Till the end of last year I was using Zone Alarm and AVG, but the latest AVG version caused all kinds of trouble with W98.
Thinking a firewall incompatibility might be the problem, I switched from ZA to Kerio but their latest version seems to cause freezing/crashes with W98 too, so then to Sygate but problems seemed to remain, so finally dropped AVG for Avast! which so far looks pretty good.
However this proxy issue seems to call for yet another firewall change (getting tired of all this "system" stuff

)
So- back to Zone Alarm or try Outpost?
(oldish computer- 192MB/266MHz W98)
Any advice much appreciated.
