There is such a thing as searching the internet. I recommend only avast! Antivirus.
You know, I've tried many. It's the best.
And look for ZoneAlarm. It's a decent firewall.
P/S And as for free ones, only AVP. But it's pretty bad. What you see is what you get.
P/S#2) Major Whirlwind, hello. I agree with your opinion about (Kaspersky - a paranoid), 100%. People, spring is here, everyone go outside!;)
