ciao r 16, si in effetti mi sono fatto prendere dal panico ed ho fatto qualche pasticcio abbiate pazienza, anche perchè non riuscivo più a capire cio che stavo facendo ed il computer non rispondeva come volevo, vi chiedo scusa e vi ringrazio per la vostra premura
ho rimosso i file che mi ha scansionato malawarwbyts
vi ringrazio ancora, spero di non commettere più lo stesso errore
grazie nuovamente

questo è il log che mi hai chiesto
