1. install clamAv virus scanner:
Windows:

• download http://sourceforge.net/projects/clamwin/files/clamwin/0.98.5/clamwin-0.98.5-setup.exe/download
• install with default settings
• after install and database update, copy C:\ProgramData\.clamwin\db directory to C:\Program Files (x86)\ClamWin\bin\
• add C:\Program Files (x86)\ClamWin\bin\ to PATH

(make sure clamscan working fine by checking in terminal: )

clamscan --stdout --no-summary [path to test file]

(You should see output message like clam-output.png)

2. Put these properties into portal-ext.properties file:

dl.store.antivirus.enabled=true 
dl.store.antivirus.impl=com.liferay.portlet.documentlibrary.antivirus.ClamAntivirusScannerImpl

3. Start liferay

4. Log in as Test Test user and go to admin >content > documents and media

5. upload an anti virus test file to Documents and Media, I used eicar.com.txt downloaded from http://www.eicar.org/85-0-Download.html

Expected result: a message on Documents and Media portlet, saying "A virus was detected in the file."

Actual result: "Unable to scan file for viruses." (picture)
