Ciao a tutti, vi spiego il mio problema. Non riesco ad installare l'antivirus. Leggendo su internet ho capito di dover fare una scansione con Hijackthis, ma dato che di computer non capisco un gran che, spero che qualcuno di voi mi possa auitare.

Di seguito riporto il log della scansione:

questo è tutto

Un saluto

Non è che risolvi il problema facendo la scansione con HiJackThis. Questo SW serve per analizzare il comportamento dei SW sui computer.
Se non riesci a installare l' AV il problema è da ricercare altrove come potrebbe essere l' AV stesso corrotto. Prova a riscaricarlo nuovamente e a reinstallarlo.

usavo avira e di colpo è sparito, ho provato a reinstallarlo ma niente.
Allora un mio amico aveva ancora una licenza per norton l'ho istallato. Ho fatto la scansione ma non mi rileva niente.
Qualcosa però c'è di sicuro, in quanto quando navigo mi si aprono siti web che io non desidero.
