C'è qualcuno che mi controlla il mio Log HijackThis per vedere se ci sono problemi.
Grazie

Ciao cbbusto,
Le voci C:\ProgramData\DatacardService\DCSHelper.exe e Service: HWDeviceService.exe penso siano legate al programma di installazione della chiavetta Internet e353 21.6 della HUAWEI Mobile Broadband che adopero in poche occassioni.
Questa voce: Service: 602Updater - Software602 a.s. - C:\Program Files\Common Files\soft602\602updsvc\602updsvc.exe non la conosco
Il sito redshift.maris.com è legato a un programma di astronomia in inglese che ritengo sicuro perchè lo adopero da sempre .
