Gwamparlofish, aiuto!

[JHY93]

Salve a tutti, come da titolo, avrei un problema con questo file, è un eseguibile denominato Gwamparlofish che viene rilevato da Avast ogni 30 secondi. Il computer non è il mio, è un computer aziendale e quindi preferirei evitare di formattarlo.
Oltre questo è pieno di adware :\
Potreste consigliarmi come procedere? Ho seguito la vostra guida fino al punto in cui devo effettuare una scansione con hijackthis e questo è il log:
