five tips to protect their computers and personal information from Mc Afee

Stick to well-established and trusted sites that include trust marks (icons or seals from third parties verifying that the site is safe), user reviews and customer support. A reputable trust mark provider will have a live link attached to its trust mark icon, which will take visitors to a verification Web site of the trust mark provider.

Do not respond to offers that arrive in a spam email, text or instant message.
Preview a link’s web address before you click on it to make sure it is going to an established site. Never download or click anything from an unknown source.
Stay away from vendors that offer prices well below the norm. Don’t believe anything that’s too good to be true.

Make sure to use trusted wi-fi networks. Don’t check bank accounts or shop online if you’re not sure the network is safe.
