I recently change to ESET’s NOD32 for my virus scanner and realized that I hadn’t set my Windows Live Messenger to use it to scan received files. I found this helpful posting that describes the necessary steps: http://www.wilderssecurity.com/showthread.php?p=910390 And those steps are:
1. Login to Messenger.
2. Click on Tools.
3. Click on Options.
4. Click on “File Transfer”.
5. Place a tick in “Scan files for viruses using:”.
6. Paste the following (including the quotation marks):
“C:\Program Files\Eset\nod32.exe” /selfcheck+ /list+ /scroll+ /quit+ /pattern+ /heur+ /scanfile+ /scanboot- /scanmbr- /scanmem- /arch+ /sfx+ /pack+ /mailbox- /adware /unsafe /ah /prompt /all
7. Click on “Apply”.
8. Click on “OK”.
