Hi SpyDie, sorry for not getting back to you earlier. I have fixed those entries with HijackThis but can't do the online scan because my connection (56k) only works for about half an hour before I start getting cannot find server/page not found errors. I have noticed that sometimes when this half hour is up, the tool bar flickers briefly into what looks like safe mode before flicking back into normal mode. After this, I can't use any of the buttons on the toolbar, including the volume control for the speakers (I get a 'drivers not installed' message or something to that effect).
