Here's how to fix it, go to:

http://www.clamav.net/downloads#otherversions

And download the portable version of ClamAV for both Win32 and Win64:

Before continuing on the next step, I would suggest to backup both bin & bin64 folder:

Extract the both downloaded .zip file, and copy all contents:
clamav-x.xxx.x-win-x86-portable.zip goes to: "C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Clam\bin"
clamav-x.xxx.x-win-x64-portable.zip goes to: "C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Clam\bin64"

Go to the SmarterMail admin console -> Settings -> ClamAV.
Disable the ClamAV, click save, and re-enable it again to make sure that the SmarterMail will load the new ClamAV executables.
Last, but not least, you want to click on the "..." button and click "Update ClamAV Definitions":
