ed eccomi di nuovo a chiedere aiuto...ho trovato in programmi una voce che non ricordo di aver installato:"ffdshow".ho provato a disinstallarlo con ccleaner,ma non c è verso,e neppure da installa applicazioni...il suo disinstaller se cliccato presenta una finestra totalmente amorfa. esiste qualche sistema per eliminarlo?tra l altro quando ci clicco sopra per aprirlo mi da la clessidra per un paio di secondi poi piu nulla...il pc non va benissimo,ma credo che dipenda molto dalla sua eta e dai maltrattamenti...grazie anticipate e buona serata.
ps non posso scaricare malwarw perchè il sistema operativo è w me,ed eset online scanner ha dato esito negativo

si,avevo trovato anch io quello...il fatto è che non c è verso di disinstallarlo,comunque l importante è che non sia un virus o similiare...ciao e grazie

grazie monsee,allora sono piu tranquillo adesso.probabilmente si sara' installato come programma aggiuntivo a qualcos altro,mentre cercavo di capire come usare il masterizzatore che mi hanno regalato.tutti preziosi come sempre.grazie e buona giornata
