I have been noticing that my Sygate firewall has been blocking some strange things from accessing the internet, and I would like to know if it is normal or something is wrong.

Every time I start the computer, I get a message saying that the file C:\windows\explorer.exe has been blocked. It never seems to try again - it only happens at startup.

I am also seeing the "Win32 Kernel Core Component" C:\windows\system\kernel32.dll trying to access the internet occaisonally.

I already ran a virus check, a trojan check, and adaware (which did find some stuff). Since then, I have not seen the Kernel try and access the internet (could be coincidence) but explorer still does.
