viruses have been detected on my MacBook Air. What should I do
Since browsing the web last week, I have been getting constant notices that I have viruses. Clicking on the link provided brings me to a McAfee scan site, that when prompted, scans and finds 5 viruses. It then says I need to buy the antivirus protection software. Is this real or a scam? Should I buy antivirus software from McAfee or another provider (like Norton)?
