W32RPC virus?

I couldn't find that name, but I did find the following at McAfee.com that might be what you are looking for:

Name: Downloader-DM
Risk Assessment
- Home Users: Low-Profiled
- Corporate Users: Low-Profiled
Date Discovered: 8/2/2003

Virus Characteristics

-- Update August 04, 2003 --
The risk assessment of this threat was updated to Low-Profiled due to the c|net article Attack bot exploits Windows flaw.
This is not an email virus. This downloader trojan has been found within a self-extracting dropper package (possibly named worm.exe 113,507 bytes). The self-extracting archive carries 3 files.

The following files are contained within the dropper.
rpc.exe 40,960 bytes downloader trojan, tries to exploit MS03-026 to instruct a remote host to download lolx.exe from the infected host, via tftp, and run the downloaded exe
rpctest.exe 94,298 bytes MS03-026 exploit tool, creates remote shell on TCP port 57005
tftpd.exe 143,872 bytes haneWIN TFTP server

Other files associated with this threat are lolx.exe and dcomx.exe. The files are detected with the 4243+ dat files as W32/Lolol.worm.gen.

Indications of Infection

Presence of the following files on the root directory:
rpc.exe
rpctest.exe
tftpd.exe

Method of Infection

Trojans do not self-replicate. They are spread manually, often under the premise that the executable is something beneficial. Distribution channels include IRC, peer-to-peer networks, newsgroup postings, etc. Trojans may also be received as a result of poor security practices (weak username/password combination on open shares, lack of/or misconfigured firewall protection), or unpatched and vulnerable systems.

Removal Instructions

All Users:
Use specified engine and DAT files for detection and removal.

Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

Additional Windows ME/XP removal considerations

Aliases

Autorooter (Panda), Backdoor.IRC.Cirebot (Symantec), Mescaline, RPC Worm (F-Secure), Worm.Win32.Autorooter (AVP)
