The following tutorial is only for NOD32 v3 (version 3.x) users.
Background:
It is always a good practice to scan files that are transferred via instant messaging applications, such as Windows Live Messenger. Moreover Windows Live Messenger is “demanding” to associate an antivirus software in order to scan files of certain “dangerous” types (*.exe, *.zip etc.).
Here is how you can configure Windows Live Messenger to use NOD32 for scanning file transfers.
Method 1 – quickly scan file and don’t read the result
1. Navigate to C:/Program Files/ folder and take a note of your NOD32 installation folder.
2. On Windows Live Messenger go to -> (Menu/Show Menu) Tools -> Options… -> File Transfer
3. Place a tick on the “Scan files for viruses using :” checkbox
4. Click on the input textbox below, clear it, and paste the following line:
“C:\Program Files\NOD32\ecls.exe” /base-dir=”C:\Program Files\NOD32″ /log-all /aind /no-boots /adware /sfx /unsafe /unwanted /heur /adv-heur /action=clean
Replace “C:\Program Files\NOD32″ with the path from step 1.
5. Click on Apply/OK, this is it!
Method 2 – quickly scan file and read the output result
1. Navigate to C:/Program Files/ folder and take a note of your NOD32 installation folder.
2. Inside the NOD32 installation folder, create a new text document.
3. Open it with notepad and paste the following three lines:
@echo off
“C:\Program Files\NOD32\ecls.exe” /base-dir=”C:\Program Files\NOD32″ /log-all /aind /no-boots /adware /sfx /unsafe /unwanted /heur /adv-heur /action=clean %1
pause
Replace “C:\Program Files\NOD32″ with the path from step 1.
4. Rename your text file to “scan.cmd” (remove the txt extension!).
5. On Windows Live Messenger go to -> (Menu.Show Menu) Tools -> Options… -> File Transfer
6. Place a tick on the “Scan files for viruses using :” checkbox
7. Click on the input textbox below, clear it, and paste the following line:
“C:\Program Files\NOD32\scan.cmd”
Again replace “C:\Program Files\NOD32″ with the path from step 1.
8. Click on Apply/OK, this is it!

This does not work for my version (3.0.621.0).
The way to do it is described here: http://training.eset.com/kb/index.php?option=com_kb&Itemid=29&page=articles&articleid=549
Confirmed working. I guess you may pause that operation and show the results somehow, but I don’t bother.
The above command lines are working but it’s missing the %1 at the end.
You should read:
“C:\Program Files\NOD32\ecls.exe” /base-dir=”C:\Program Files\NOD32″ /log-all /aind /no-boots /adware /sfx /unsafe /unwanted /heur /adv-heur /action=clean %1
on one single line. You should also be carefull when you cut and past the command from “decoding” as it contains non-UNICODE’s characters.
