It seems to me like you did all the testing you need to and that the problem is F-Secure. Why not give them a call and ask support what's going on since it's prohibiting the execution of one of your executables? Beyond that, I work with anti-virus software - there has to be a way to exclude directories from their (apparent) on-access scanner. Try excluding the c:\php folder (or wherever you installed PHP). On various platforms, AV on-access scanning can cause various programs to have problems where you need to exclude them from that scanning. If F-Secure doesn't allow you to add an exclude list, then you might be SOL - which would also indicate the quality of the product.

Windows XP-SP1, PHP 4.3.4 or 5.0.0b3,F-Secure Antivirus 5.41 When running the simpliest script from documentation in Windows COMMAND prompt, window hangs. Ctrl+C doesn't help. Window has to be killed. I also found this: F-Secure Active, PHP run from local drive (C:\PHP) - Hangs F-Secure Active, PHP run on network (F:\PHP) - Hangs F-Secure Disabled, PHP run from local drive (C:\PHP) - Hangs F-Secure Disabled, PHP run on network (F:\PHP) - OK I have no problems running on Windows 2000, with F-Secure enabled. This realy is a bad start with PHP for me.
