c*** cleaner isntit ?
I can only say, using Opera and / or FireFox browsers SEEMs to attract very few problems ... NortonAV and ZAP (Zone Alarm Pro firewall).
Ok, easy to become paranoid ... If banking / buying / selling online tis all a bit of a concern.
Since installing ZAP and learning via the ZA forum how to configure it, I have gone almost a full year with ZAP and NAV ... No viruses detected, Adaware SE personal ... SBS&D running tea timer etc ... Cr apCleaner ... Swatit ... TDS-3 (anti-trojan) All updated as soon as available and regularly run .. have found nothing !!
All M$ updates are installed as they become available.
I think the M$ updating, ZAP, Opera / Firefox browsing, and opening, in the first instance, mail as text only are the cornerstones of my pleasant experience during the year.
BTW on Win98se, the browsers mentioned install without 'upsetting' IE6 or anything else .. all run happily together,have run all 3 at the same time without problem.
