If ransomware encrypts only certain files but spares others, what factors might have led to this selective encryption?
What happens if I get infected with ransomware and all files on my user are encrypted, but my drive D files and files on other users aren’t?

Ransomware may selectively encrypt certain files based on file types, locations, or other criteria set by the attackers. This can be part of the ransomware strategy to maximize the impact on the victim while minimizing their chance of losing the most critical data.
If ransomware only encrypts some files while leaving others unaffected, it’s crucial to immediately disconnect the infected system from any network to prevent further spread. Then, a thorough malware scan and removal process should be conducted using reputable antivirus software. Additionally, affected files should be identified and isolated to prevent further damage. Having a robust data backup system in place is essential for restoring encrypted files without having to pay the ransom.
Ransomware can selectively encrypt certain files based on factors such as file types, file locations, file sizes, or specific file extensions. Some ransomware may target files commonly used or those with higher potential financial value, while others may avoid critical system files to ensure the system remains operational for the victim to pay the ransom. Additionally, the ransomware may include specific algorithms or criteria for determining which files to encrypt, allowing for selective targeting.
