- Application communicates with remote servers
What are Potentially Unsafe Applications?
There are many legitimate programs that serve to simplify administration of networked computers. However, in the wrong hands, they may be misused for malicious purposes. This is why ESET has created this special category. Our users now have the option to choose whether the antivirus system should or should not detect such threats. "Potentially unsafe applications” is the classification used for commercial, legitimate software. This classification includes programs such as remote access tools, password-cracking applications, and keyloggers (programs that record each keystroke a user types).
If you find that there is a potentially unsafe application present and running on your computer (and you did not install it), please consult your network administrator or remove the application.
