Ca Antivirus/Firewall

I installed the CA Antivirus firewall on the parents-in-law computer. The firewall is almost identical to zonealarm. I've not used zonealarm for several months/years now so I can't tell if it is the same as the newer versions, but all the popup dialog boxes and the traffic meters in the taskbar are practically identical. The Antivirus is different and also includes spyware and popup blockers so it will be interesting to see how good they are - i'm sure I'll have plenty of practise as I've already removed lop from the computer twice, amongst many other spyware infections on it. I've also installed SpywareGuard which aims to stop the driveby installations (and i've also installed firebird for my own surfing)
