Forma ransomware virusForma ransomware is a product of Hidden Tear based malware product developers who focus on money extortion.

Forma ransomware is yet another file locker that is based on HiddenTear open source virus. This time, however, it targets Polish computer users exclusively. Malware employs AES encryption[1] algorithm for data locking process and appends a .locked extension to all photos, videos, databases, documents, etc., preventing victims from accessing any of personal files. Forma virus changes the desktop wallpaper and drops a ransom note ODSZYFRFUJ_PLIKI_TERAZ.txt which explains to users how to retrieve the encoded data. Experts highly discourage users from contacting cybercriminals, especially when security researchers can help victims with file decryption. Note that the added .locked extension is used by several other viruses, so you should check your ransom note for the correct virus name.

When it comes to trojans, crypto mining malware or ransomware infections spam emails with infected attachments spread the code widely and quickly. Email scams are often used to demand payments from victims directly,[4] but emails that distribute malware are set to trick users into opening attached files.

How to prevent from getting ransomware

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.
