The proposed disc allows you to carry out a full anti-virus scan to detect and remove viruses, trojans, rootkits, worms, spyware and ransomware without starting the main operating system installed on your computer (MS Windows, macOS, Linux, Android, etc.). The use of an external drive does not allow malware to oppose the neutralization and recovery of an infected system. Data validation is supported on FAT, FAT32, exFAT, NTFS, HFS, HFS+, btrfs, e2fs, ext2, ext3, ext4, jfs, nilfs, reiserfs, reiser4, xfs, and zfs file systems.
