Glad you asked this, I'm curious as well.I have McAfee right now but thinking about using Kasperkey free version, is it a better anti virus program?
We use Microsoft Security Essentials here at home.
Years ago, we used a higher tier version of Norton.
Where I work, they use McAfee, and I haven't been impressed (at all), at least not for what it charges, and for what seems to slip through, but in all fairness, it's no telling what some are clicking on/opening.
