How .v315 virus, v315 ransomware behaves

From our report of Nov 2020 · not reviewed since

v315 ransomware - new Jigsaw family member that encrypts users data

v315 ransomware is a new member of the JigSaw virus family that shows an informative ransom note after encryption.

Jigsaw family ransomware was first detected in March of 2016. This is a cryptoworm which, after gaining entry to a targeted computer system, encrypts all of its non-system files. All personal data is appended with .v315 extension and becomes inaccessible. Once the files are locked, a ransom demanding pop-up window appears with a lot of instructions.

Since the discovery of the Jigsaw family ransomware, a decryption tool has been available to the public for free by Micheal Gillespie. But since this software was last updated on 05/18/20 01:24:58 PM EDT, and the v315 virus is brand new, this software might not do the trick.

Whether to use it or not is up to the victim. You should remove the virus and clear the system - prepare the computer for file recovery. Especially, when decryption is not guaranteed.

Unlike most ransomware blackmailing notes, the particular message from v315 virus creators is long, informative, and consists of 5 parts. In the first part of the ransom note, the cybercriminals explain that the victims' files were encrypted and the only way to regain access to the locked data is by paying them 70 USD in Bitcoins.

The perpetrators also urge the victims not to delete or disable the v315 ransomware virus, otherwise, the perps will delete 1000 files from the infected device. To avoid punishment, users should comply with all the rules given in the second part of the ransom note:

  • do not turn off or restart the computer
  • do not run any anti-virus program
  • do not connect USB devices
  • so on (see the whole list of rules below this article)

The third part is an explanation of what Bitcoin is, who created this cryptocurrency, how it works, and so on. Forth part is unlike anything seen before. There's a timer running backward. When time runs out - one encrypted file is deleted from the computer.

In the last part of the ransom demand, the victims can find a Bitcoin wallet address ([payment address omitted]) into which they should forward 70 USD worth of the cryptocurrency to receive a v315 file virus decryption tool.

To evade dealings with cybercriminals, computer users should always use powerful anti-malware software. Trustworthy apps like and should be trusted to remove v315 ransomware. These programs can detect incoming malware and prevent devices from infections.

Once the user computer is virus-free, experts advise, using a system tune-up tool or an optimizer like to automatically scan and fix what the v315 ransomware did to computer system files and prevent the device from displaying any anomalous performance, such as crashing, overheating, etc.

Below is text extracted from all parts of the ransom note (4th part is not included, as it consists of a timer that's running out):

Ways cybercriminals infect computer users' devices

People usually don't think about consequences when pressing the mouse button on some innocent-looking ad or email attachment.

Well, in this day and age, they should, because malware is hidden everywhere on the internet, and it's waiting for oblivious soon to be a victim to click on it.

Infectious email attachments, bogus software installers, or illegal activation toolkits on torrent websites, these are just a few sure ways to contaminate a computer. Always be sure that the content that's about to be opened is genuine, legitimate.

Never open phony looking hyperlinks in emails received from unknown senders. Please don't open any email attachments without scanning them first. To be safe while browsing, use trustworthy anti-malware software to have your back.

The .v315 virus, v315 ransomware note

Text of the ransom note

Welcome. If you are reading this you are probably wondering what happened to your computer, so let me explain. All your private .png .doc .txt... files have been encrypted and there is no way to get them back other than by paying the relatively small price of 70 USD. Also remember that any attempt to disable or delete the virus will be punished with the removal of 1000 encrypted files from your device.

Of course, if you want to avoid punished, I would advise you to enter the RULES tab which will appear after finishing the dialogue

Remember also that after a limited time, a specific number of files will be deleted automatically. If you want to see how much time you have (The number of files deleted will gradually increase over time),enter the tab that will appear after completing the dialogue.

You can rest assured that the program does not spread to other devices, it only attacks those who launch the fake application.

Summing up, remember to not to turn off or restart your computer, your files can be decrypted by our program, the maximum number of deleted files can be 1000, payment can only be in bitcoins and remember to load the RULES tab, that's all about it.

So now let's start the real destruction.

How to remove .v315 virus, v315 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 .v315 virus, v315 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.

  1. Step 1: Disconnect the PC and unplug backup drives

    .v315 virus, v315 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.

  2. Step 2: Save the ransom note and confirm the family

    Copy the ransom note and one or two files ending in .v315 to 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.

  3. Step 3: Check for a free decryptor

    For .v315 virus, v315 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.

