Suddenly every site I access through Firefox is flagged malicious by f-secure. This includes the BBC, the London Independent, the London Guardian, and various other sites. What's happening? Doesn't seem to happen with Microsoft Explorer.
Now it's happening with Internet Explorer btoo, but not quite so much as with Firefox.
This is the blurb accompanying the warning:

Reinstalled F-Secure and the problem has gone away. Weird.
