Tutti abbiamo system, è uno dei principali processi di windows.

Da un po' di tempo ho individuato nel task manager un processo System che mi occupa molta memoria, visto che prima nn c'era penso sia un virus.

Se vuoi fare pulizia ed avere un pc più performante inizierei a togliere avg, non so se stavi facendo qualcosa di particolare ma 11 processi attivi mi sembrano troppi. Poi avg 10 è pure una versione vecchi mi sembra.
C:\PROGRA~1\AVG\AVG10\avgchsvx.exe
C:\Programmi\AVG\AVG10\avgtray.exe
C:\Programmi\AVG\AVG10\Identity Protection\agent\bin\avgidsmonitor.exe
C:\Programmi\AVG\AVG10\avgfws.exe
C:\Programmi\AVG\AVG10\avgwdsvc.exe
C:\Programmi\AVG\AVG10\avgam.exe
C:\Programmi\AVG\AVG10\avgnsx.exe
C:\Programmi\AVG\AVG10\Identity Protection\Agent\Bin\AVGIDSAgent.exe
C:\Programmi\AVG\AVG10\avgcsrvx.exe
C:\PROGRA~1\AVG\AVG10\avgrsx.exe
C:\Programmi\AVG\AVG10\avgcsrvx.exe

Altro mattoncino da eliminare è adware
O23 - Service: Lavasoft Ad-Aware Service - Lavasoft - C:\Programmi\Lavasoft\Ad-Aware\AAWService.exe
Scarso come programma è pesante.

Anche questi li puoi eliminare dall'avvio anche se il guadagno non è poi eccessivo.
O4 - HKLM\..\Run: [Adobe Reader Speed Launcher] "C:\Programmi\Adobe\Reader 8.0\Reader\Reader_sl.exe"
O4 - HKLM\..\Run: [Adobe ARM] "C:\Programmi\File comuni\Adobe\ARM\1.0\AdobeARM.exe"
O4 - HKLM\..\Run: [QuickTime Task] "C:\Programmi\QuickTime\QTTask.exe" -atboottime
O4 - HKLM\..\Run: [iTunesHelper] "C:\Programmi\iTunes\iTunesHelper.exe"

Altre cose da pulire sono le toolbar, in particolare quella di google a meno che tu non la usi per scopi particolari.

quoto crazy.cat se volessi mantenete avg come antivirus passa alla versione 2012 più leggere ed efficiente rispetto al passato

Anzitutto è necessaria anche una schermata del Task Manager ... in tal proposito non è detto che a parità di memoria si debba avere chissà quanti e quali virus ... l'unico modo per saperlo è quello di controllare con tool specifici a seconda dei casi ... come suggerito e come ho avuto l'immenso piacere scorrendo il tuo log di hijackthis , hai un sacco di programmi TSR , troppi , da motorola a bonjour per non parlare della toolbar di utorrent ... se vuoi cercare dei torrent scaricati BIT CHE , un motore di ricerca stand-alone che puoi consultare tranquillamente dal desktop anzichè andare ad appesantire IE oppure Mozilla tramite toolbar .
Vediamo quindi prima la schermata del tuo task manager in cosa consiste e poi passiamo alla controffensiva ok ?

Per controllare il log di Hijackthis vai a questo indirizzo : http://www.hijackthis.de/it

1- copia ed incolla tutto il contenuto del file di log
2- scegli il file di log dal pc

Ci sono alcune cose che in effetti lasciano pensare ad una probabile infezione ma è presto per dirlo non voglio sbilanciarmi.
