I make a slideshow but then delete it. i delete it from all places in my pc.
but when i open MS ppt. it still shows up as still there. when i click to
open it even though i don't want it my pc goes into a visrus scan and then
freezes. how do i get it off my powerpoint file list?

Straight from the help file:

Show, hide, or change the list of recently used presentations
The list of most recently used presentations appears at the bottom of the
File menu and at the top of the New Presentation task pane (File menu, New
command).
On the Tools menu, click Options, and then click the General tab.
Under General Options, do one of the following:
To display or hide the list, select or clear the Recently used file list
check box.
To change the number of presentation files that you want displayed, click
the arrows to select a number.
Note The setting you select applies to Microsoft PowerPoint but not to any
other Office programs.
