Bot virus on Mac Book Pro
I have a 13 inch Mac Book Pro running Lion. I got an email from Comcast that my Mac is possibly infected by a Bot virus and they want me to instal Norton Security etc. Can Lion be affected by Bots? I am kind of hesitant to instal the software as I used to have Norton on my old Dell pc and it was always needing updates and constantly downloading info.
MacBook Pro, Mac OS X (10.7.3)
