Salve Giuseppe66,
Deve semplicemente fixare il percorso... O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file).

Deve semplicemente cliccare il percorso da me sottolineato con un "V" per poi bliccare il tasto "Fixare" e ravviare il Computer, per far si che siano apportate modifiche della rimozione file.

Salve giuseppe66,
io la consiglio di disinstallare il suo antivirus e installarsi Avast Home Edition, ingrado di distruggere in modo totale il suo virus.

continua a non voler far la scansione completa, al 1% si spegne e si riaccende, pero' con la scansione rapida tutto ok..bohh

Ciao Giuseppe, questo può anche essere sintomo di una infezione..quindi per prima cosa io cercherei di escludere questa causa e poi proverei a cercare altre cause.

Per ora proviamo così:
Scarica malwarebytes.
Installalo ed aggiornalo.
Disconnettiti completamente da internet e disattiva momentaneamente la protezione in real-time di kaspersky.
Avvia una scansione completa con malwarebytes, salva il log finale e postalo qui.

Non sembra ci siano problemi di infezione, l'unica cosa trovata è all'interno del cestino (svuotalo)

Hai provato ad eseguire la scansione di kaspersky in modalità provvisoria?
