What is "TALagent" and why is it "Exiting out of boredom"?

I'm trying to help a colleague whose MacBook periodically switches off without warning (I've had similar problems on a Mac Mini, so it's not power related). While investigating the logs in Library/Logs, I found a file talagent.log with something very odd, last updated very close to the time the computer last switched off without warning: Time Bundle ID Status Comment 0.000 - - TALagent Started (system uptime: 238.18 sec) 0.007 - - Liveness: 0 -> 1 (run_as_server) 0.038 - - Successfully read encryption key from keychain in 0.030809 seconds 15.007 - - Liveness: 1 -> 0 (__run_as_server_block_invoke) 15.007 - - Exiting out of boredom What the heck is talagent and what does it mean that it is **"Exiting out of boredom"**? I've read this thread but it doesn't help me understand what's going on here. My first thought was that it must be a virus, because that's such a non-professional thing for a log entry to say, but that linked thread seems to imply it's not such a concern; but it doesn't help me understand what it is or what that means. We use Symantec as a virus scanner, and the Mac in question is on Mavericks (can't currently update for unrelated compatibility reasons).
