Log inutile, hijack non è compatibile con sistemi a 64 bit

Non solo hai installato Win7 che richiede almeno 1 Gb di memoria RAM solo per avviarsi, ma hai usato anche una versione a 64 bit, reinstalla XP che richiede meno risorse di sistema, oppure aumenta la memoria RAM almeno a 2 Gb, oppure passa a un sistema operativo Linux.

Due antivirus non rallentano il sistema, casomai vanno in conflitto, ma di solito l'ultimo installato disattiva quello precedente.

Ho consigliato anche la distro linux, non hai letto?

Vi ringrazio, provvederò con >>>Xp anche se utilizzo anche Linux
