ESET Smart Security 7 is an early preview release of ESET's latest security suite. It includes an antivirus engine, web browsing and antiphishing protection, a host intrusion prevention system, social media protection, a firewall, spam filter, parental controls and more.
New features include an advanced memory scanner, which checks application in RAM, so bypassing many of the tricks malware might use to hide its real code.
A Device Control module builds on the previous Removable Media functionality, allowing you to take complete control over the ways your users can access and work with any given device type.
A new Vulnerability Shield does a better job of detecting your PC's vulnerabilities.
The Antiphishing module now blocks scam sites, and allows feedback (both reporting of suspect sites and false positives) from users. The firewall is smarter, and easier to use. And the suite is also more compatible, running properly on Windows 8, and with a mail plugin which fully supports Windows Live Mail and Office 2013.
As we write, the beta appears to expire at the end of October 2013, so there's plenty of time for testing. Still, we wouldn't recommend you use it for that long: it is a beta, and will contain bugs, so you shouldn't rely on it for long-term protection.
