It's set to reopen apps and such at startup.
As to the 4 blank pages, if you start a new word document and it has more than one blank page here's a google about the normal.dot file. Please folk, I can't guess which of the dozen Word versions you have.
When I start my laptop it will open Word with 4 blank pages. Sometimes it will open Google and Word, or Excel. Does this mean it has a virus? I have Avast and it is up to date but it is the free version. Or, is there something else wrong?
