Symantec had a customer go here to confirm that their antivirus software is working as expected.
Go to the folling website: www.eicar.org.
If the antivirus software is working as expected, you will not be able to download the eicar.com antivirus testfile.
On the main page in the left pane go to "The AntiVirus testfile eicar.com".
Scroll to the bottom of the page the just choose to download the eicar.com file.
Chose to save the file on your desktop.
If your antivirus software is working as expected, you will be blocked from downloading the file and your antivirus software should pop up a warning.
This is a great way to confirm that your antivirus software is working w/o actually testing with true virus.
Thanks Symantec support!