  4. Step 4: Remove the ransomware before you restore or decrypt

    Restoring or decrypting files while .v315 virus, v315 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 Security Scan options with Microsoft Defender Antivirus offline scan selected
    Windows 11: Windows Security > Virus & threat protection > Scan options.

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

  5. 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.

    Command Prompt running vssadmin list shadows
    Windows 11: vssadmin list shadows shows whether shadow copies exist.

  6. 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.

Guidelines to remove .v315 file virus and restore system files

Having your computer infected can ruin anyone's day.

Especially when you lose important files. The first and foremost thing to do is to eliminate the contamination because the longer the malware stays in a computer, the more damage it could do. To automatically remove v315 ransomware, use or ; these apps will locate the ransomware and all its files and delete them. Furthermore, your device will be protected from future attacks.

Viruses from the Jigsaw ransomware family are known to modify infected computer system files so that they could operate more efficiently. v315 ransomware virus isn't an exception, hence after removal of the malware, use a reliable system tweak tool .

It will instantly find and restore any changes that have been made to your system settings and its files so that you could enjoy your device anew. Remember that it is safe to recover files only after the proper v315 ransomware removal process.

[GI=method-1]Try rebooting the machine in Safe Mode with Networking, so you can run the AV tool and remove v315 ransomware

[GI=method-2]System Restore is the feature that recovers machine to a previous state and helps get rid of v315 ransomware

Windows Previous Versions - individual file repair solution

Windows Previous Versions works when you enable System Restore in the first place

ShadowExplorer - solution for encoded files when data backups are lacking

Shadow Volume Copies should be untouched before you can use ShadowExplorer as a solution

v315 ransomware cannot be decrypted yet

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

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.

Protect the files you restore

Restore only after the scans are clean and the PC no longer shows files that end in .v315 and no longer open; otherwise the restored copies can be damaged again.

Then build a backup that survives the next infection:

  • one copy in the cloud with version history
  • one on an external drive that is disconnected between backups
  • the working copy on the PC

Version history matters because a backup that syncs damaged files overwrites the good ones.

How to do this with the tools built into Windows: the 3-2-1 backup rule on Windows.

Protect your privacy - employ a VPN

There are several ways how to make your online time more private - you can access an incognito tab.

However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise.

Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers - human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence.

In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. is one of the leading file recovery solutions you can find on the market - it is likely to restore even lost emails or data located on an external device.

Questions about .v315 virus, v315 ransomware

Is there a decryptor for .v315 files?

That depends on the family behind the .v315 extension, which this guide cannot confirm yet from the reports alone. Check No More Ransom and ID Ransomware with your ransom note and one encrypted file; they list families with free tools.

If none exists today, keep the encrypted files and a copy of the note on a separate drive, because decryptors are sometimes published months later after flaws are found or servers are seized. Never buy a decryptor from a website that is not the security company that made it.

How do I open .v315 files?

You cannot open them by renaming or by choosing another program. The .v315 ending shows that .v315 virus, v315 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 .v315 virus, v315 ransomware. Store the encrypted files on an external disk until then.

Did .v315 virus, v315 ransomware steal my files or passwords?

We do not know yet. Nothing published so far shows data theft by .v315 virus, v315 ransomware, but the only confirmed sign is files that end in .v315 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.

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.

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 .v315 virus, v315 ransomware get on my computer?

The way .v315 virus, v315 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 .v315 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.

Is .v315 virus, v315 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.

What does the ransom note tell me about the ransomware?

Quite a lot. The file name the ransom note, the wording, the contact addresses and the format of the personal ID are typical for each family. Uploading the note together with one encrypted file to ID Ransomware or No More Ransom's Crypto Sheriff usually names the family within seconds.

That name decides your options: some families have free decryptors, some can be partially recovered, and some cannot be decrypted at all. The note's claims about stolen data should be taken seriously but not at face value.

Will .v315 spread to my other drives?

It can. Ransomware encrypts every drive and network share it can reach while it runs, so external disks, USB sticks and shared folders connected during the attack may also have files ending in .v315. Disconnect everything now, then check each device from a clean computer.

Do not plug a backup drive into the infected PC until the ransomware has been removed with an offline scan. Cloud folders such as OneDrive sync the encrypted versions, but they keep earlier versions you can usually restore.

Will Fortect remove .v315 virus, v315 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 .v315 virus, v315 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.
