Vlk,
First, thanks for your prompt reply :slight_smile:

The error happens only at boot-time. I used to scan by tasks (Enhanced User Interface).
I did boot-time scan only twice; today and on 21/05/2004.
And in both scans I got the above error (and Number of infected files: 0).

My laptop is from Toshiba: Satellite 5105-S607.
So I have no idea how its hard disk ‘TOSHIBA MK4019GAX’ is connected.
Is there a way to know it?

Oh… I forgot to say that I run XP home, and lately I upgraded SP1 to SP2.
