hmm that sounds like a network spreading worm to me...

if SheharyaarSaahils method fails get a copy of the kaspersky virus scanner
==> http://www.kaspersky.com/trials
and scan one of the pcs with it.. i'm pretty sure that it will catch the virus and remove it..

if it does.. i would suggest you to disconnect each pc from the network..
or just disable the connection in the connection dialog and start to clean up every single pc that is infected with it..
and not connecting one back till each of them are cleaned!
Hey Brendle, =]

Identifing the virus:
Since it's on 4 different computer this is obviously a network issue, which is obviously a worm. Now, do you have any protection on the exchange server to prevent these types of attacks?  I would run a free online scan @: http://housecall.trendmicro.com/housecall/start_corp.asp  - just to verify what type of worm/trojan your dealing with.

Removal & Prevention:
Trend Micro Client/Server/Messaging Suite is great to handle all your security needs for a network.
"Trend Micro Client/Server/Messaging Suite provides a powerful, multi-layered defense against viruses, spyware, and other malicious code, to protect mail servers, file servers, and desktops. The suite of integrated products can be remotely configured and managed to create the right mix of security and performance for any organization."

http://www.trendmicro.com/en/products/suites/c-s-m-suite/evaluate/overview.htm  - That link will provide you with all the features, benefits and info on the product. ALso gives a 30 evaluation trial.

If you'd like to keep Norton and just addon security for exchange server to prevent these types of attacks from happening again, I recommend:

GFI MailSecurity: TO KEEP worms/viruses/spyware out of your mail servers.

GFiLANguard: This is a wonderful program to perform security audits and receive alerts of attacks and other critical events.

GFi products are a little on the higher budget side, however very effective products.

Let me know if you have any questions or concerns!!

good luck,


svchost.exe is the legit version but svchost32.exe is not (on XP anyway).

It would be wise to check the version information of the file.

If there is no version information then it is most definetly a virus.

knoxj81  I allready use GFI products and YES! I do agree they are great.

SheharyaarSaahil - Thanks for all the help. I was not able to identify the virus but I turned port 445 off(the flood) and deleted the file.
