[Double-A]

Hello, the internet in our house is extremely sluggish and I'm worried that our computers may be infected with viruses. Can anybody recommend me a good antivirus software for Mac computers? Thank you.

Unless you are getting popups and browser redirects, I doubt your slow internet is due to you Mac being infected.
