I've experienced a problem with my mac constantly uploading data (my monthly internet upload quota was exceeded). My mac runs NIS 5 & being suspicious of malware I run a full system scan with no issues identified. To help me determine what was uploading data, I bought a program “Little Snitch”. To my amazement the application is “symdeepsight-extractor” which is uploading data to the server “upload3.symantec.com” I find it hard to believe that it was necessary for Symantec to collect 1.7Gig of data from my mac. Has anyone else had this issue? Does Symantec have a comment on what data they are collecting off my system? I have now used Little Snitch to block this traffic.
