Good apps are never free, to begin with.

Even if free, many features will be disabled.

Your BitDefender did not manage to block the ransomware before it spread? Ransomware won't simply attack your computer if you didn't do anything hanky pranky.

How ransomware spread and attack their victim?
1. Download and install illegal/pirated software/games
2. Browsing to video streaming websites (porn or non-porn)
3. Visiting to porn or illegal online gambling websites
4. Malicious email attachment or links thru email
5. Someone purposely inject the malware onto USB storage and share it to you
6. Someone on the same network got infected by the ransomware and it spread across network thru share folder

Basically, DJVU ransomware is not that new anymore and those file which encrypted by ransomware cannot be recover. Just forget it unless those data encrypted worth over 6 digits. There are many case that corporate paid to the ransomware creator but it didn't manage to decrypt back all files 100%.

Honestly I dont really use those software that shows up first in results like easeus, wondershare, etc...

because they just want to sell you their software

they generate many articles with a template like "How to fix [problem]"

the first few methods are hard and confusing, so you give up on those and download their software instead.

Uninstall 360 Total Security. This China AV always secretly download and install something on your computer. My friend install it on his laptop before and after that found out got many tiny application installed and running on his laptop without his knowledge. I also installed it on my dad old laptop and it also install some plug-in and additional software onto the laptop. I working as IT in international school before, I got few student come to my office seek for help because the laptop becoming slower and I found out all of them running with this 360 Total Security. I help them remove it and clear the registry with CCleaner. After reboot, everything run smoother.

First of all, please upload the ransom note and the encrypted file here:
https://id-ransomware.malwarehunterteam.com/

This will determine the type of ransomware you've been infected with icon_idea.gif

From the thread title, you said that it is a STOP (DJVU) ransomware - this is a very common form of ransomware, spread through pirated/cracked software, especially popular software such as Windows/Office/Adobe software suites/AutoCAD:

https://www.bleepingcomputer.com/news/secur...adware-bundles/


Note that ransomware attacks can be very devastating not just due to loss of important data, in many cases ransomware can bundle additional malicious software such as infostealers (information stealers) that can steal passwords and credentials of your online accounts such as email and online banking accounts which can be used to take over or compromise your online accounts for more nefarious purposes icon_idea.gif
https://www.bleepingcomputer.com/news/secur...e-cryptominers/

You should change your passwords for all your online accounts on an uninfected machine, and enable 2 step verification (also known as 2 factor authentication, 2FA) if the online accounts supports it. Enabling 2 factor authentication can significantly improve your security of your online accounts by requiring an additional authentication method, such as codes generated from a mobile app. This will prevent cybercriminals from accessing your account even if your password has been compromised in some ways or another icon_idea.gif

You should also never try to pay the ransom, as cybercriminals are not obliged to give you the data back even if the ransom are paid (in fact this will further incentivizes the ransomware author more), see here:
https://www.bleepingcomputer.com/forums/t/4...-2#entry5109879

It is also possible that the encrypted data may not be recoverable and in this case occurs, your data should be considered permanently lost and you should restore them from a backup icon_idea.gif
Warning: you should only restore your data if your machine has been thoroughly disinfected, otherwise the ransomware can encrypt your backups


Now, you should try using ShadowExplorer and try to recover your files through Shadow Copy (a Windows feature that takes snapshots of files which can be used for file recovery). However this may not work as many ransomware often deletes the snapshots to prevent any possible restoration of data:
https://www.bleepingcomputer.com/download/shadowexplorer/

There is a forum thread dedicated to assist DJVU ransomware victims, so it might be worth asking here instead:
https://www.bleepingcomputer.com/forums/t/6...-topic/page-753

File: D:\Ipah\New folder (2)\Untitled-2.psb.ifla
Error: No key for New Variant online ID: 3WyrirwICWLhJjYqDA60XthiKhEfVXdLRhiFzHeZ
Notice: this ID appears to be an online ID, decryption is impossible


From the forum thread:
QUOTE
Decryption of new STOP (Djvu) variants is impossible IF infected by an ONLINE KEY without paying the criminals for that victim’s specific private key...these keys are unique for each victim and randomly generated in a secure manner
Unless the cybercriminal responsible for the ransomware has been arrested by the police with the decryption key being released to the public, there's basically nothing you can do to get your data back. Make this a hard lesson that:
1. Never download pirated software as many ransomware tends to be bundled with cracked software
2. Never visit shady websites or websites offering links to pirated content
3. Use an adblocker; while the use of adblocker is controversial as this can deprive the website owner of ad revenue, however an adblocker will be useful against malicious advertising (malvertising) and sometimes it is considered as a important security feature for modern web browsers icon_idea.gif

There's nothing you can do for unknown ransomware encryption but wait. If you're lucky, you will get a decryption key in the future but don't get your hopes up
Most decryption key is only released when the culprit is caught
But right now there's nothing you can do but move on from this and learn the lesson of not storing your important data in only 1 place
If you're unwilling to pay for cloud storage, store your important data in multiple storage. At least in 2 places

Run secure erase on your SSD/HDD then do a clean installation of Windows
*
Even cloud storage may not help in this case due to ransomware can encrypt the cloud folder of your PC, which will be synced to your account unless your cloud storage supports some form of versioning icon_idea.gif

Not long ago, a netizen come to programming board and ask for help, though I was skeptical of his request, might he use the program as ransomware to encrypt target's data?
