Subject: backdoor irc

I need some help and wonder whether anyone can offer any to me

I believe I have had a system hacked/compromised, I have checked the system
and found these files,

c:\mIRC\Execs\Zfn4.exe

c:\mIRC\Execs\Die3nt.exe


I believe someone may have used to gain access into the system. It was a
patched win2k system.

I am looking for details on what these programs do, and how they are
activated or how control is gained through them



Symantec have the Zfn4.exe listed as Backdoor.IRC.Flood

http://securityresponse.symantec.com/avcenter/venc/data/backdoor.irc.flood.html

There website states "Backdoor.IRC.Flood is a backdoor Trojan. It installs
an mIRC client that has backdoor capabilities; this gives the hacker
unlimited access to the computer."




Pestcontrol lists the Die3nt.exe also as a trojan.

http://research.pestpatrol.com/Search/FileInfoResults.asp?MD5=f53a0574933fbed6740fef49cb76ff55




But I am having a few problems actually finding out anything else about the
files. has anyone any insight into how they work , what they do, how does a
person connect to a system via them. how far could a person get into the
system through these files, symantec seem quite clear that a hacker would
have unlimited access, but nowhere else can i find anything about this.






Thanks for your Time.
