Backdoor Trojan

The Geeks to Go website explains that Backdoor.Graybird refers to a family of trojan viruses, any one of which can gain access to a computer when a seemingly harmless or important file is downloaded. Sometimes referred to as Remote Access Trojans (RAT), these programs gain control of a computer and open a backdoor into the system to allow an attacker to access the files of a computer.


According to the PC1 News website, Backdoor.Graybird programs allow an attacker access to information stored on a computer, including passwords and personal data. Backdoor.Graybirds often spread by accessing the email address book stored on a computer and sending spam emails to contacts.
