One of the most famous and used tools to clean up your PC from threats is definitely MalwareBytes Anti-malware, available in free version (with trial period of 14 days) .
Immediately the program will check all areas of the PC in search of the threats supported, so you can remove them automatically.
This program is particularly effective against Trojans, worms, spyware and ransomware, so it's always good to use it when we suspect an infection.
The Premium version (with real-time control coupled with the antivirus) is offered for 14 days free; at the end of the trial period you can always use the program for manual scans but the real-time control will be deactivated until we obtain a user license.
In our case the free version is fine so we can install it without problems.
