I am in the process of creating a web-based mail-checking system with PHP. This script is stored on my (Windows XP + Apache2 + PHP4) localhost computer. Now, when I run the script and it reads mail, NAV kicks in and scans the message. Normally I wouldn't mind, but this is webbased, I can't get any viruses through this, right? How can I prevent NAV (2003) from kicking in when I am receiving mail with my script. If you want to view the script, please ask.
