Trend Micro Ransomware Screen Unlocker Tool is a free program for Microsoft Windows operating systems that helps you unlock the screen after ransomware attacks.
As you may know, there are two general types of ransomware: those that lock the screen, and those that encrypt files. Screen lockers use various methods to block you from getting in the system by blocking access to it.
Some may only do so when the system is booted regularly, others may also block you from accessing Safe Mode on top of that.
Trend Micro’s program has been designed to unlock Windows devices that are affected by lock screen ransomware.

The application is offered in two versions: first a regular version that you run in the Safe Mode environment. Second, a version for USB that you boot from if Safe Mode is locked as well.
The Safe Mode version requires that you boot the PC into Safe Mode. While that is easy on older versions of Windows — tap on F8 rapidly during boot — it may be nearly impossible on newer versions if you cannot access the settings anymore.
If you manage to get in Safe Mode, simply run the program in the environment to install it on the system.
Reboot into the normal mode of the Windows operating system afterwards, and use the keyboard shortcut Ctrl-Alt-T-I to trugger the program. Trend Micro notes that the hotkey works locally only and not through remote sessions. Also, it may need to be activated more than once before it works.
The screen lock should terminate and the main Ransomware Screen Unlocker Tool program window should appear on the monitor.
Click on the scan button to scan the system for ransomware files. Files found by the application are listed in the interface. You may review those, select files that are malicious, and hit the clean button afterwards to delete them from the system.
All that is left to do then is to click on the reboot button to restart the system. The ransomware threat should have been removed on the next start.
The USB version of the ransomware unlocker tool works in a different way. When you run it you are asked to pick a USB device you want the program to be copied on.
You need to boot the computer from USB to load the program on startup of the device. Log in to the infected computer afterwards, and wait for the Ransomware Screen Unlocker Tool window to unlock the screen and display the same program interface you see on the first screenshot.
