grazie.

Certo che è lento se usi AVG 2012 e Comodo Firewall ... peraltro ti consiglio di passare a Chrome al posto di IE 7 ... se clicchi su START - ESEGUI - e scrivi msconfig e dai invio vedrai nella scheda AVVIO tutti i programmi che partono e rimangono in memoria ... dal log che hai postato qui sono un'enormità ... insomma cerca di ottimizzare il software in dotazione escludendo parti non necessarie quali google update , CD Burner e cosi' via sono troppi e tutti in memoria ... AVG consuma un botto di memoria ... ci sono circa 6-7 processi solo di AVG ... e poi detto tra noi non è il migliore eh ... ti consiglio comunque per sicurezza di fare una scansione con ComboFix che trovi a questo indirizzo : http://www.bleepingcomputer.com/download/combofix/ .

Disattiva temporeanamente AVG
Cliccaci 2 volte col tasto sinistro del mouse
Una volta partito ti chiederà d'installare la console di ripristino - ignoralo
fallo continuare ed ignora tutti i messaggi
finiti i 50 passaggi (steps) creerà un report

SE ci sono virus vedrai delle scritte nel report "voci ELIMINATE o ELIMINAZIONE" ... tranquillo ha fatto il suo sporco lavoro !!
Il sistema adesso è a posto ... riavvialo e nota la differenza !!
