false positive of the day
I am also only an F-Secure user. And my experience, usually, is about home beta F-Secure (so, maybe stable F-Secure or Business F-Secure solutions with another ratings).
Some of false positives (!? likely) from my collection:
Adult category is added to likely unrelated websites (one is bar/pub/restaurant - what is possible to rate as something else rather than adult maybe; especially, when Alcohol-category is introduced; another is someone's Wordpress blog):
**bleep**’s & Cows bar and Mike Adcock blog.
-- F-Secure Community decided to BleepIt bar too.
I also found that F-Secure rating does not like Adcock surname at all. Most of random checks against indexed pages are about someone's website (Alison, Anthony, Bryan, Carolyn, Kathleen, ... Adcock) or some companies as health-care?!/design?!/business?!/..anything - where Adcock is own of owners (or part of company's name). All of them with "Adult content"-category rating.
I do not know what is wrong with them.
// little addition: not all (after today's doublecheck) - but many. while most of them are likely false positive anyway.
