After vowing never to put Symantec anything on my computer ever again, I installed the 90 trial version of Norton AV 2005. Just the AV, nothing else. I am surprised. It seems pretty light on my computer. Not much slowdown at all. I can run any program I want and the delay in loading is minimal. This is a big surprise to me, considering how miserably slow everything was 3 or 4 years ago -- the last time I tried Norton. Installation was easy and update not a problem, although slow since we only have dialup here in the sticks. The scan is going as I type this and I noticed very little slow down while connecting to the net and opening my browser. I also have MS Word running, along with another program. So far, I have no complaints -- except for the price should I want to keep it after the trial. I think, though, I could find it at Best Buy or other places quite a bit cheaper than what Symantec wants for it. I've only had it installed for barely a half an hour, so probably shouldn't be praising it yet.
