what is macdefender and is it needed for macbook pro
What is Macdefender? This software tried to download on my computer by itself and during that process said I had viruses on my computer including a trojan. Is it necessary to have a virus software on my Macbook pro? Should I be concerned that several viruses were noted and if so, what should I do? Thanks.
MacBook Pro, Mac OS X (10.6.7), virus ware, spy ware questions
