McAfee has been focusing on computer security since 1987, when the company was founded by John McAfee. The company offers antivirus software and VPN connection for consumers as well as businesses. A protection program like the one from McAfee, which you install on your computer or smartphone, helps you protect your data, recognize when a website is spoofed, and remove any compromised files that might be used to install ransomware or spyware on your device. With a reliable antivirus, you are safe while browsing, shopping or making bank transactions even on free Wi-Fi in your favorite cafe.
