Salve a tutti! Ho un problema: da qualche giorno ogni volta che apro internet explorer, o meglio che dalla pagina iniziale scrivo un nuovo indirizzo web, kaspersky mi fa comparire una finestra dal contorno giallo che dice:
 
Il processo sta eseguendo azioni sospette
 
Riskware: Hidden data sending
Processo in esecuzione: C:\Windows\Explorer.EXE
 
I dettagli dicono:
Il processo C:\Windows\Explorer.EXE (PID: 3684) sta tentando di inviare dati attravero un processo attendibile.
Destinazione: http://89.188.16.43/go//
Dati: j e una parentesi graffa (scusate ma non riesco a farla sulla tastiera )
Dati codificati:
cmp=vm_mg_kw&uid=
8f5b9e0693d511ddb689164321cfffff&rid=zdez&guid=
32d9d6789d4f4ff4baba69e434a46ab1&affid=164321
&lid=www&url=http:%2F%2Fwww.bigmaxicinema.it%2F&v=1156
&m=an2g
 
Ho provato a cliccare su Nega, a fare scansioni, a scaricare programmi per gli spyware, ma nulla, il problema rimane.
Ringrazio chiunque mi risponda
