What antivirus programs call TeslaRVNG1.5 ransomware
Microsoft Defender reports TeslaRVNG1.5 ransomware as Program:Win32/Vigram.A.
In a Defender name, the part before the colon is the category, the part after it is the platform, and the part after the slash is the family Microsoft assigned. A suffix after ! is an internal Microsoft marker, not a different threat.
Generic labels such as Agent, GenericKD or Malware.AI only say that a file looks malicious, not what it does; our guide to antivirus detection names shows how to read them.

TeslaRVNG1.5 ransomware – a new file-locking-type computer infection from the Ouroboros family
TeslaRVNG1.5 ransomware is a malicious computer virus developed to extort money from its victims by encrypting their files and demanding a ransom to unlock them.
This cryptovirus derives from a relatively small ransomware family of Ouroboros, with members like Odveta virus, Zeropadypt NextGen virus, and others.
During the encryption, TeslaRVNG1.5 ransomware virus renames all data in a complex manner by prepending id .[tesla369@cock.li] and appending .teslarvng1.5 extension to all original filenames. In other words, if you had a file named a.pdf, it would now appear as id .[tesla369@cock.li].a.pdf.teslarvng1.5. Keep in mind that when files get locked, their contents aren't corrupted.
Following the file lockage, the file-locking parasite generates a ransom note, titled teslarvng1.5.hta, and leaves it on the desktop. When the file is opened, it appears as a pop-up window. With this note, cybercriminals want to pursue their victims to contact them by any of the two given emails - tesla369@cock.li, teslacrypt369@cyberfear.com.
Some of the previous versions from this lineage have already been decoded, so it's not the end of the world if you got your machine infected. We're happy you're here, as we strive to help our readers who are in a bit of a pickle. This article provides detailed instructions on how to get rid of TeslaRVNG1.5 virus both manually and automatically.
Ransom notes are created to scare and convince people that there are no other means to regain access to their files apart from paying the assailants. In many cases, that might be true, but under no circumstances do we agree with that. Actually, paying the ransom is the worse thing that an owner of an infected device could do because:
As soon as a user sees a ransom note or that their files are inaccessible, they must scan their devices with dependable anti-malware software, such as or , and get rid of any suspicious files. The same should be done with this article's culprit - perform a full system scan, and remove TeslaRVNG1.5 ransomware.
There's no point in reading the ransom note, as it is pretty much the same as all notes from all other cryptoviruses. The price isn't specified, nor is the preferred payment method (based on our research, it will most likely be Bitcoins). The whole note from the threat actors behind TeslaRVNG1.5 ransomware states:
We're going to reiterate one point - PLEASE DON'T CONTACT THE CRIMINALS OR PAY THE RANSOM. The only way to stop TeslaRVNG1.5 ransomware and other crypto-malware from spreading is by stoping the criminals from getting richer. If no one would pay the ransom, the criminals would be broke and wouldn't have the finances to develop new malware.
If you didn't have anti-malware software or the old one failed to stop the infection, get a trustworthy one, and eliminate the infection. In some cases, cryptoviruses can block this type of software from opening. Then you'll have to do a manual TeslaRVNG1.5 ransomware removal.
Please don't be scared, it's not rocket science. Just follow our step-by-step instructions at the end of this article, and you'll be done in five minutes. Once that's done, we highly advise to repair all corrupted system files with a powerful system tune-up tool like the .

Avoiding the most popular ransomware delivery techniques
There are various malware types, such as Trojans, worms, keyloggers, etc., and its payload files are delivered using different techniques.
Our cybersecurity experts report that the two most popular ways cybercriminals are spreading ransomware are through spam emails and file-sharing platforms.
Spam emails are created to spread various malware, and ransomware is one of them. Usually, the payload files are either in an email attachment or in a hyperlink that would lead to a malicious website.
Please don't open any emails or their contents that urge you to do something, like visit a certain site immediately because of some security issues, or download the attachment with important new details. Criminals use these techniques to trick people.
File-sharing platforms offer various copyrighted movies or pirated software for free. Cybercriminals exploit people's weakness for free stuff by camouflaging their creations as the most anticipated cracked games, free installers of expensive software, and alike. Refrain from using these sites altogether because any offered content might have a very unpleasant surprise hidden within.

