File Extension error

Hi, I am a windows 10 user and I am lately facing a problem with my few pdf files which seems to have automatically changed its extensions to ".NJFITAVTX" in addition to .pdf

For Ex: "xxyyzz.pdf" got changed to "xxyyzz.pdf.NJFITAVTX"

I am unable to open those pdf files and I also found a NJFITAVTX-DECRYPT.txt file in that same folder

I tried renaming the file to .pdf yet the file says corrupted while opening.

So, could I use read my pdf normally again by removing this extension and yet read the file at the same time

Couldn''t find any similar problems anywhere on the net, so please let me know if there is a solution to this

Thanks

This is a typical case of ransomware. That's malware that decrypts your files and then asks money to decrypt it again.

The best way to handle this is to reset Windows 10 and restore all corrupted data from your backup. After that, be more careful with what you download and install than you were when you installed this malware.

What antivirus are you using?

Oh, I am currently using McAfee as antivirus
So, I can't recover those files?

Unlikely, unless you know the name of the ransomware. What's the content of that .txt file (open it in Notepad)?

That's clear, isn't it?

You can try the free decryptor from Bitdefender, found by https://www.google.com/search?q=gandcrap+decrypt
It's best to make an image backup first, to go back to if the decryptor makes a still greater mess of the situation.
