Pubblicità indesiderate, help

[toscano72]

Buongiorno gente, spero che qualcuno possa aiutarmi.

Ho un pc di un paio di annetti, un Intel P2 Dual core 2600ghz, con XP e Firefox 3.0.1.0 come browser predefinito.

Da qualche giorno ho notato un rallentamento in certi momenti della navigazione e da ieri mi si aprono anche delle pagine web (come nuove pagine) di pubblicità.
La cosa non è pericolosa a quanto sembra, ma fastidiosa. Come antivirus ho Avira Premium, come antispyware Ad-Aware free e A-Squadred Free.

Vi posto subito il log di hijackthis:
