Is this a dangerous malware

.666 Files Ransomware is a type of malware that locks files and might lead to serious harm. Ransomware is believed to be a serious infection, which may lead to highly serious consequences. Certain file types will be encrypted soon after the ransomware is launched. It’s likely that all of your photos, videos and documents were locked because you’re likely to hold those files as very valuable. A special key is needed to decrypt the files but unfortunately, it’s in the possession of criminals who contaminated your PC in the first place. There is some good news as the ransomware is occasionally cracked by people specializing in malicious software, and a free decryption tool could become available. In case, you haven’t made backup, waiting for the mentioned free decryption program is your best choice.

Once the encryption process has been completed, if you look on your desktop or in folders containing encrypted files, you ought to find a ransom note. The ransomware authors/distributors will explain in the note that files have been encrypted and the sole way of getting them back is to purchase a decryptor. Paying for a decryption tool is not advised due to a couple of factors. We wouldn’t be shocked if the cyber crooks just take your money. That money will also go towards developing more malicious software. A wiser investment would be backup. If you have made backup, simply eliminate .666 Files Ransomware and proceed to file recovery.

You opened a dangerous email or downloaded some kind of fake update. Those methods are very common among crooks.

How is ransomware spread

You probably got the ransomware via spam email or bogus program updates. If you opened an attachment that came attached to a spam email, you have to be more cautious. Before you open the attached file, you have to carefully check the email. Senders of dangerous spam oftentimes pretend to be from legitimate companies to create trust and make users lower their guard. For example, they might pretend to be Amazon and say that the added file is a receipt for a recent purchase. If the sender is actually who they say they are, checking that will not be hard. Look at the sender’s email address, and no matter how legitimate it may appear initially, check that it really is used by the company they say to be from. Moreover, use a malware scanner to check the file before you open it.

If it wasn’t spam email, fake software updates could have been used. Those kinds of malicious software update offers could pop up when you visit questionable websites. It’s also not uncommon for those malicious update notifications to appear via adverts or banners. Although no person who knows how updates work will ever fall for it as they look very false. Since nothing legitimate and safe will be offered via such bogus alerts, be careful to stick to legitimate download sources. Take into account that if a program needs an update, the software will either automatically update or you’ll be notified via the application, not via your browser.

How does this malware behave

Needless to say your files aren’t openable. Soon after you opened the infected file, the ransomware started locking your files, likely without you noticing. Encrypted files will have an extension attached, which will help you find out which files have been locked. File encryption has been performed using a powerful encryption algorithm so attempting to open them is no use. A ransom note ought to also be visible and it should explain what happened to your files, and what should be done for their restoring. Generally, ransom notes follow a certain pattern, they use intimidating language to scare victims, demand payments and threaten to permanently remove files. Even if the hackers are in the possession of the decryptor, you won’t find many people suggesting giving into the demands. The people responsible for encrypting your files are not likely to feel obligated to restore them even if you pay. The same criminals could target you again because in their belief if you have paid once, you may pay again.

Instead of complying with the requests, try to recall whether you have stored files somewhere but have just forgotten. Because it is possible for malicious software researchers to make free decryption tools, if one isn’t currently available, back up your locked files for when/if it is. In any case, you need to remove .666 Files Ransomware from your system.

It’s rather important that you start backing up your files, and we expect this will be a lesson for you. Otherwise, you’ll end up in the same situation, with probably permanent file loss. So as to keep your files secure, you’ll have to buy backup, and there are a couple of options available, some more costly than others.