due raas to avoid scam never pay anyone without testfile (even us),never pay outside of this 2 emails(even if you get replay of above emails from other email),incase of scam (witch wont happen 100% if you follow what said in this line) create a toptic at bleepingcomputer.com with proofs (email logs, and transaction proofs) ,admin will find you there and give your decryptor for free and ban the scammer
How to remove TeslaRVNG1.5 ransomware
Tools you'll need
All of these are free except where noted. Download them on a clean device if the infected PC is offline.
- A USB stick: to keep the ransom note, two or three encrypted files and screenshots off the infected PC.
- Microsoft Defender Offline: built into Windows 11 and Windows 10; scans before Windows starts, so running malware cannot hide.
- Microsoft Safety Scanner: a second, portable scanner with current signatures; each download works for 10 days.
- ID Ransomware: identifies the family from the note and one encrypted file and says whether a decryptor exists.
- No More Ransom: the free decryptors from police and security companies; check it again every few months.
- Fortect (optional): scans Windows for malware and repairs the system files and settings it damaged. The free scan is in the box above.
How to remove TeslaRVNG1.5 ransomware and get your files back
Work in this order.
Disconnecting comes first, removal comes before any restore, and nothing here asks you to contact the attackers.
Step 1: Disconnect the PC and unplug backup drives
TeslaRVNG1.5 ransomware encrypts everything it can reach, including drives and shares you connect later. Cut the network first: cable out, or Wi-Fi off from the taskbar.
Then unplug every USB stick and backup disk and pause cloud sync, so the encrypted versions do not replace your online copies. Do not reconnect any of them until the ransomware is removed from the Windows 11 or Windows 10 PC.
Windows 11: turn off Wi-Fi to take the PC offline. Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 2: Save the ransom note and confirm the family
Copy
the ransom noteand one or two files ending in.teslarvng1to a USB stick, and leave the originals where they are.From another device, upload the note and a sample file to ID Ransomware or No More Ransom's Crypto Sheriff, which name the family from the note, the extension and the file structure.
Write down the contact address and your personal ID from the note, because a decryptor or the police may ask for them.
Warning: Never contact the attackers from the infected Windows 11 or Windows 10 PC.

Step 3: Check for a free decryptor
For TeslaRVNG1.5 ransomware, no free decryptor is known (checked 7 October 2026). Search the family name in the No More Ransom decryption tools list and in the free decryptors of Emsisoft, Avast and Kaspersky, because new tools appear years after an attack.
Important: Keep the encrypted files even if nothing works today, and do not pay before every free option is ruled out: payment does not guarantee a working key.
Decryptors run on Windows 11 and Windows 10, but only after the ransomware itself is removed.

Step 4: Remove the ransomware before you restore or decrypt
Restoring or decrypting files while TeslaRVNG1.5 ransomware still runs lets it encrypt them again. Run a Full scan in Windows Security > Virus & threat protection > Scan options, then the Microsoft Defender Antivirus (offline scan).
If the ransomware blocks Windows Security, start Safe Mode with Networking and scan from there. Some families install a password stealer as well, so let both scans finish on Windows 11 or Windows 10.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 5: Look for shadow copies of the files
Open Command Prompt as administrator and run
vssadmin list shadows. If it lists copies dated before the attack, right-click a folder with encrypted files in File Explorer, choose Properties > Previous Versions, and open or restore a version from before that date.ShadowExplorer, a free tool, shows the same copies when the tab is empty or hidden. Most current families delete shadow copies, so an empty list is normal, but the check takes two minutes on Windows 11 or Windows 10.
Windows 11: vssadmin list shadows shows whether shadow copies exist. Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 6: Restore the files from a backup or recover deleted originals
Restore from an external backup, File History or OneDrive's version history, choosing a date before the attack. Connect the backup drive only after the scans are clean, or the ransomware encrypts it too.
If there is no backup, file recovery software can sometimes find the deleted originals, because some ransomware writes an encrypted copy and deletes the original file.
Stop writing to the drive and try recovery on Windows 11 or Windows 10 before new files overwrite the space.

