Windows Defender Antivirus detects and removes this threat.
This ransomware can stop you from using your PC or accessing your data. It might ask you to pay money to a malicious hacker.
The trend towards increasingly sophisticated malware behavior, highlighted by the use of exploits and other attack vectors, makes older platforms so much more susceptible to ransomware attacks. From June to November 2017, Windows 7 devices were 3.4 times more likely to encounter ransomware compared to Windows 10 devices.
