Salve.Ho questo strano processo iexplore.exe che sta nel taskmanager pure quando non sono connesso.

Prima di postare qualche log di hijackthis aspetto voi cosi facciamo tutto insieme.Grazie anticipatamente.

Ciao stoart;
effettua prima, una scansione online con kaspersky e successivamente scarica superantispyware; aggiornalo ed avvia una scansione...

fammi sapere..

tutti questi sono in autoloading, potrebbe essere qui in mezzo il problema, hai anche un sacco di registrazioni programmi rimandate.
In ogni modo prima prova i consigli di Gorka

Da quel che dici è probabile che tu abbia qualche elemento nocivo attivo nel tuo pc.

Ti consiglio di iniziare ad eseguire delle scansioni in modalità provvisoria con antivirus e antispyware (alcuni free li trovi indicati in questo topic).

E poi ci posti il log di hijackthis
