vírus or malware?
I was working on my MacAir yesterday, and suddenly opened a message with the icon of the "system tool" saying in Portuguese "virus found (3) click here to scan", and in English a button wrote, "show". I did it and opened a window of McFee. I don´t have an anti-virus...what shall I do??? Tks!
