vista problems

[tonymon]

ok, when i turned my comp on last night, it loaded up, but an error window opened, saying C:\Users\Ant\AppData\Local\Temp\qommkiij.dll failed to open. and now eveytime i try to open any documents page eg music, my computer or even control panel the computer jibbs itself and the bar at the bottom of the screen disappears, and the page closes. its done this now when i opened the internet page, but had to do it via msn messenger because it doesnt open on the shortcuts on the desktop. i have half a mind to take it to pc world because its still within the year warranty which i think i get. all these pages open fine in safe mode too. ive done a comprehensive scan on norton and it didnt find anything.

any ideas?
