I recently installed Ubuntu 12.10. I use Clamav and have scanned my system regularly for infections. Today it picked up a potential threat /usr/lib/ruby/1.9.1/rdoc/generator/template/darkfish/js/thickbox-compressed.js. Ubuntu is my only operating system installed. Clamav was not able to delete or quarantine the file. Should i be concerned or is this a false positive? I have scanned the same file multiple times and it picks it up as a threat each time. Also i tried googling the issue before posting and found no information.
A point I forgot to mention, clamav picks it up as PUA.script.packed-1
