4AGcf File Virus Ransomware Removal

4AGcf Ransomware is a file-encrypting malware. It secretly attacks the targeted PC and locks all the files using a very powerful encryption algorithm. It is programmed to extort ransom money from users in return for the decryption key. During encryption, it appends the “.4AGcf” file virus extension to the original file names.

For example, when it encodes a file originally named “1.jpg”, then it would appear as “1.jpg.4AGcf”. This converted file cannot be deciphered without the decryption key. It is a Babuk Ransomware variant and it leaves a ransom note after file encryption to demand money for the decryptor. Read this guide and follow the instructions to get rid of this infection and recover your files.

Threats like 4AGcf File Virus keep getting back on the PC if all associated files are not removed. So you are advised to use a powerful Malware Removal Tool to run a thorough scan of your PC and delete all threats at once.

What is 4AGcf Ransomware

4AGcf Ransomware is a data locker malware that encrypts all digital files on a compromised PC. It only converts files into the inaccessible format and then demands extortion money to restore files. This dubious threat is blackmailing malware that prevents users from accessing their personal files and forces them to pay money to reverse the encryption.

It is able to attack all versions of Windows computers without the permission of the user. Upon successful intrusion, it will scan the entire computer for files. Then it encrypts all the files on that PC which normally include but are not limited to video, audio, images, text documents, backup, archives, and so on.

Once done with the encryption, 4AGcf File Virus will leave a ransom note on the infected PC to inform victims about the attack. That note will contain all the information about this dubious malware and the ransom demand. The message on that note clearly states that the only way to recover encrypted files is by purchasing the decryption key. Although this ransomware claims to restore your files after paying the money, it is only a trick. Hackers are only intended in making illegal profits by cheating innocent victims.

What happened to your files

Ransomware infection has become a new reality these days. This dirty little malware can easily target your system and you won’t even know it. It will be too late when you will ever realize that your computer is infected and you cannot access your files anymore. There are so many ways through which your PC can get infected by 4AGcf Ransomware and you will only get to know about it when all is lost. This virus uses a very powerful military-grade cipher that is impossible to break without knowing the private key. That key is surely unique for every other computer and stored at a remote location, so there is no way to find it.

Once infecting your computer, 4AGcf File Virus will change all your files and you will lose access to your private information. It adds its own extension to mark files as locked, and you will need the decryption key to unlock such files and which you can only get from hackers for a price. This is illegal and sure very painful for the victim but cybercriminals are making good money out of it. Hackers don’t give you so much time to look for help, they also try to discourage you by threatening to delete your file completely.

Common ways of Ransomware Spreading

There are various ways through which malware like 4AGcf Ransomware can infect your system. One of them is by opening spam emails and attachments without scanning for viruses first. Cybercriminals often send fake emails pretending to be some genuine company or service provider. Users don’t give a second thought before opening such emails and malware slips into the computer secretly. One thing you should know is that all digital files like images, documents, pdf, .exe, etc. can carry infection.

Your PC can also get infected when you click on misleading pop-up ads and banners that appear on your screen while browsing the Internet. These advertisements mostly redirect your browser to suspicious websites that often host malicious codes which can trigger the automatic download of malware on your PC. Avoid browsing porn or torrent sites and downloading pirated software. They are commonly used by hackers to spread threats like this. We have created a list of safe practices that can help you protect your PC from further malware intrusion. Be sure to check those precautionary measures at the end of this article.

NEVER Pay Ransom Money

As I have already mentioned, do not pay ransom money to hackers. They are not intended to restore your files. No matter how tempted you are, first, you need to think it through. You don’t know hackers, payment is in BitCoin which cannot be traced, and after getting the money they don’t have any reason to decrypt your files. The only leverage they have on you is your files.

Once you pay, the creators of 4AGcf File Virus can leave you hanging. It’s better to use the backup to restore your files. If for any unfortunate reason you don’t have a backup or your backup files are also encrypted then still do not pay extortion. If you pay the ransom money to cybercriminals, there is no guarantee your files will get restored.

What to do after Ransomware infection

We strongly suggest you try to remove this virus. There is no way you can hope for a happy ending after paying money to hackers. If they give you a decryption key, then still virus is on your PC. It is highly possible that sometime later it will encrypt your files again using some other extension. So it is important that you use this removal guide to completely remove 4AGcf Ransomware from your computer. The Anti-malware tool suggested on this site can help you scan your PC for hidden threats and remove them all at once. You can also restore your files through any Data Recovery Software.

  • Check HTTPS before entering your email, password, credit card details, etc. to any site. Do not visit sites that do not have SSL security. Also, don’t forget to Enable Phishing and Malware protection in Browser.
  • Do not download or install any type of pirated software, games, or illegal patches. Avoid using shady sites to acquire freeware programs because they often use software bundling. Never install a program that asks you to inactivate your anti-virus software.
  • Avoid opening spam emails from unknown senders.  Always scan all the email attachments before opening them. Never click on any suspicious links with some too good to be true offers.
  • Connecting your PC or mobile devices to unsafe public Wi-Fi is not a good idea. You can also avoid unwanted threats coming from malicious sites by using a VPN to spoof your connection.
