To solve the problem, the creator of the ransomware will always try to extort money from you. Find out in this guide everything you need to know about ransomware and what they are best anti ransomwareto complement your classic antivirus and programs to decrypt compromised files.
How does ransomware work?
THE ransomware they are malware with characteristics similar to trojans and worms (at least as regards their spread). They are very difficult to tackle and eradicate, to the point of having become one of the greatest dangers when surfing on PC! These malware can be taken in several ways:
- By installing crack for programs, games or services
- By opening an email with specially infected files
and various other ways, always very subtle. Once "infected", a screen with a non-removable image will appear on your PC. Often this screen was represented by messages regarding the postal police, an alleged lawyer, the FBI or the US Department of Justice. This screen provides the information to remove it, ie how to pay the creators of this malware (a real extortion). The usually requested payment method uses electronic coins, such as bitcoin and other cryptocurrencies.
As if that were not enough, in addition to the total block of the PC, the ransomware also encrypts some most of the files present in your PC and makes them unusable. Each ransomware acts differently by encrypting the data with different methods and characteristics, which is why the various protection software must create specific solutions as new threats emerge.
For many, the only way to get back the PC and the locked files was to pay, but luckily most of these malware have been neutralized and the encrypted files unlocked thanks to the decryption tools, which we will suggest in this article.
