HeHe, I've always been a little paranoid about getting a virus on my machine. I mentioned in another thread that I had never had a virus. I was wrong, I got one and it was running an up-to-date copy of NAV.
I've tried them all and two of the most popular are at the bottom of my list, Norton and McAfee. I've had nothing but trouble with lockups and resources with those two.
eTrust is a little overkill actually, but as you know, one can't be too sure.
