do I have a virus ,trojan or what?

Hi Guys
Im running a p4 with xpsp1 also running Nortons Anti virus2005 and Nortons
Firewall 2005 which have just been put on also adware and spybot as well.
Now the problem Im having is that nearly every time I turn on the pc I keep
getting a (suppose i call it a flash screen ) and looks identicle to the
opening screen of a program called "Mirc" As my pc has been formatted
recently this program hasnt been loaded at all. I have a feeling that its
some sort of virus or trojan as it doesnt do what Mirc would do but Nortons
doesnt pick up on it. Were do I go from here in stopping it.
Has anyone heard of someone having this problem at all.
Thx guys
Cheers

Sorry guys I forgot to mention that it always appears on start up as well.
Thx
