You couldn't pay me enough to run Symantec's piece of crap. Give AVG a try; I've got two Vertex drives deployed at work, AVG is on both systems, I haven't had any issues. And despite the apparent assertions of some people in this thread, they have made a significant, tangible positive difference to system speed and responsiveness. If they prove to be reliable, every machine I build from here on out for work will be getting either indilinx-based MLC or good SLC SSDs.
I should note that this was the corp edition so it just sits in the background and is generally unoffensive and does its job this is NOT the consumer version which I also dislike. personally I think AVG is way too ugly (these are design people..) What would you recomend that has had at least a minimum amount of effort spent on it's interface design?
