Microsoft Exel Files having macro

[abduljabbarpm]

I have installed Avast 5 in my system, and when I am opening an MS Excel files having macros, it displays macros has been disabled since there is no antivirus.

Even though I have installed the latest version of Avast - Avast 5 and Microsoft Office 2007
Pls. let me know how can I solve this problem

I use MS Excel 2007 sheets with macros without problem.
You need to configure MS Office (and not avast) to allow sheets with macros either only that one or any sheet.
Can you post a screenshot of the error you're seeing?
