file recovery measures from there. Therefore, that will mean using the hard drive as well as possibly overwriting few data. In this case it’s advisable to use just a portable versions of recovery software (the ones that don’t require installation), download them onto an external device, and save any recovered files onto an external device too (external hard drive, thumb drive, CD, DVD, etc.).
