Dcom Exploit

My Avast online scanner keeps flashing up with a Dcom Exploit
88.107.???.???:135 /tcp (the ???.??? keeps changing. 251.156, 115.154 being
two of the combinations.) Am I being targeted by someone.
 
In addition could this be being caused due to upgrading to SP3? I know this
type of problem was addressed with sp2 but this seems to coincide with the
upgrade to sp3! I have tried a couple of ways to close down the DCOM port
135 but it is still showing as open. Anyone know any answers/solutions.

Not yet. This exploit seems to coincide with the installation of SP3. Up
until now I had never had this exploit happen. I have been running Avast for
quite a while now and this is the first time it has flagged this exploit.

Forgot to mention. I have already looked at the avast forum and i can only
find explanations and possible cures and have also tried one and currently
monitoring the solution. I am curious has to why the change?

[I meant to ask, "Where is Avast finding this?"]

If you can post a few links to pertinent threads in that forum, I'd
appreciate it.

Is the Windows Firewall or a third-party firewall enabled?

What anti-spyware applications might be installed (other than Defender)?
What third-party firewall (if any)? Was Avast and/or any of these other
applications running when you installed SP3?

How did you install SP3 (e.g., manually via Windows Update)? Was the
machine running WinXP SP1 or WinXP SP2 before SP3 was installed? Was the
machine fully patched before you installed SP3? Had you just reinstalled
Windows prior to installing SP3?

Can you successfully reach and scan for updates at Windows Update website?
Are any updates offered? If so, can you install them successfully?

Windows firewall is active and I am using the full home edition of Avast.
Also using Spybot S&D and regularily scan with Adaware. I do an AV and
spybot scans about twice a month.

The SP3 was a manual download direct from the Microsoft website and I still
had my resident scanners active when I installed it. I was fully up to date
with sp2 before I installed sp3

I have tried to reverse trace the different ip addresses that are flagged by
avast but no joy.

Here are some of the variations:

88.107.251.156
88.107.115.154
88.107.16.150
88.107.38.82
88.107.146.102
88.107.30.168

Avast flashes this message: dcom exploit 88.107.251.156:135 /tcp

One link I have tried but this solution did not work is

http://www.grc.com/freeware/dcom.htm

I can access and install updates from the windows update site. Just
installed a couple of office updates on thursday.

You are running XP, and I will assume this is a home machine.
You have no need for DCOM.
Go to Administrative Tools and select Component Services.
When it opens, click into Component Services / Computers
and right click on My Computer and select Properties.
In the My Computer Properties window that opens select
the Default Properties tab and make sure that the checkbox
Enable Distributed COM on this computer is NOT checked.
Avast might detect something coming in from the network but
if DCOM is not enabled it will not get a response.
Make sure you have a firewall enabled and that the exceptions
are all ones that you know about and need.

Check what exemptions are allowed in your firewall settings.
I am not aware of at what point in the network stack Avast might
be tying in, but the firewall should be disallowing tcp 135 traffic
from unknown machine addresses. If you use filesharing in your
home network you do need tcp 135 to be available to those boxes,
but it should not be open to the world.

I checked the Dcom setting was unchecked in component services last night but
I am still getting the exploit warning. Could someone unscrupulous be trying
to access my machine and eventually give up? Could this attack be from
someone obtaining my ip address through other sites, for example, facebook.
I only ask because my partner signed up recently to it. I have run XP home
for quite a while now and this has never cropped up before.

IMHO, no, it's just normal network pinging, judging from the information
you've posted in this thread.

Is Avast configured to automatically seek updates as least once a day?

Are you now running Avast v4.8.1201? There have been two (2) program
updates for Avast v4.8 since 12 May 2008:
http://www.avast.com/eng/avast-4-home_pro-...on-history.html

The above notwithstanding, the fact that you installed SP3 without having
first disabled all real-time protections may be related to the reports
you're seeing from Avast now. I'd recommend posting about this in a new
thread in the appropriate Avast Support Forum before doing anything else
about it: http://forum.avast.com/index.php?board=2.0

Good, then what they are trying, IF Avast is accurately
reporting, will not work. There was a remote DCOM
exploit some years back that someone's infected machine
might be using, among other things, in attempt to spread
itself. If I were you I would not be thinking this is at all
related to XP SP3 but I would be looking at my firewall
to see why the packets got that far.

As far as I can tell Avast is stopping the attempts (therefore I am
protected). So far it has not happened today. What exactly do you mean by
"looking at my firewall to see why the packets got that far." Could someone
be deliberately trying to access my computer this way?

Someone could, but more likely someone's machine is via some
infection that the owning someone is not even aware is there

Thank you for your reply. You have given the most plausible explanation so
far. If I send a global message to the friends list on facebook, (someone on
the friends list seems like the most obvious source,) can you tell me the
most likely virus name to inform them to look for?

No, I cannot. This may have nothing whatsoever to do with
emails or websites you have visited. It can be some machine
on the network that "decided" to try at your current IP address,
with no prior awareness of who you are, that you or your comp
exist, etc..
Lee, this stuff happens all the time. It is the source of the personal
firewall, and of the anti-malware industries.
