Ciao,

Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su "fix checked ":
O4 - HKCU\..\Run: [cacaoweb] "C:\Users\Sabrina\AppData\Roaming\cacaoweb\cacaoweb.exe" -noplayer

Poi riavvia il sistema e elimina questa cartella:
C:\Users\Sabrina\AppData\Roaming\cacaoweb


esegui la scansione con malwarebytes proposta da tamagon e allega il report

Ciao, vedo che sei nuova, benvenuta.
Dimmi se conosci questo programma ? C:\Windows\AutosetFrequency.exe, mi sa di infezione.
Fai sapere, ciao.

Chiudi tutti i programmi e disconnessa, fixa ed elimina queste voci:

C:\Windows\AutosetFrequency.exe
O4 - HKLM\..\Run: [AFQ] C:\Windows\AutosetFrequency.exe
O4 - HKLM\..\Run: [Acer ePower Management] C:\Program Files\eMachines\eMachines Power Management\ePowerTray.exe
O4 - HKLM\..\Run: [VirtualCloneDrive] "C:\Program Files\Elaborate Bytes\VirtualCloneDrive\VCDDaemon.exe" /s
O4 - HKLM\..\Run: [SunJavaUpdateSched] "C:\Program Files\Common Files\Java\Java Update\jusched.exe

O4 - HKUS\S-1-5-19\..\Run: [Sidebar] %ProgramFiles%\Windows Sidebar\Sidebar.exe /autoRun (User 'SERVIZIO LOCALE')
O4 - HKUS\S-1-5-20\..\Run: [Sidebar] %ProgramFiles%\Windows Sidebar\Sidebar.exe /autoRun (User 'SERVIZIO DI RETE')
Poi fai una pulizia con Ccleaner compreso il Registro, per il registro spunta tutte le voci e consenti di fare il backup dei file eliminati:
