Free bootable antivirus that cleans infections from outside Windows - even when the PC will not start.
Kaspersky Rescue Disk is a free bootable antivirus for Windows PCs that are too infected to clean normally.
You start the computer from a USB stick instead of Windows. Because the malware never loads, it cannot hide or block the scan.
That makes it effective against rootkits, bootkits, ransomware lockers and other threats that survive regular antivirus scans.
Malware is not running, so it cannot defend itself or hide files.
Checks boot sectors and system areas that are invisible from inside Windows.
Downloads the latest signatures over the network before each scan.
Copy important files to an external drive before you clean anything.

Yes. It is free for personal and commercial use and does not require a licence key.
It removes the ransomware program and screen lockers. It cannot decrypt files that were already encrypted - for that, check the free decryptors at nomoreransom.org.
Check that the stick is first in the boot menu. On some UEFI PCs you may need to disable Secure Boot temporarily in the firmware settings - turn it back on after cleaning.
It only removes or quarantines infected objects. Your documents and photos are not touched unless they are infected.
