Plus de mails et de favoris ds Mozilla : infection ? (cf. log HJT)

Bonjour,
A l'ouverture de Mozilla Thunderbird, le soft me demande de créer un compte (???). Bon, je reconfigure : anciens mails disparus. Je checke mon compte sur le webmail de free : vide (hier soir, tout y était encore).
J'ouvre Firefox : tous mes favoris ont disparu !!!
J'ai F-Secure Internet Security 2006 (dc AV + firewall + antispyware etc) qui a l'air de fonctionner normalement.
Qqun trouve-t-il qqchose de louche ds mon log HJT ci-dessous ou toute autre idée (et si possible, retrouver mes mails & favoris ???)
Merci d'avance,
