ciao a tutti.
ho un problema, ho cercato già nelle diverse discussioni una soluzione, ma ogni problema mi sembra a se.
fatto scansione con hijackthis trovate le due presenze power offer...allora l'ho eliminato dall'avvio attraverso "msconfig", l'ho eliminato dall'avvio con "regedit", poi ho eliminato la cartella utenti\publicco\poapp, dove c'erano il plauncher e il server e dei .dll relativi a questi, poi ho visto che si è spostato in utente\appdata e l'ho elimato anche da li, ora non è più ricomparso, anche eprchè ho notato una cartella proprio in appdata vicino ad altre applicazioni nominata "power offer" l'ho aperta e dentro c'era l'unistall e l'ho disinstallato come un normalissimo programma.

ora non mi si aprono più le finestre pubblicitarie con chrome ed è sparito dagli avvi e dai processi in corso. In gestione attività e servzi sono presenti i due elementi ma vengono dati come "interrotto".

Ciò che mi disturba e trovare ancora le due stringhe (se posso chiamarle così) sul log di hijackthis che vi copio qua di seguito.

viene scritto file missing ma mi infastidisce lo stesso. altre operazioni per migliorare il log?

grazie a tutti per l'attenzione

Fixa queste voci:
R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = *.local
O2 - BHO: Bing Bar Helper - {d2ce3e00-f94a-4740-988e-03dc2f38c34f} - "C:\Program Files (x86)\Microsoft\BingBar\BingExt.dll" (file missing)

Poi per le 2 voci citate prova in questo modo, vediamo se si eliminano:
Vai in provvisoria, poi Start / Esegui / digiti;
sc delete PosService e dai OK
Poi sc delete ServUpdater OK

Poi in mod normale installa Malwarebytes QUI lo devi aggiornare e poi fai una scansione COMPLETA non veloce, elimina quello che trova.
Ciao

Io lascerei stare, il log non presenta altri problemi e mbam non ha trovato niente, quelle 2 voci non creano nessun
problema, se il pc funziona bene non farei altri interventi.

Infatti Power Offer non è un infezione si tratta di un adware che ti apre finestre popup del browser di pubblicità e ti mostra annunci pubblicitari di ogni tipo. Si autoinstallano senza che te ne accorgi, spesso quando installi programmi che includono l'installazione toolbox e toolbar varie che dimentichi di deselezionare.
Visto che non ci sono malware non c'è pericolo, Usa Ccleaner per rimuoverlo vai in strumenti/Disinstallazione programmi e lo togli, poi fai una pulizia compreso il Registro, dopodichè svuota tutta la cache e i file temporanei.
