Hello,

When running webroot's spysweeper, it indicates I'm infected with vertumonde and it won't fix it (or it seems to and a retest shows the same problem). Running sunbelt's conunter spy gives me a clean scan.

When viewing entries with hijackThis, I noticed and entry for catdoc.dll. I can't find any information about the dll nor can I remove with any of the methods I've tried: hiJackthis, MoveOnBoot, etc.

Any idea what this dll is? Need I worry about it? Thanks in advance for your time and expertise!!! Here's my hijackThis log file:

Greetings and welcome to TomCoyote.org!

Before you can be helped, you MUST upgrade to Hijack This! v1.99.1

Links to Hijack This! v 1.99.1:

Hijack This! at tools.radiosplace.com

Hijack This! at spywarewarrior.com

After downloading the new version, do this:

Run Hijack This!

Click the "Open the Misc Tools section" button.

Click the "Open process manager" button.

Check the "Show DLLs" box (upper right).

Click on each item in the upper window, then look in the lower window.

Check to see which processes are using C:\WINDOWS\AppPatch\catdoc.dll

Post back letting me know all processes using that DLL.

Copy the text in the following quote box into Notepad:

dir C:\WINDOWS\AppPatch\ /ah > files.txt
dir C:\WINDOWS\AppPatch\ >> files.txt
notepad files.txt


Save it to your desktop as ff.bat.

Close Notepad

Now, the ff.bat file on the desktop.

Wait for a Notepad window to open up.

Please paste it's contents into your next post.
:)

Thank you for the fast response. I followed your excellent instructions. The results output from the newer version of hijackThis are:

catdoc.dll is used by only the c:\windows\explorer.exe process.

Below are the results of ff.bat:

Man – you guys don't mess around! Thank you, thank you – you're awesome!

OK – I ran the procedure per your instructions. When HijackThis fired up during the Killvundo.bat execution, the 02-BHO: MSEvents Object . . . C:\WINDOWS\AppPatch\catdoc.dll entry was missing. The second 020 entry "Winlogon Notify . . . etc. was there and I deleted it per your instructions, just thought you should know.

Here is the vundofix.txt file:

Looks good!!! :thumbup:

GOD bless you!!!

M68 :)

Items you may wish to consider to harden your defenses against future infections:

Read "How did I get infected in the first place?"

Download/install IE-Spyad

IE-Spyad puts over 4000 known malicious web sites into IE's "restricted zone" to help prevent you from getting infected.

Check your browser settings at Qualsys.com

A series of "tests" (and suggested fixes) to help tweak IE's settings to help prevent infections when surfing the web.

Follow safe Internet practices:

1. Keep your virus definitions up to date, and scan your system regularly.

2. Don't open email, or download attachments from unrecognized email addresses.

3. Be careful when downloading email attachments, EVEN FROM PEOPLE YOU KNOW! Many virii, worms, and trojans infect a persons system then immeadiately spread themselves to the people in the infected persons addressbook via email attachments.

4. Be careful downloading files from the Internet. Scan all downloaded files with a reliable UP-TO-DATE antivirus program. Scan "zip" files BEFORE unzipping, and scan all unzipped files BEFORE USING THEM.

5. Keep your Windows and IE current with all the latest patches and updates.
