The DecryptorMax Ransomware or CryptInfinite Ransomware is a file encryptor that modifies your files and displays requests for payment in return for undoing its attacks. As with any other file encryptor, the most direct defense against the DecryptorMax Ransomware's payload is to use a regular backup system, and malware experts don't recommend paying its 'fee.' Despite this Trojan's claims of using supposedly military coding standards, uninstalling the CryptInfinite Ransomware should be viable with most competent brands of anti-malware software.

The DecryptorMax Ransomware: A Maximum Ransom for a Minimum of Effort

The DecryptorMax Ransomware is a representative of the ongoing popularity of file encryption as a means of extorting money from random individuals by holding their data hostage. The DecryptorMax Ransomware may install itself through a malvertising pop-up, compromised e-mail attachments or other, non-consensual means, after which the DecryptorMax Ransomware scans your hard drive for files to encrypt. The files under attack by the CryptInfinite Ransomware include images such as JPG, spreadsheets, text documents and other, equally common formats.

The DecryptorMax Ransomware claims to be modifying all affected files with a 'military grade' encryption algorithm, although malware researchers have seen no evidence of such capabilities, and no indications that the DecryptorMax Ransomware includes superior coding to other, relatively simple file encryptors. However, even a simple encryption algorithm can prevent other programs from opening the affected files.

With its encryption attack accomplished, the CryptInfinite Ransomware loads instructions for paying its ransom. The DecryptorMax Ransomware may demand payments of up to 500 USD, with no real guarantee that its administrators will transfer any associated decryption key to the PC's user. Like most file encryption Trojans of late, the DecryptorMax Ransomware also adds urgency to the ransom attack with a strict, twenty-four-hour time limit.

Saving Hostage Files without Maxing out Your Debt

Because of the ever-present risk of third parties taking ransom payments without providing anything in return, submitting to file-ransoming attacks never is an ideal or recommended solution. You can prevent the DecryptorMax Ransomware from harming your files permanently by keeping those files backed up on a remote cloud server or external device. Note that, since Trojans like the DecryptorMax Ransomware may scan for currently-attached storage devices, your backup devices should be left unplugged when not in use.

PCs infected with the CryptInfinite Ransomware may have their Registries modified, in addition to any other issues present. However, standard safety features like Safe Mode can prevent threats from launching automatically. With the DecryptorMax Ransomware no longer loading, you can scan your PC with any trusted anti-malware program and delete the DecryptorMax Ransomware without causing any further harm to the encrypted files.

The DecryptorMax Ransomware's choices in file formats for encryption attacks may indicate preferences for Windows-based machines. However, malware researchers are continuing to investigate the extent of systems affected by the CryptInfinite Ransomware, along with identifying its distribution exploits.
