ESET Smart Security 7 is an early preview release of ESET's latest antivirus package. As before, it has so many features it's more like a security suite: you get an antivirus engine, social media and web browsing protection and an antiphishing module.
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.
The Antiphishing module now blocks scam sites, and allows feedback (both reporting of suspect sites and false positives) from users. And the package 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.
