I wouldn't say it was significantly better than a paid for solution, but it is definitely better than nothing at all. I would just advise that updates can be a little sluggish with the more.. cost effective anti virus solutions. Great for home use though, no frills and does the job.
I use it currently, but thats more down to the fact my Norton subscription has run out and there isn't much point in getting one until I get my new PC next week.
