I got a infected file on May 28th, 2014, which Symantec Endpoint Protection quarantined. I want to delete this infected file from my hard drive. I looked online on how to delete a quarantined file, but I am unable to do it. Firstly, when I go to the quarantine window, there is a lock button at the bottom left corner. When I click it, it does not unlock, so I cannot manage my quarantined files. When I hold the button down, it looks like it is unlocked, but when I let go of the button, it locks itself again. Also, I cannot access the Symantec folder under the Application Support folder because it is not there. Hence, I cannot delete the quarantined file from there either. I was wondering if I need to reinstall Symantec Endpoint Protection on my computer, and if the installation driver that I downloaded will allow me to reinstall the software? Thanks!!

See if this thread provides any insight:

The SEP/SAV for Macintosh quarantine is stored in a single file:

/Library/Application Support/Symantec/Antivirus/QuarantineFile.qtn

How to access the Quarantine folder in Mac OS X?

Thanks so much for the responses. I have consulted the two links and they have given me important insight. My problem, however, is that the Symantec folder is missing from the application support folder. Do I need to reinstall symantec on my computer? I have a copy of the installation driver. Thanks!

If you have the ability to re-install you can try that
