Random Excel file when updating links

[Bluequeen]

I have quite a few presentations that I use that are linked up with Excel files. However in the past week or so I have started to get a random 'Microsoft Excel' file pop up in the task manager, when the file pops up it stalls the links from updating however as soon as end it the links go back to updating, it continues to pop up the whole time and I just keep ending it.

Also if I'm in the powerpoint slide and trying to adjust the data on a graph when I go to edit data I get the same pop up in task manager and I have to end it before it will allow me to actually view the excel file I need.

I have run scans on both of my security programs and it's not a virus.



Any ideas??
