Graybird is a Trojan horse that hides its presence on compromised computers and downloads files from remote Web sites.
Graybird is classified as a backdoor Trojan horse, which means it allows attackers to gain remote control over infected machines.
[1][2] The Trojan can be delivered through various means, such as being bundled with other malware or downloaded unknowingly by users visiting malicious websites.
The development of Graybird has seen a decline, with reports indicating that its creators abandoned the project in March 2007 due to decreased effectiveness and the emergence of more advanced malware.
[3] To combat infections, users are advised to utilize antivirus software and tools like HijackThis, which can help identify and remove malicious files from affected systems.
