More Information
Troj/CAPTCHA-A is a Trojan for the Windows platform.
Troj/CAPTCHA-A will claim that it is an adult game where entering the presented CAPTCHA codes results in progressively more explicit images of a young woman. The true implications of this are that the user is validating CAPTCHA codes for the use of malware authors and spammers.
Troj/CAPTCHA-A will create a new instance of Microsoft Internet Explorer and inject its malicious code into it in order to connect to the remote server.
