Started up my computer this afternoon and noticed that the Symantec icon had disappeared from the system tray (the 'toolbar' at the bottom of the screen, I think) I've used their free firewall for a couple of years now and so far, not had any problems, or at least, (being a non-techie), don't think I have! When searching the net later, I found that Symantec have discontinued this free firewall due to a company amalgamation, or takeover. Question (1) Can this cause it to disappear from my tray or has something gone awry with my computer? And question (2) If I can't get a free version of this any more, what other reliable freebies are available?
What would Catters recommend/advise. I'm still in the last century 'cos I'm running Windows '98 and, so far it seems to be all I need.
However, any advice greatly appreciated.

Regards

Andy
