At bootup a blue screen showing the Acronis Logo in the bottom right corner

Hi All, I'm running a REGISTERD copy Acronis 13 home on a Windows XP SP3 Operating system. I have just loaded Spybot Pro and checked the system for everything Spybot can deliver. After making sure the system was clean I switched it off. When I booted it the the next day the screen showed a blue screen with the Acronis logo in the bottom right hand corner. The Acronis logo graphic looks as though it is raised up from the blue background "embossed". I have tried re-booting many times and the blue screen appears as soon as the BIOS screen has finished running.

The blue screen occurs even before the installed F11 Acronis manager gets a chance to activate. THE BLUE SCREEN IS NOT THE NORMAL BLUE SCREEN OF DEATH it is definitely a graphic or the Acronis logo would not be shown as embosed. I can't beleave it's the usual DOS attack.
The only thing I can do is to recover the system using an Acronis boot disk
I would be most grateful for suggestions for a cure.
