Is McAfee really any better than Norton?

Up until April this year I was using Norton, but got disillusioned with the product and the performace sapping affect it was having upon my PC. The dreaded 100% CPU usage problem was the final straw. Norton Support Number didnt offer a solution and the internet was full of people afflicted with the same symptoms So I cancelled my subscription to Norton after 3 years of on/off performance related issues and took up McAfee instead. Initially it seemed to be better but in the last 5 or 6 weeks I've been noticing odd things happening. Things such as PC failing to boot up, getting stuck at the logon screen, icons being refreshed at a rate of 1 per every 3 seconds, web pages taking 20 sec to load. Seemingly fine one day but absolutely lousy performance the next - in short an exasperating technical experience. And to cap it all cpu usage roaring away at 100% for no apparent reason even when there are no windows open Even in the dark days of Norton I never experienced anything like this. Have McAfee released a duff update? It was certainly never like this at the start of April In it's present state my laptop is almost rendered unift for use. And yes I have scanned my laptop for virus - it is clean and always has been. Is this a case of the prevention being almost as bad as the disease?
