Trend Micro AntiRansomware is a free program designed to perform a quick system scan in order to identify and remove ransomware from an infected computer.

Ransomware is a type of malware that prevents or limits users from accessing their system. To make the infected system usable again, the victim is forced to pay (a ransom) to a remote threat actor thru certain online payment methods. Users may encounter this threat through different means. They can either download ransomware unwittingly by visiting malicious or compromised websites. It can also arrive as a payload, either dropped or downloaded by other malware. It is important to note, however, that paying for the ransom does not guarantee that users can eventually access the infected system.
