Last week, I began having problems with viewing PDF files and website
animations in Internet Explorer. Something new that I noticed was that there
are four password-protected VBA projects (pdfmaker.xla, funcres.xla,
html.xla, and atpvbaen.xla) in my Excel VB editor.

I don't know how to remove them and don't know how they got there because
I'd never seen them before last week. I do know that I swapped files with a
co-worker last week and the problems began soon after.

Do you know how I can remove these password-protected projects and if this
is the cause of my Internet Explorer PDF issues?

Thanks.
