workbook! Is it a virus?!? When i open a microsoft excel workbook, it auto opens 255 worksheet. Even after I adjusted the settings to 3 worksheets, after i close the workbook, the same thing happens again the next time i launch excel. There seems to be hidden macros running, and when i go to program files\microsoft office\office11\xlstart, i will find this book.xlt file in the folder. Even after i delete it, it will appear again the next time i launch excel. Gosh. Can anyone help? is this a virus?

I had a look at Excel for this problem and cannot find anything.

Do an online virus check at this URL:

Then download this, update and run it.

These should clear any visus you may have.

it may be a virus, or just a problem with Excel. i'd suggest doing a system restore to before you started having those problems. system restore is in program files
