I've owned a 2010 13" Macbook for a little over a year and throughout that time have often downloaded files from sites like MediaFire and RapidShare without any problems. However in the past few months, initiating downloads from these sites has triggered a seemingly increasing number of kernel panics.

The last report is posted below. As you can see it blames kernel_task for a page fault which I understand is a somewhat notorious issue - kernel_task eating up virtual memory leading to page faults and panics - so I have a general idea of what is going on.

Unfortunately I am not really sure how to handle this on my own. Does anyone have any advice?

I would guess that it is related to Symantec since it looks like that is the kernel extension that crashed. I would try uninstalling and reinstalling Symantec.
