My mac seems to be infected
My computer somtimes (several times today) plays a song suddenly through I-Tunes automatically but does not show any other symptoms of infection. So I downloaded Bitdefender and Avira and scanned the whole computer but could not find any infected files.
Question 1. Is my computer infected? If not, what else causes to play music?
Question 2. Should I purchase a more advanced anti-virus software?
Thanks for your help.