Manual removal using Safe Mode
Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- 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.
- Select Safe Mode with Networking from the list.
Windows 10 / Windows 8
- Right-click on Start button and select Settings.
- Scroll down to pick Update & Security.
- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.
- Select Troubleshoot.
- Go to Advanced options.
- Select Startup Settings.
- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.
Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.
- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.
- Go back to the process, right-click and pick End Task.
- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.
Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.
- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
Downloads
Recycle Bin
Temporary files - Pick Clean up system files.
- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
%AppData%
%LocalAppData%
%ProgramData%
%WinDir%
After you are finished, reboot the PC in normal mode.

Tutorial for TeslaRVNG1.5 ransomware virus removal and system tune-up
To stay safe on the internet, people should acquire reliable anti-malware software such as or because cyber infections are hiding everywhere these days.
Professional AV tool will not only remove TeslaRVNG1.5 ransomware but prevent all kinds of malware and crapware from infecting devices if you keep them running from time to time.
The importance of a trustworthy anti-malware tool can be seen in a suspicious file analysis portal VirusTotal, which research shows that 34 out of 71 anti-virus engines caught the TeslaRVNG1.5 ransomware virus, thus preventing infection. Here's a couple of detection name variations:
If anti-malware tools are blocked by the cryptovirus, meaning they can't be opened, then reboot your computer and start it in Safe Mode with Networking. Then TeslaRVNG1.5 ransomware removal shouldn't be impeded. If you don't know how to launch that mode, refer to our free guide below.
Once the machine is virus-free, the next step is taking care of the system files and settings. This app will find all system irregularities and fix them with a push of a button so you could enjoy your device anew.

