Hello, All!

I have been using a Macro enabled Excel file (.xlsm) for the calculation of
expenses quite a long time.

Once got a $20 short (difference) in the calculation. Even after checking
again and again did not find the reason for the error.

The next day after entering more expenses in the same file got tallied
automatically. Even the earlier days $20 short cleared this time.

Is it because of some macro viruses? The above happened twice in a month. My
AntiVirus Avast free, Adaware etc. declared no virus.

How to safely use a macro enabled excel file?

Thanks for any replies.

Trish
