It can be really daunting when you get infected with the likes of Fenrir Ransomware, but the most important thing is to not panic. If you panic, you will probably do exactly what the people behind this infection want: You will give your money away. It is for the best to spend your money on a licensed antispyware tool rather than giving it away for something you may never get. Please remove Fenrir Ransomware from your system at once, and then look for ways to restore your encrypted files. Please note that you should be ready to lose your files for good if there is no way to retrieve the healthy copies.
You probably got infected with this ransomware program when you opened something that looked like a PDF document. The installer file for this infection masquerades as an Adobe Reader file, and it usually comes in spam email attachments. The email that carries the installer may look like an invoice from an online store or some financial report. If you have not been expecting anything of the kind, you should refrain from opening the file. Also, if you think that you must open the file no matter what, you can always scan it with a computer security tool of your choice.
On the other hand, if the infection is already there in your system, there is not much you can do just watch how it takes over your computer. Upon the infection, Fenrir Ransomware will establish connection with its command and control center because it needs to report the infection to its HQ. The DNS request the program sends out leads to an IP address that is registered in the Netherlands, but that does not mean that the program has been created by Dutch hackers. As you can probably tell, there are no national borders in the cyber world.
The program will also encrypt your files, adding a unique extension to the filenames. This extension is based on your Hardware ID, so each infected computer will end up with a different extension. Needless to say, you will not be able to open your files once the encryption is complete. Aside from that, you will also see your desktop background changed, but the ransom note will be displayed separately in another window. The ransom note is pretty direct and the text says this:
ALL YOUR FILES HAVE BEEN LOCKED
(Q) HOW TO RECOVER MY FILES?
(A) Sending to me the amount of 150$ dollars in bitcoin for my bitcoin ID after the payment has been made send the transaction ID and your personal ID to my email and then i will send you the unlocker.
Then the note provides you with the bitcoin address and the email address you have to use to contact these criminals. However, please be aware that paying the ransom may not solve your problems. You would only encourage these criminals to continue their malicious activities.
Remove Fenrir Ransomware immediately, and then look for ways to get your files back. Perhaps you keep a system back in the form of an external hard disk? Maybe you have a lot of your files saved on your mobile device? Perhaps the most recent documents were saved in your inbox? Whichever it might be please consider all the options before giving up on your data.
