Detected by Microsoft Defender Antivirus
Aliases: Backdoor.Win32.IRCBot.agv (Kaspersky)
Summary
Backdoor:Win32/IRCBot.BA is a Windows Messenger worm with backdoor Trojan functionality. The worm sends message to random Messenger contacts with a link to a remote Web site hosting a copy of the worm. If IRCBot.BA is run, it connects to an IRC server and waits to receive commands, such as to self-update, remove itself, download various programs and malware, or terminate running processes.
Backdoor:Win32/IRCBot.BA may download and install additional malicious software, thus manual removal is not recommended. To detect and remove this Trojan and other malicious software that may have been installed, run a full-system scan with an up-to-date antivirus product such as the Microsoft Safety Scanner (http://go.microsoft.com/fwlink/?LinkId=212742).
