anybody knows about ransomware the filesystem got encrypted and should I pay 200$ for unlocking?

No, don't support malware.

Wipe your harddisc, change to some linux based OS and restore your data from the backup.
If you need Windows stuff, use it in a VM and make a backup of the VM every now and then.

Oh, you have no backup? I'm sorry, but then you will surely have one from now on.
Try to google if there is a decryption tool for your kind of ransomware. If so and it works, you're really lucky. If not you dearly paid with your data, and hopefully learned your lessons.

@ddephor Wipe the disk would be the best solution to get rid of the ransomware - but unfortunately database archive from 2007 is encrypted to, so the payment was done and everything is decrypted - File Version may safe enough to get an earlier version of the files - but it was turned off, now its ok thanks anyway

After reading this, I feel as if though my eyes have gotten cancer.

@SCamp yes and I feel 200$ dollar less....

Kaspersky seemed to have found a number of keys for ransomware , you should have checked them out

@TheAnimatrix I did it with all of them and even with AVG 30 exe files - no success

https://noransom.kaspersky.com try this, do not pay them

@muli353 try darrkfall link or if you can download software to your computer, download appcheck. Ransomware decrypter, works awesomely well for selected ransomware, updates every day

@daarkfall I tried already all of them no success

@muli353 are you sure they're really 'encrypted'? Most ransomwares move and rename files to weird names instead of really encrypting them.. Encrypting 100GB worth of data does take a lot of time...

@Russian I tried it with a simple text file, I changed the extension back to .txt, the content was not plain text but with different symbols and numbers - it took around 15 min to decrypt all the HDD (80 GB)

O.o oh man wtf

Offline backups, end of story.

@LMtx Yeah a good lesson for the other time...

@muli353 we learn all the time man

@muli353
How do you even get yourself a randomware? It should be nearly impossible for any person that knows how to use a computer to get one... I'd say be more careful with the porn/shitty cracks gotten from google you download

@eeeddr Lol, it wasn't my pc but one of my clients - they don't care about viruses and so on... but even me Im not using an antivirus

@muli353
And you were the one who paid for it? That makes no sense...

@eeeddr Yeah it's a dummy situation, actually the client paid, but he kept saying that our software caused that virus... lol
