Sounds like you install of windows has crashed during loadup. The number and symbols you refer to are possibly the standard on screen diagnostics you get when entering safe mode.
What i would do load the laptop back to the menu where is asked you what mode to choose and try 2 things.
1. Last known good configuration
2. Option not to reboot after failure (cant remember the exact wording off hand)
If the 1st one fails (highly possible) then the 2nd one will tell you if its a windows corruption. Should during the 2nd one a blue screen occur take a note of what it says and google it. Usually tells you what the problem is. Common ones are PAGE IN NON PAGE MEMORY - DLL ERROR - IRQ NOT LESS OR EQUAL something along those lines.
If you get an error its not a virus but a corrupt windows install with possible hardware issue. (RAM nearly always).
My gut feeling is its not a virus, but can never rule it out.
Final thing to try. If you have a windows cd, run it and go through install but when it detects previous version of windows select REPAIR. This will fix windows and keep all your documents and settings.
Good Luck
