Microsoft Security Essentials is very good and free. It is all the security I use on my Win7 home computer. But I think corporations and businesses need more security than that. Maybe Kapersky

Microsoft Security Essentials could have come out years ago but Microsoft was scared of another anti-trust suit. But with Apple becoming real competition.....Then MS knew they would not be subject to anti-trust

Actually, businesses use hardware-based solutions for Internet security, using a special computer that does nothing but monitor and block viruses, malware, and so on. A good example are the Barracuda Networks rack-mounted devices, which can support up to 5,000 users per device.
