Problems for getting start working on ClamAV project

I am having below problems for getting start working on ClamAV project.

1:
I have downloaded ClamAV project from below location: 
"git clone git://clamwin.git.sourceforge.net/gitroot/clamwin/clamav-win32.git"

I have build it in Visual Studio 2008. But while running executable it give below errors:

ERROR: Can't open/parse the config file C:\Users\Nilesh.admin-PC\clamav-win32\contrib\msvc\Debug\Win32\clamd.conf

ERROR: Can't open/parse the config file C:\Users\Nilesh.admin-PC\clamav-win32\co
ntrib\msvc\Debug\Win32\freshclam.conf

Loading Clamav DB...
LibClamAV Error: cl_load(): Can't get status of daily.cvd
Error loading daily.cvd...

2.
Usage C:\Users\Nilesh.admin-PC\clamav-win32\contrib\msvc\Debug\Win32\unscrambler.exe scrambled.dmp
What is exactly that "scrambled.dmp" files and their use..?

3.
The file "clamscan.exe" generated after build in Visual Studio. I used that file for scanning some viruses samples.
Result summary  was:
----------- SCAN SUMMARY -----------
Known viruses: 2341759
Engine version: devel@clamwin msvc - Jun 10 2013
Scanned directories: 1
Scanned files: 7
Infected files: 5
Data scanned: 0.50 MB
Data read: 0.45 MB (ratio 1.09:1)
Time: 19.889 sec (0 m 19 s)

But i scanned same samples using "clamscan.exe"  which is generated after installing ClamWin Antivirus it gives scan summary as below:
----------- SCAN SUMMARY -----------
Known viruses: 2341759
Engine version: 0.97.8
Scanned directories: 1
Scanned files: 7
Infected files: 5
Data scanned: 0.50 MB
Data read: 0.45 MB (ratio 1.09:1)
Time: 7.051 sec (0 m 7 s)

There is huge difference in scan time. Why...?
Is ClamAV project at location "git clone git://clamwin.git.sourceforge.net/gitroot/clamwin/clamav-win32.git" is outdated..?
If that so then send me URL to download latest ClamAV project.

3.
I am getting problem to understand the working flow of project. So please help me.


Best Regards,
Nilesh Salunke.
