Hey all. I have a laptop with these specs: Pentium 1 133mhz (non mmx) 64 mbs ram 1.3 gbs HD I am running TinyXP Beast Edition. So it takes a lot of resources already. I use it to access internet using several wireless networks in my town. Most are unsecured, so I need to have good security software. It cannot be heavy on resources though... Right now I am using ThreatFire as antivirus (it's VERY light on resources and doesn't need regular updates as others). As for the Firewall I was going to use PC Tools Firewall, but it's too heavy... It's one of the lightest firewalls on the net and still it's too heavy to use! So I decided do think about it. I need a firewall that will: Make my internet browsing safe (stops people from "sniffing" the wireless conection to steal my data); Prevents atacks from outside; ThreatFire already stops unwanted accesses from the computer to the internet. I thought about using GhostWall but I have no idea how to configure it to meet my needs Also, if there is another firewall that you think it's good, just let me know =) Also, if anyone wants to make use of some old machine, I can give some pointers on what software to choose.
