'Page not found' page hijacked by a virus or worm?
On a Win2K system we recently had the problem that any wrong URL entered at the IE URL prompt leads to some (changing) sex portal, i. e. it comes instead of the 'page not found' page. Symantic Antivirus, Pest Patrol and SpyBot couldn't repair the issue though they seem now to block some of the pages.
We changed to Mozilla Firefox but - wondering - the issue was the same.
