Just tell your antivirus program to ignore the folder /Users/username/Library/Application Support/Bitcoin
This is a huge mistake!
Just imagine: a unknown virus download some viruses to this directory. The folder is ignore by the virus scanner, so _valid_ viruses are not recognized, they can do whatever they want to do.

A valid concern, although if a virus is writing to your system, you've already caught it.
A better solution is to set your scanner to ignore sst files, which are not executable and cannot catch a virus. Setting a virus scanner to scan all files is a recipe for a variety of problems including corrupted files/downloads, blocked programs, and significantly reduced performance. You may wish to set it to scan executable/scriptables only.
