Remove _http_://ftp2.uk.FreeBSD.org from the mirror list as it has
persistent malware on it and it harms the freebsd.org domain reputation.
I'm leaving the ftp link, it's the sourceforge mirror via http that
seems to be causing the problems.

There's more malware on other shared mirrors than this one, but google
safesearch has been complaining about this one for a long time.

Remove _http_://ftp3.ie.freebsd.org (leaving ftp://).  This is another
shared mirror that is causing windows malware for sourceforge binary
downloads to be attributed to freebsd.org.
