If so, GANDCRAB may stop the infection process and self-delete. Other activities include creating files in %AppData% and other system directories and also creating mutexes.

The encryption process of GANDCRAB 5.3 is rather complicated. The virus may target files of the following types:
- Images.
- Videos.
- Audio files.
- Documents.

Once the files are encrypted, they do start to appear with a changed extension and the user cannot open them. Paying the ransom is not recommended, since you cannot possibly trust the ones behind GANDCRAB and by paying you support their cyber-criminal activity. Instead, we advise you to remove the virus and backup your files, even if they are encoded.
