I tried using Norton in my system. Working fine until recently (Norton 2005 before)...

I used to think that Norton is a bad memory eater but to be honest, with 1GB of ram or more, it isnt really noticeable to me. But bad things happened when i tried to update to Norton 2007 (instead of Norton 360). To my surprise, Norton 2007 is not sucking my memory but my CPU speed. After installing the AV, my CPU speed/performance is at a constant 50% even on idle.

After thorough checking, i knew that it is the Norton that is causing the trouble. I uninstall it and keep on with my 2005.

Used AVG before - Gave up after that. Detect unnecessary problems, give away dangerous ones.

Used McAfee before - Gave up as well. Dont like it (for unknown reasons).


For now, i only like NOD32, AntiVir, Norton. These are the ones i trust as off now without giving me any trouble thus far except for Norton 2007.
