Not sure what security package Telus is rebranding. As an aside, Shaw's is F-Secure which is a pretty well respected security suite. If Telus is rebranding a similar grade product, I wouldn't call it garbage.
On the free side, I would take a look at Microsoft's new Security Essentials. It is has an extremely small footprint, does not seem to have any system performance impact, and the beta drew rave reviews from some fairly well respected places. Comodo is excellent, but use the advanced setup, not the basic.
