WinOpts.B is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
- On remote sites: it mass mails junk mail (spam).
It uses several methods in order to avoid detection by antivirus companies:

WinOpts.B uses the following propagation or distribution methods:

- Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
