Linking does not create a .exe for debug

[fsdbass]

I have been using codeblock for a few months, but today It will not create an executable for Debug target.  I am compiling the hello world console application.  When I click on the build button, the bin\Debug\Hw.exe is not created even though there are no error messages. I have codeblocks installed on a Windows 8.1 system.
mingw32-g++.exe -Wall -fexceptions -g -DWINVER=0x0501 -D_WIN32_WINNT=0x0501  -c C:\Users\Franklin\Documents\C++\Hw\main.cpp -o obj\Debug\main.o
mingw32-g++.exe  -o bin\Debug\Hw.exe obj\Debug\main.o   -lwinmm
Process terminated with status 0 (0 minute(s), 1 second(s))
0 error(s), 0 warning(s) (0 minute(s), 1 second(s))
Obviously something has changed, but I have no idea what.

Best guess is a Anti-Virus software caused problem.

Tnx.  The other things I observed make this a good possibility.
