I didnt know Clam AV had a Windows version of course it might not be the same as I am thinking of, if it is it would be a good choice. The Clam I am thinking of is used on Unix systems wonder if it is the same.
Not sure, he just recommended searching for ClamWin.
Found it using Google. I wonder if it is someway tied together?
ClamWin Free Antivirus is based on ClamAV engine and uses GNU General Public License by the Free Software Foundation, and is free (as in freedom) software.
Yep it is. From the site I linked.
