Last night I got home and activated the screen(from power saver), and found a screen full of popups, IE had not been open before.
When I got these closed, open IE and found it had totally changed. Lycos side search, Google toolbar gone, home page changed. Tryed SpyBot, found MANY adware entries, choose FIX PROBLEMS, all but BACK-WEB-LITE removed. After a restart all cleared. Now NO WEB pages, message asking to check network setting. Can access web via Windows Explorer and Mozilla.
Tryed reinstalling Windows XP PRO and later IE6, no help. Tryed a full (up-to-date) Norton Virus system scan, none found. Also ZoneAlarm Pro is in use, problem still there with ZAP shutdown.
