I have an ASUS A7V with Athlon 1Ghz ,128 MB memory , ATX Midi case 300 W and 4 yrs old ,Win '98 SE . Am currently using Norton Internet Security and an ADSL 750 kbps connected via modem/router to an network interface card on the PC . The Norton Internet Security slows the system down somewhat . Was considering changing to Zone Alarm Security Suite . Would this be any better/worse than the Norton Internet Security re system slow down ? Any other cons/pros ?
If you have a router don't bother with either of them, you dont need them. The router acts as a barrier between you and the internet so you don't have to worry about putting firewall software on your computer.
Not having either of them would definatly speed up your computer
If you are ultra paranoid or something buy a better router that has true hardware firewall functions. It will cost as much as a licence from either norton or zone alarm and will be much better.
