How to delete SIFRELI virus

About this malware

SIFRELI virus will lock your files and request that you make a payment in exchange for their decryptor. Ransomware is regarded as a high-level infection, which might cause highly serious consequences. Specific file types will be locked soon after the ransomware launches. Photos, videos and documents are among the most targeted files because of how valuable to people they are. Files cannot be opened so easily, they will need to be decrypted using a specialized key, which is in the hands of the people responsible for your file encryption. Occasionally, malicious software analysts are able to crack the ransomware and develop a free decryption program. If backup isn’t available and you have no other way to restore files, your best option might be to wait for that free decryption tool.

You will find a ransom note either on the desktop or in folders that contain files which have been encrypted. The note should explain what happened to your files and how much you need to pay to get a decryptor. Buying the decryption program isn’t exactly a good idea due to a couple of factors. Hackers taking your money while not helping you with file recovery isn’t a surprising scenario. They might guarantee you a decryptor but who will guarantee that promise will be kept. Perhaps, investing into backup would be better. In case you have made copies of your files, simply terminate SIFRELI virus.

Fake updates and spam emails were likely used to spread the ransomware. The reason we say you most probably got it through those methods is because they are the most popular among cyber crooks.

How does ransomware spread

Spam emails and bogus updates are possibly how you got ransomware, even though other spread methods also exist. If you recall opening a weird email attachment, you have to be more cautious in the future. Don’t blindly open every single attachment you get, you first have to ensure it’s safe. In a lot of such emails, senders use known company names as it would lower people’ guard. You might get an email with the sender claiming to be from Amazon, alerting you that your account has been displaying signs of weird behavior. Whoever the sender claims to be, you should be able to easily check that. Just locate the real email addresses the company uses and see if your sender’s email address is in the list. Moreover, use a malware scanner to check the file before opening it.

If you are sure spam email is not responsible, fake software updates may also be responsible. The fake software updates may be encountered when visiting web pages with dubious reputation. It’s also not uncommon for those false update notifications to appear through advertisements or banners. Nevertheless, because those alerts and advertisements appear very false, people familiar with how updates work will simply ignore them. Do not download anything from ads, because you are you are endangering your computer for no reason. When a program of yours requires to be updated, either the application in question will notify you, or it will update itself without your interference.

What does this malware do

Your files have been locked, as you’ve probably noticed by now. File encryption might not be necessarily noticeable, and would have began quickly after you opened the infected file. You’ll see that a file extension has been attached to all affected files. There is no use in attempting to open affected files since a powerful encryption algorithm was used for their encryption. You’ll then see a ransom notification, where hackers will say that your files have been locked, and how you may get them back. All ransom notes appear essentially identical, they initially explain that your files have been encrypted, request for that you pay and then threaten to eliminate files permanently if you don’t pay. While hackers may be right when they say that it isn’t possible to unlock files without their assistance, paying the ransom isn’t something many specialists will recommend. Keep in mind that you would be relying on the people responsible for your file locking to recover them. Furthermore, if hackers know that you paid once, they could make you a victim again.

There is a likelihood that you could’ve stored at least some of your files somewhere, so try to recall if that could be the case. Our advice would be to backup all of your locked files, for when or if researchers specializing in malicious software develop a free decryptor. It is very critical that you uninstall SIFRELI virus from your computer as quickly as possible, whatever the case may be.

While we hope your file recovery is a success, we also would like this to be a lesson to you about how important it is that you back up your files frequently. If you don’t make backups, this situation might reoccur. Several backup options are available, and they’re quite worth the investment if you don’t want to lose your files.
