Anyone please help!

I'm surprised earlier when I TRIED opening one of my documents. During my first attempt to open my word document, my AVG free antivirus detected a MALWARE named winword.exe. Of course, I selected the option to remove the detected malware, not realizing that it's the executable file for Microsoft word.

And then, I tried opening my documents again, but this time, a pop-up message is being displayed informing me that I don't have enough privilege accessing the file, and the same warning keeps on popping every time I tried opening a word document. On the other hand, excel, publisher, and other Microsoft programs are working properly,

What happened? what should I do?

I have a Windows XP computer, and the program in question is Microsoft 2007 edition I would suggest running an alternative malware scanner (such as Malware Bytes Antimalware Free) as a one-off to ensure your machine's as clean as possible. After than, re-run the Office setup from CD. It will give you an option to repair your existing installation - choose that.I have Malwarebytes installed but is currently DISABLED. I'm only using it once a month to perform a full scan. I tried running it with HOPE that it will solve my problem with winword.exe, but it detected nothing.

On the other hand, I tried the repair option through the Microsoft Installation Wizard. It TOOK less than a 45 minutes before the repair option finished, but I'm very happy that it solved my problem.

Thanks for the advice...
