Windows 95 Software Firewall

[sgs]

Need security software (re DSL connection) on my old PC (Win 95) and new PC (at
various times will run XP, 2000, Linux). Found Avast A-V freeware that works in
Win 95, so should also work on new PC. ZoneAlarm firewall freeware handles new
PC, but not Win 95. Need:

1. Firewall software (freeware ?) for Win 95.
2. Adware, Spyware, PopUp blocking for Win 95 + new PC.
3. Insights into special handling that Linux will require.

Request insights, software/freeware recommendations + url-s. Thanks

Spend $50 and get a real hardware router/firewall that works fine with all OSs.

I like the Linksys.
