Summary
Worm:Win32/Neeris.C is a chat client worm with backdoor Trojan functionality. The worm uses API calls for both Windows Messenger and AOL Messenger to send messages to contacts, with an attached file containing a copy of the worm. Worm:Win32/Neeris.C 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.
Worm:Win32/Neeris.C 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).
