Office 2007 tmp files show up after saving an edited document

Hi All,

Strangest problem I've come across to date :)  User has the following:

Windows XP Pro SP3 all high priority updates applied
Office 2007 Pro all SP and updates applied.

Whenever he opens up an existing Word, Excel or PowerPoint 2007 file, edits it and then saves it, a tmp file (in the format of but different letters all the time -  AEMXEPD.tmp) gets created in the same location, almost the same size as the original file itself.  This happens when he saves as a 2007 doc or even as a 97-2003 doc.  I've verified that this is the case only with existing documents in both Word and PowerPoint.  Couldn't get it to do it in Excel, but he says it's happened and after seeing it for myself I don't doubt him.

Here's the strange part.  I did a clean reinstall of his laptop, OS and Office, applied all updates, gave back his machine and voila it started happening again after he started working on some existing documents that same day.  He says he hasn't installed anything or made any system changes to his machine, but sometimes tryng to figure that out can be half the battle as well ;)

My best guess is it may have something to do with an existing file he may have opened that for some strange reason (could be infected with something) made some changes to how Office saves existing files.

Any help would be appreciated.  Thanks!

Thanks for the input.  Actually figured it out.  It isn't so much an Office 2007 problem but a Trend Micro 2009 problem.  Trend Micro's site has a support issue describing the exact problem with their Trend Micro 2008 version.  Their solution was to reinstall their AV package.  That didn't work here with 2009 even with a fresh install.  Turning off the virus and spyware option made the problem go away but kind of defeats the purpose of having AV software :)

Removed Trend Micro and went with another AV package and problem has been fixed but not solved.  Weird that it would only happen on this persons machine.  All of my other users are set up the same with Office 2007 and Trend Micro 2009 including myself and no one else has run into this problem.

Frustrating but at least we have a partial solution.

Forgot to add:

I took 2 of the powerpoint files that I created on his machine, that were also causing this issue, and opened them up on another machine.  One was in 2007 format and the other was in 97-2003 format.  Opened, edited, saved and no tmp files were created on the other machine.

Sounds like normal Word behavior to me. Word uses temp files extensively. The actual document (.doc) that we think of in a Word document is only the final product of all of these temp files put together. They are hidden temp files, though. So, if you turn off showing hidden files and folders, then they should disappear.

Have a look at this form more info:
I agree with dopyiii. Word will clean up the temp files if it gets closed down properly. If the machine gets powered off or Word abruptly closes, then the temp files are what makeup the AutoRecover process. This is also why it is NOT recommended to work on a Word document (or Excel) directly off of a Jump drive. If the temp file runs out of room to grow, then Word potentially will corrupt the document.

It seems that more and more of my users as they upgrade to TrendMicro Internet Security 2009  are having this same issue, so have started to move to another AV package company wide.
