two instances of Windows Explorer

[Dgfilm]

Hello,

I'm using Vista Home Premium and in Task Manager it shows (everytime!) that
I have two instances of Windows Exporer running... Can someone please explain
this to me?

Even if I reboot and don't open anything it won't change it. The only things
I have running besides the usual hardware stuff (bluetooth, daemon tools,
sound icon) Sidebar (sometimes) and Pc-Cillin.

Even if I try to run more than one instance of Explorer, by typing explorer
in a run command, I only see one instance in task manager.
Click on one of the instances in the task list and select open file
location.
Then do the same for the other instance and see if it opens in the same file
location.
Maybe you have a virus?
