i again am getting weird 'trojan horse blocked' warnings, while at facebook. i was uploading some photos i took, & at the one point i was simply typing info about one of them when a warning came up; the other time, i had just cancelled out of the upload window when i got the alert.
to me, they're absolutely false positives, as they make no sense whatsoever. i wasn't anywhere - i wasn't redirected or anything of the sort.
(the only other thing i can think is that avast is running into some weird thing with TMN - TrackMeNot)
