Post #1
I would be hugely in debt to anyone who can give me some direction on resolving my hugely persistant virus/malware problem.

I cm continually detecting trojan virus's in my local settings temp folder.

The following are typical examples of the detected threats as reported by AVG Free

File Name - 49exhdd.8.exe
Trojan Horse Generic 2 AUF
Source - backup copy

File name - 74exhdd.6.exe
Trojan Horse Downloader Generic 2 NSJ
Source - backup copy

I am running the following defenses at present

AVG Free Edition 7.1.405
Spyware Fighter
Ewido anti spyware ver 4.0
Zone Alarm


The virus's detected are either tojan downloaders or trogan proxy's (I have blocked my PC from sending out the resulting spam emails).

I have extensively googled the problem and that has led me here!

I have run HJT and post my log below. Any advice or direction would be really really helpful!

Many thanks

Welcome to the forum :wavey:

Please download ATF Cleaner by Atribune.
Download - ATF Cleaner»
This program is for XP and Windows 2000 only

Don't run it yet.

CLOSE ALL WINDOWS (even this one) AND PROGRAMS!!!!

Run Hijack This!
Click "Do a systen scan only".
Then "check" the box to the left of these item(s):

O4 - HKLM\..\Run: [.nvsvc] C:\WINNT\system\smss.exe /w

O23 - Service: Windows Log - Unknown owner - C:\WINNT\system32\nvsvcd.exe

Then click "Fix checked" and close Hijack This!.

Now, please go to:

Start –> Run

In the box type in services.msc then hit < Enter > (or click OK)

In the Name column look for:

Windows Log

< Double-click > it.

In the dialogue box that pops up, check in the Path to executable box.

It should say: C:\WINNT\system32\nvsvcd.exe

That's how to be sure you have the right one.

Now, click Stop to stop that rogue process.

In the Startup type box, change it to Disabled.

Click Apply then OK

Close the services.msc window.

Reboot in "safe" mode.

Double-click ATF-Cleaner.exe to run the program.
Under Main choose: Select All.
Click the Empty Selected button.
Close the program.

Delete all of the following noted (in red) file(s)/FOLDER(s) you can find:

c:\winnt\system32\nvsvcd.exe <— file

c:\winnt\system\smss.exe <— file
(WARNING!!! DELETE THIS SMSS.EXE IN THIS FOLDER ONLY!!!!)

The smss.exe in the system32 folder is the "legitimate" one. LEAVE IT ALONE.

Some malware files may be "hidden".
Be sure to show hidden files when looking for these file(s) and/or folder(s).

Reboot in normal mode and "copy/paste" a new HijackThis! log file into this thread. :)

Many thanks for the quick reply. Lovely clear instructions too!

I have followed them exactly - Slight difference found in that nvsvcd.exe was already marked as disabled - so I made no changes to that process.

Here is my new HJT log -
