What virus ? This is Exploit code, not a virus !!!

It crash's becuase there is a bug in the code that causes a Buffer Overflow condition. It
is ibn this state that malware can take control of the system.

I have made it easy. Here's my self installing unofficial patch...

I believe I have already said to you in another thread, McAfee's wording
is...

Download file: G:\Temporary Internet
Trojan name: Exploit.VMLFill
McAfee Shield: Virus found in download file!

I get a choice to Continue, Delete, or Move. Choosing Move, I end up
with "testvml[1].htm.vir" in "G:\Infected". Hmm, now I see a .log there.
It contains just one line...
www.isotf.org => testvml[1].htm.vir

WELL, McAfee does give a choice of 3 what to call it, actually. I have
taken the .dll already as Bear said, with Winzip. Yet I haven't
installed it.

Gee... three conflicts all in one message !

Trojan <> virus <> exploit

McAfee (or any other AV software for that matter) creates a default message and then
concatenates what's found to the default message.

If you test the EICAR, see what it calls it !

I'll say it again, again... There is NO virus, this is an Exploit Code.

The fact is if you are using the TEST URL http://www.isotf.org/zert/testvml.htm there isn't
even a payload. It just creates a Buffer Overflow condition. McAfee is flagging the Buffer
Overflow condition or the test for it (I can't which).

Here is is in FireFox... (No virus statement here in Enterprise v7.1)

So it is YOUR version generated this incorrect statement and this reatail version was
discontinued YEARS ago. PCR, I believe you are still using Retail VirusScan v5.x.

One more time...

There is NO virus, this is purely Exploit Code and this URL has NO payload !

McAfee's wording is...

Download file: G:\Temporary Internet
Trojan name: Exploit.VMLFill
Click to expand...

McAfee found with it thinks is a virus.

What it found was (for lack of a better word) a shell of a virus. It
has the fingerprints and characteristics of exploit code. It has no
payload (that's what makes it safe to execute). McAfee doesn't know
that it doesn't have a payload. It has the characteristics of the VML
exploit, so that's what it calls it.
So... does IE need the exploit file of 98 Guy to deliver the
exploit?
Click to expand...

The .htm file posted earlier contains specially crafted code that
triggers a fault in IE that causes IE to crash. That's all it does.
In it's nasty form, there would be additional code that would be
executed in conjunction with IE crashing.
Is the exploit file extraneous to the delivery of the
exploit?
Click to expand...

The exploit code opens a door into the operating system. Think of it
as a key. If there is nothing accompanying the key (the payload) then
there is nothing to "get in". AV software detects the key - because
the payload can vary but the key must remain relatively similar or
static.

So we know what the key looks like. What is the lock? The lock in
this case is the vgx.dll file. You can either remove the file from
your system (and hence the key has nowhere to go) or update the file
(plug the keyhole).

McAfee gives me a choice of three! I'll have to try the Eicar tests...
http://www.eicar.org/anti_virus_test_file.htm
...., as he suggested. Oooo, it calls all 4 of those just a virus!
Therefore, it does seem McAfee can discriminate in it's error message--
& it's being generous what one may call this new thing!
