A quick google search shows that it's the user agent for the ask.com toolbar.

	Ah, I'd been googling "AskTbTRL" which revealed nothing. Adding "2" to the end did the trick. Thanks – mcqwerty Nov 19 '11 at 16:13
	I didn't add the two to the end and I still gt the correct result. You should try actually clicking on some of the results next time. – MarkM Nov 19 '11 at 16:50
	And you should try looking up the word "nothing". Google gives different results to different users. In my case, there were zero results returned. Thanks anyway for the pro-tip. – mcqwerty Jan 16 '12 at 19:22