Report it and recover your files
Report it
Report the attack even if you do not expect the files back: insurers and banks ask for the report number, and police use the contacts in the note to link cases.
- United States
- FBI IC3 · FTC ReportFraud
- United Kingdom
- Report Fraud (formerly Action Fraud) · NCSC
- Australia
- ReportCyber (ASD)
- EU countries
- Europol: national reporting sites
Give the victim ID, the note and the date the files were encrypted. A business that holds personal data may also have to notify its data protection authority, in the EU within 72 hours.
Make the next attack harmless
TeslaRVNG1.5 ransomware could only hurt the files that had no second copy, and the signs (files that end in .teslarvng1 and no longer open) showed exactly which ones those were.
The 3-2-1 rule fixes that:
- three copies
- two media
- one disconnected
A practical version for a home PC: OneDrive or another cloud backup with version history, plus an external disk that you plug in once a week for File History and then unplug. Test a restore now and then by opening a few files from the backup on another device.
Details, schedules and what not to back up are in our 3-2-1 backup guide for Windows.
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.
One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.
However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable.
Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:
- power cuts
- Blue Screen of Death errors
- hardware failures
- crypto-malware attack
- even accidental deletion
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.
Questions about TeslaRVNG1.5 ransomware
Can a data-recovery company decrypt my files for a fee?
Only if a decryptor already exists or the company pays the attackers for you. Some "ransomware recovery" services advertise that they can decrypt families with no known flaw; in practice they negotiate with the attackers and add their own fee. Others use the same free tools listed on No More Ransom.
Before you hire anyone, ask in writing how they will recover the files, whether they will contact the attackers and what happens if they fail. A legitimate service answers clearly. If a free decryptor exists for your family, you can run it yourself.
How did TeslaRVNG1.5 ransomware get on my computer?
The way TeslaRVNG1.5 ransomware spreads has not been documented yet, so look at your own recent activity. On home PCs, ransomware most often comes with cracked programs, game cheats, key generators and fake updates, or with an e-mail attachment that was opened. On business networks, attackers usually log in through Remote Desktop with a stolen or guessed password.
Think back to what was downloaded or installed in the days before files that end in .teslarvng1 and no longer open, and check the Downloads folder and Installed apps sorted by date. Keep anything suspicious for your report, but do not run it again.
How do I open .teslarvng1 files?
You cannot open them by renaming or by choosing another program. The .teslarvng1 ending shows that TeslaRVNG1.5 ransomware encrypted the content, and only the matching key can reverse it. Renaming a file back to .docx or .jpg changes nothing except the icon, and it can confuse a future decryptor, so leave the names as they are.
To get the content back, use a backup, an unencrypted copy elsewhere, or a decryptor listed on No More Ransom if one exists for TeslaRVNG1.5 ransomware. Store the encrypted files on an external disk until then.
Is there a free TeslaRVNG1.5 ransomware decryptor?
We last checked on 7 October 2026, and for TeslaRVNG1.5 ransomware no free decryptor is known. We check No More Ransom, which collects free tools from police and security companies, and the decryptor pages of the major antivirus vendors. A working decryptor exists only when the encryption has a flaw or the keys were leaked or seized.
Ignore sites and videos that offer a "TeslaRVNG1.5 ransomware decryptor" for download or for a fee: these are usually scams or malware. Real decryptors are free and come from known security companies or law enforcement. Keep the encrypted files in case a tool appears later.
Should I pay the ransom?
We advise against it, and so do the FBI, Europol and national cyber agencies. Payment does not guarantee a working tool: some attackers never reply, some tools damage files, and some variants have no decryptor at all. Paying also funds further attacks and can make you a target again.
Before considering payment, try every recovery option in this guide and report the attack. Companies must involve their legal adviser and insurer, because payments to sanctioned groups can be illegal. If files are truly irreplaceable, store the encrypted copies and wait; decryptors sometimes appear later.
Did TeslaRVNG1.5 ransomware steal my files or passwords?
We do not know yet. Nothing published so far shows data theft by TeslaRVNG1.5 ransomware, but the only confirmed sign is files that end in .teslarvng1 and no longer open, which says nothing about what happened before. Many current ransomware attacks copy files or run a password stealer first, so it is wise to act as if they did.
From a clean device, change the passwords that were saved in the browsers on this PC, starting with e-mail and banking, sign out of all sessions and turn on two-step verification. Watch bank statements and account activity for the next few weeks.
Is TeslaRVNG1.5 ransomware the same as other ransomware with a similar name?
Not necessarily. Ransomware names come from the file extension, the note or a word in the code, so unrelated families often end up with similar names, and one family can appear under several names. The difference matters: a decryptor or advice for one family does not fit another and can damage files.
Compare the ending added to your files and the exact name of the note with the summary table at the top of this guide, then upload the note and one encrypted file to ID Ransomware from a clean device. If the result names another family, follow the guide for that family instead.
Can I just remove .teslarvng1 from the file names?
You can try it on a copy, but for real ransomware it will not help. The .teslarvng1 extension is only a label; the file content has been scrambled with a key the attackers hold.
If a renamed copy opens normally, the malware only renamed files, which happens with some fake ransomware, and you can rename the rest back. If it does not open, leave the files as they are. Renaming encrypted files can confuse a decryptor later, so always work on copies.
Is Program:Win32/Vigram.A a false positive?
Sometimes. Names ending in !ml or describing behaviour are generated by machine learning and occasionally flag cracked tools, game mods or small unsigned utilities. A false positive is likely only when the file is a program you installed from its official developer, it is signed by that developer and other scanners do not flag it.
Files from cracks, cheats, fake updates or unknown downloads are rarely false positives, whatever the detection name. If you are sure the file is genuine, you can report it to Microsoft as a false positive; never add an exclusion for Program:Win32/Vigram.A just to make the alert stop.
Will Fortect remove TeslaRVNG1.5 ransomware?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For TeslaRVNG1.5 ransomware, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
