Worm.Downadup (Conficker) on my MAC

Hopefull someone out there has some insight on how to handle this since my Norton software isn't even detecting it.

 

I ran a copy of ClamXav and it detected 'worm.downadup-9' infection on the 'quarantinefile.qtn' which is part of my norton anti-virus software.

 

Can I simply delete this or will it mess up my Norton software from running properly?

 

Everything I have googled about this worm says it a variation on the 'Conficker' worm and can only be found on Windows machines.

 

If so, why is it coming up on my Mac?

 

Help!!!!!
