What is 4o4 ransomware

4o4 ransomware is a highly severe malware infection, that might lead to permanently encrypted files. It’s commonly referred to as ransomware. If you recall having opened a spam email attachment, clicking on a strange advertisement or downloading from untrustworthy sources, that’s how the threat might have entered your computer. It will be explained how you can safeguard your computer from such threats further on in the report. Become familiar with how ransomware is spread, because there might be dire consequences otherwise. If you aren’t familiar with this type of infection, it may be rather shocking to see encrypted files. A ransom message should make an appearance soon after the files become locked, and it will explain that you need to pay money in exchange for a decryptor. Do keep in mind that you are dealing with hackers and it is unlikely that they’ll feel any obligation to aid you. It would be more likely that you won’t get a decryption tool. Ransomware does hundreds of millions of dollars of damages to businesses, and by paying, you’d only be supporting that. Something else you ought to consider is that a malicious software researcher might have been able to crack the ransomware, which means a free decryptor might be available. Look into other data recovery options, including the possibility of a free decryption utility, before you make any hurried decisions to pay. For those with backup available, you simply need to erase 4o4 ransomware and then restore files from backup.

How to prevent a ransomware contamination

You could have gotten infected in various ways, which will be discussed in a more detailed manner. It isn’t unusual for ransomware to use more sophisticated methods to contaminate devices, although it generally employs the basic ones. Spam email and malicious downloads are the popular methods among low-level ransomware authors/distributors as they don’t require a lot of skill. Contamination via spam email is still one of the most frequent ways people get their machines infected. Hackers have large databases with possible victim email addresses, and all that is needed to be done is write a semi-convincing email and add the contaminated file to it. Typically, those emails have hints of being bogus, but if you have never encountered them before, it might not be so. Mistakes in the text and a non legitimate looking sender address are one of the signs that you might be dealing with malware. What you might also notice is known company names used because that would put you at ease. Thus, even if you know the sender, always check the email address. In addition, if your name is not used in the greeting, or anywhere else in the email, it should raise suspicion. If a company with whom you have had business before emails you, instead of greetings like Member or User, your name will always be used. So if you’re an Amazon customer, and they email you about something, they’ll address you by name, and not as Member, etc.

In case you want the shortened version of this section, always check that the sender is legitimate before you open an attachment. We also do not advise clicking on ads hosted on sites with suspicious reputation. If you’re not cautious, ransomware might be authorized to enter your machine. Even if the advert is advertising something you may be interested in, keep in mind that it could be completely false. Furthermore, you should stop downloading from questionable sources. If Torrents are your preferred download source, at least only download torrents that were downloaded by other people. Another infection method is through software vulnerabilities, the malware might use those flaws to contaminate a machine. Ensure your programs are always updated because of this. All you need to do is install the updates, which are released by software vendors when the flaw becomes known.

What happened to your files

If you launch the ransomware malware file, it will scan your device for certain files to encrypt. Its prime targets are documents and photos, as they likely will be valuable to you. Once the files are found, they’ll be encrypted with a powerful encryption algorithm. If you are uncertain which files were locked, the unfamiliar file extensions added to all encrypted ones will help you. You’ll be unable to open them, and a ransom message should soon appear, which ought to contain information about paying a ransom in exchange for a decryptor. Ransomware demand different amounts, the decryptor may cost $100 or a even up to $1000. We’ve already mentioned why paying is not advised, but in the end, the decision is yours. You ought to also look into other ways you may be able to recover your data. A free decryptor might be available, if a malware specialist was able to crack the ransomware. Maybe a backup is available and you simply don’t remember it. Your device makes copies of your files, which are known as Shadow copies, and if the ransomware didn’t erase them, you might restore them via Shadow Explorer. If you haven’t done it yet, we hope you invest in some kind of backup soon, so that your files aren’t at risk again. If you just realized that you did make backup prior to the infection happening, you just have to remove 4o4 ransomware, and can then proceed to recover files.

Ways to delete 4o4 ransomware

Unless you’re absolutely sure about what you are doing, we don’t recommend you try manual removal. While it is it isn’t impossible, you may end up permanently damaging your device. It would be safer if you employed an anti-malware tool for such threat elimination. Those tools are made to erase 4o4 ransomware or similarly harmful infections, so you should not run into trouble. Your files will not be recovered by the tool, because it isn’t capable of doing that. File restoring will be yours to perform.
