AgeLocker (.sthd2 file) ransomware is a malicious program designed to block access to users' files and demand money for a decryption tool

AgeLocker ransomwareAgeLocker ransomware is a cryptovirus that locks your files.

AgeLocker ransomware is a cryptovirus[1] that encrypts data in the infected device. This ransomware[2] also is known as .sthd2 file virus because all infected files get .sthd2 extension. The infection encrypts all types of files, such as pictures, video, banking data, or backups.

AgeLocker virus is a little bit different than other ransomware because it is using the age encryption library/binary of the cryptographer Filippo Valsorda. The victims get a ransom note via email.

All damaged data becomes inaccessible to victims. It is important to remember, that if the user tries to remove AgeLocker .sthd2 file virus, infected files still remain inaccessible. Nonetheless, malware termination is a necessary procedure if you want to avoid the encryption of the incoming files.

AgeLocker ransomware removalAgeLocker ransomware is a virus that demads money from the victim after it the file encryption.

Avoid paying cybercriminals to recover .sthd2 files

While criminals are demanding to pay the ransom, cybersecurity experts[3] strongly recommend not doing so. Although hackers want your money, there is no guarantee that even if you satisfy all requirements the decryption code will be granted to you. It is possible that you will be left not only without your .sthd2 files but also without money.

Instead, if you have no backups, we recommend trying alternative methods listed below for .sthd2 file recovery. In some cases, malware might fail to perform actions that it is meant to do, in which case data retrieval could be possible (for example, if the AgeLocker virus fails to delete Shadow Volume Copies).

Also, try to remember that you should be extra careful on the internet because such threats like ransomware are spreading through different sources. For example, you can download the infection through malicious attachments in e-mail messages, unofficial websites, or download it together with fake software cracking tools, keyloggers, etc.

Remove AgeLocker ransomware from your computer to avoid more damage

As we stated before, you should remove AgeLocker ransomware from your computer. You can do it manually or use an anti-malware program such as SpyHunter 5Combo Cleaner or Malwarebytes. After the deletion, you may try to recover your files if you have backups in online servers or different devices. Also, remember to use such a tool as ReimageIntego if you want to fix any OS damage.

AgeLocker ransomware removalInstead of paying for criminals, you should rely on backups.

Unfortunately, manual decryption is almost impossible. Even after AgeLocker virus removal, your infected files will stay encrypted. But you still should avoid talking to criminals or paying money because there is no guarantee that they help you.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
