Ho il computer che va da schifo, potete aiutarmi? è lentissimo.
Grazie

Va da schifo non significa niente.
Sii più esplicito nel definire chiaramente di che "male " soffre il PC.

Sarebbe anche meglio se dicessi quel PC come è composto, RAM, SO (32/64 bit) e CPU.

Fai una scansione con Adwcleaner e posta qui il log che crea.

Fai vedere in avvio automatico cosa c'è. Start --> Esegui -->> nel box scrivi: msconfig.

Nella finestra che si apre clicca su avvio. Fai uno screenshot della finestra e postalo qui.

EDIT:
Ti ringrazio ma non credo sia il giusto approccio...
NON vorrei esere impertinente ma visto la sfiducia prova con S. Gennaro.

Scusami dottserpente probabilmente mi sono espresso male, non intendevo mettere in discussione la tua competenza (anche se non la conosco)

Grazie cbbusto, mi scuso per le poche info ma, come avrete già capito, non sono molto pratico...
All'avvio continua a caricare (cosa non so) per molto tempo e, mentre carica, ovviamente, non mi fa lavorare.
In generale è più lento del solito, ma l'esagerazione è all'avvio.

ho fatto lo scandisk e non ci sono problemi

ecco il log di hijackthis

O23 -Common Files\MAGIX Services\Database\bin\FABS.exe

O23 - mbamscheduler.exe

O23 - mbamservice.exe

O23 -Mozilla Maintenance Service\maintenanceservice.exe

Se non usi Gogle Chrome, Picasa e Google Earth disabilita anche questi:

023 - (gupdate) - Google Inc. - C:\Program Files (x86)\Google\Update\GoogleUpdate.exe

023 - (gupdatem) - Google Inc. - C:\Program Files (x86)\Google\Update\GoogleUpdate.exe

023 - Common\Google Updater\GoogleUpdaterService.exe

Questi mettili in Avvio Manuale:

023 - FLEXnet Publisher\FNPLicensingService.exe
023 - FLEXnet Publisher\FNPLicensingService64.exe
023 - Skype\Updater\Updater.exe
023 - Western Digital\WD SmartWare\WDBackupEngine.exe
023 - WD Drive Manager\WDDriveService.exe

N.B. Se capita che qualche programma non funzioni bene, cerca il servizio ad esso collegato rifai lo stesso percorso di prima e nella finestra clic su Avvia.

Non mi hai ancora detto che Antivirus usi ?
Fai sapere se l'avvio è migliorato, di norma si dovrebbe avviare tra i 20 e max 90 secondi, dipende dal pc.
Ciao

Volendo si può fare ancora qualcosa, Disabilitare le funzionalità inutili o che non si usano mai, quindi non vengono eliminate come succedeva prima con XP e si possono sempre riattivare senza problemi, ti presento un link dove trovi le spiegazioni e le descrizioni di cosa è possibile Disabilitare, quindi devi scegliere.
Quì: http://www.ottimizzazione-pc.it/disabilitare-le-funzionalita-inutili-di-windows/
Ciao.
