Dear Experts

Sometimes when I run My.exe, it shows following error message

"File my.exe is not object file"

I have reached on this point that this is the result of virus attack on my.exe.

So I run Norton Antivirus 2003 or Pc-Cillin 2002. After cleaning viruses when I run my.exe again, it show another dialouge box as

Do program   :
Files of type   : program (*.fxp)

May it requires any fxp file. Then I have to create my.exe agian.
I think this is not a good solution because endusers pc has only tables and exe and to create exe again there is need of source codes.

Is there anyother solution, inwhich enduser may correct this problem hiself.
Or how to avoid by this problem.

Please help
