What Is Trojan.Refroso?

Trojan.Refroso is a type of Trojan malware that can infect your system through various means, such as downloading infected software, opening malicious email attachments, or visiting compromised websites.

The malware can also install additional malware, such as keyloggers, ransomware, or spyware, to further compromise your system. Additionally, Trojan.Refroso can modify system settings, disable security software, and create new user accounts to maintain its presence on the infected system.

You may also notice that your system is crashing frequently, or that your browser is being redirected to unfamiliar websites.
