Here is the procedure for NOD32 Antivirus. It should work for Smart Security too. 1. If you have an existing NOD32 installation with your login and password for updates you need to export your settings (setup-imort/export settings) 2. The result should be an XML file, rename it to cfg.xml 3. Download MSI instalation file from ESET webpage, rename it to nod32.msi 4. Using 7zip pack these 2 files together, the result should be nod32.7z 5. Download the attachment of this post - config.txt 6. Download this file - 7zS.sfx 7. Now you should have 3 files in 1 directory nod32.7z config.txt and 7zS.sfx 8. Open comand prompt in that directory and type "copy /b 7zS.sfx + config.txt + nod32.7z NOD32.exe" 9. It will create NOD32.exe - your switchless installer 10. Follow the link in previous post to make an addon. Your entries file should look something like this: [general] builddate=12.04.2010 description=Antivirus and antispyware protection language=English title=ESET NOD32 Antivirus Business Edition version=4.2.40 website=http://www.eset.sk/ [EditFile] I386\SVCPACK.INF,SetupHotfixesToRun,AddProgram [AddProgram] NOD32.exe config.txt
