I have Microsoft Security Essentials and Spybot Search and Destroy on my computer already, and Windows is set to automatically downloads updates. I'm currently having MSSE and Spybot S&D do full scans.
This morning when I started up, after the Dell startup screen, but before the Windows startup screen, the screen turned black and in the corner was a small logo and the word (I think) "Pheonix". It was only up for half a second, but I've never seen that screen before.
If it is a rootkit, it's pretty dumb of them to display something onscreen during startup. 
If it's not a rootkit, how come I've never seen it before until this morning? I've booted up my computer loads of times in the past, and have several times went into the bios or safe mode, and I've never saw that screen before.
Usually, I just turn on my computer and walk away for about a minute so Windows can start up, so that might explain missing that screen some of the time, but perhaps not all the time.
How can I check if something's on here? Can I see it in the BIOS somehow? What do you think it was?
