Dear all,
Our network was attacked recently, our antivirus mcafee detect the attack as
bo:stack blocked by bufferflow. some computer was infected some of them was
our critical servers. the symptoms was everytime we logon to windows the
system "Generic Host Process for Win32 Services Error" it stop the server,
computer browser and distribute file services. These services is done by the
svchost.exe

My question is:
1. If the svchost.exe is corrupted is there anyway to replace the file with
another clean and functional svchost.exe?

Thanks you for the answers.

best regards,

Baron

It sounds like the Buffer Overflow detection kicked in in McAfee Enterprise v8.50i. Yes ?

You don't replace SVCHOSTS.EXE. That's the server of servers in Windows.

You have to find what was injected into the service.

Dear David,
That right, do you have any suggestion on how to trace this infection?
because it's cantaminating all the user PC's also. I think the mcafee still
blocking it. but some of our servers have been disable. how to fix it without
formatting the servers? because we tried to repair the windows but it didn't
work.
Thanks a lot for your answer.

You already have McAfee so use the following Multi AV Scanning Tool's Sophos and Trend
Micro modules to scan an infected server.

When using the Trend Micro module, you can disable the Spyware scanner capability.

You may want to concentrate on the c:\windows (c:\winnt) tree.

Download MULTI_AV.EXE from the URL --
http://www.pctip.ch/ds/28400/28470/Multi_AV.exe
or
http://212.98.39.7/ds/28400/28470/Multi_AV.exe

http://www.pctip.ch/downloads/dl/35905.asp
or
http://212.98.39.7/downloads/dl/35905.asp

English:
http://www.raymond.cc/blog/archives/2008/01/09/scan-your-computer-with-multiple-anti-virus-for-free/


To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
FireWall to allow it to download the needed AV vendor related files.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you can
download the files and perform a scan in Normal Mode. Once you have downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
file.

One More thing Dave before I try this on. is there anyway to update this
multiscan manualy? because the infected server cannot connect to the network
properly so it could not get an update from the internet. an also do you have
any suggestion to trace the source of this buffer overflow infection?
Thanks,

baron
