Ciao ragazzi ho sempre lo stesso problema di qualche giorno fa.
Ho delle finestre che non posso chiudere sullo schermo che non mi permettono a volte di lavorare in quanto stanno proprio nel mezzo dello schermo.
Ho fatto uno scan con HijackThis v2.0.4, ecco qua: Grazie mille ancora :)

Giulia il log ti conviene metterlo nella sezione Sicurezza virus io non sono un esperto in questo campo ma vedo che hai molte toolbar e programmi inutili che si avviano in automatico.
Mentre aspetti il parere di qualche esperto del settore fai un pò di pulizie.Scarica AdwCleaner lancialo e clicca su Elimina dai l'ok quando ti viene richiesto e se alla fine chiede il riavvio riavvia.
Fai una scansione completa con Malwarebytes aggiornato ed elimina cio che trova,alla fine come AdwCleaner ti rilascerà un log,carica tutti e tre i log su Wikysend( http://www.wikisend.com/ )e metti gli indirizzi per visionarli(questo per non avere post chilometrici)nella sezione Sicurezza come ti ho detto sopra specificando il tuo problema.
P.S.Alla fine delle scansioni dai una ripulita con CCleaner a files e rigistro.
Ciao.
