Strano comportamento e ventola sempre al massimo. Virus?

[Squarabba]

Salve e complimenti per il sito.
Vorrei chiedere aiuto per uno strano comportamento del mio pc portatile.
Oggi ho erroneamente avviato un eseguibile sospetto (società Trend Micro Inc. tipo file iGolds), che apparentemente non ha avuto alcun esito e subito dopo la sua apertura è scomparso.
Il comportamento del portatile sembra normale, a parte qualcosa di strano che ho notato:
tende a scaldare un po' in più, ma la cosa noiosa è che la ventola di raffreddamento non si spegne praticamente mai!!! credete che sia un Virus???
Grazie 1000!!!

ciao Squarabba facciamo un controllo

apri il task manager e vedi se c'e' un processo che assorbe molta cpu e posta il suo nome

poi....

scarica hijackthis e mettilo nella directory C dove avrai preparato una cartella con il suo nome.
Lanci l'eseguibile e clicchi su " do a system scan and save a log" alla fine salvi questo file con estensione *.TXT e lo alleghi ad un post sul forum.

[Squarabba]

...credo che l'unico che assorbe tantissimo sia un programma chiamato Nwosea.exe ...guardacaso nella descrizione mi dice iGolds...

Ho fatto come mi dici e questo è il log, spero che per allegare intendevi questo (è possibile allegare solo gif jpg...?)

[menatwork]

termina subito il processo Nwosea.exe sicuramente non e' niente di buono

Scarica e installa e aggiorna malwarebytes.
http://www.malwarebytes.org/
Aggiornalo: clicca sulla scheda "aggiornamenti" => "controlla aggiornamenti"
Esegui una "scansione completa" (seleziona l'opzione)
A scansione completa, fai clic su OK => Mostra i Risultati.
Assicurarti che tutto sia selezionato e clicca clic su Rimuovi selezionati.
Se ti chiede di riavviare, riavvia per completare il processo di pulizia.
Posta il rapporto .

[Paolo Leonardi]

Ciao, prima di tutto procedi con la scansione con Malwarebytes Antimalware, come ti ha giustamente consigliato menatwork. Al termine postaci il report. Se Malwarebytes non dovesse riuscire a rimuovere il problema, fixa in hiJackThis la voce
C:\Windows\Nwosea.exe
Facci sapere.
A presto!
Paolo Leonardi

[menatwork]

ciao Paolo Leonardi



come vedi ho gia' detto all'utente i passaggi che deve eseguire, non c'e' bisogno di ripeterlo, si crea solo confusione

inoltre quello che tu dici non e' possibile fixarlo

Grazie

[Squarabba]

...sono sicurissimo! maledizione!
ho terminato il processo Nwosea ...ma si riapre e apre un'altro processo denominato ntx.exe!!! ed ora sto scaricando l'antimalware ...speriamo bene.
mi si è già bloccata la navigazione e miracolosamente ora mi ri va!!
...speriamo bene

[menatwork]

apri il task manager e termina anche quello

finisci la scansione con malwarebytes

[Paolo Leonardi]

@menatwork pardon!
Temevo infatti non si potesse fixarlo in HiJackThis... Attendiamo allora il report di Malwarebytes.
A presto!
Paolo Leonardi

[Squarabba]

...la scansione anche se lenta, procede ed ha già rilevato 5 infezioni!
appena finisco la procedura posto il tutto
...ma già devo ringraziarti per il tempestivo aiuto e per la pazienza! grazie davvero.
Spero che sia di monito ad altri sprovveduti come me.
