.Calum file ransomware – How to remove

Is .Calum file ransomware a serious malware

.Calum file ransomware might lead to serious harm as it’ll leave your data locked. Ransomware is classified as highly harmful malware because of the consequences the infection may have. As soon as it launches, it’ll start scanning for and encrypting certain file types. Ransomware targets particular files, and those files have the most value to victims. Once files are encrypted, they can’t be opened unless they’re decrypted with specific decryption software, which is in the hands of cyber criminals who were the ones who made/distributed this ransomware. There is some good news because the ransomware is every now and then cracked by people specializing in malicious software, and they might release a free decryptor. This is your best choice if you have not made backup.

You’ll see a ransom note either on the desktop or in folders that have encrypted files. There is no doubt hackers behind this malware want to make as much money as possible, so you’ll be demanded to pay for a decryptor if you want to be able to open your files ever again. While we cannot force you to do anything as we’re talking about your files but paying for a decryption tool is not suggested. It’s not that hard to imagine criminals simply taking your money while not providing a decryption tool. Keep in mind that there’s nothing stopping them from doing so. Consider using that money to purchase backup. In case you have made copies of your files, simply eliminate .Calum file ransomware.

In the next section, we will discuss how the malware got inside your OS, but in short, you probably ran into it in spam emails and fake updates. The reason we say you most probably got it through those methods is because they’re the most popular among cyber crooks.

Ransomware spread ways

Even though your device may get contaminated in many ways, the most likely way you acquired it was via spam email or bogus update. Become familiar with how to spot malicious spam emails, if you got the malware from emails. When dealing with unknown senders, you need to carefully check the email before opening the file attached. Senders of dangerous spam often pretend to be from familiar companies so that users lower their guard and open emails without thinking. The sender could claim to be Amazon, for example, and that they’re emailing you because your account displayed weird behavior or that a purchase was made. If the sender is who they say they are, checking that shouldn’t be hard. Check the sender’s email address, and however real it looks initially, check that it really is used by the company they say to be from. Furthermore, email attachments need to be scanned with reliable scanners before you open them.

Bogus software updates are another way to get the infection. High-risk sites are the most likely place where you could have encountered the bogus update alerts. Those bogus update offers might also appear in advertisements and banners. Although people who know how updates work will never engage with them as they’ll be obviously fake. If you continue to download from dubious sources, you will end up with all types of junk on your system. The software itself will alert you when an update is necessary, or it might update itself automatically.

What does this malware do

Ransomware has locked your files, which is why you cannot open then. Soon after the malware file was opened, the ransomware started the encryption process, probably without you noticing. Files that have been affected will now have a file extension added to them, which will help you differentiate between affected files. Attempting to open those files won’t get you anywhere because a complex encryption algorithm was used to lock them. You’ll then find a ransom notification, where crooks will say that your files have been encrypted, and how to go about recovering them. The ransom notes generally threaten users with file deletion and strongly encourage victims to pay the ransom. It is not impossible that crooks behind this ransomware have the only available decryptor but even if that’s true, it’s not recommended to pay the ransom. Even after you pay, it is unlikely that cyber crooks will feel a sense of obligation to aid you. Furthermore, if crooks know that you paid once, they could try targeting you again.

It may be the case that you have uploaded some of your files somewhere, so check that. Our recommendation would be to store all of your locked files somewhere, for when or if specialists specializing in malware make a free decryption tool. It is important that you remove .Calum file ransomware from your computer as quickly as possible, in any case.

Backing up your files is essential so hopefully you’ll begin doing that. You could be put into a similar situation again and risk file loss if you don’t take the time to do backups. Backup prices vary based on in which backup option you choose, but the investment is absolutely worth it if you have files you don’t want to lose.
