avast! Internet Security isn't worth paying for, if you're NOT going to utilise all it's features.
Sandbox
> avast! Sandbox doesn't always virtualise applications
> I found Baidu folders in my Program Files, after using avast! Manual Sandbox (for Baidu AV).
> Applications may crash when virtualised, for example, Internet Exporer
> Hard to locate installed apps in sandbox.
> No clear instructions on how to Empty Sandbox (not SafeZone).
SafeZone
> Protected URLs didn't open in SafeZone Browser
> Uses Chromium, not latest version.
Firewall
> Neat features, but not easy to use or configure firewall - More confusing than Windows Firewall
Anti-Spam
> Use Webmail? Then you won't need this.
Software Updater
> Automatic updates limited to Premier version.
Others Tools
> More or less junk
Avast Online Security
> Doesn't always play nice with other browser extensions
At the end of my 10 (of 30 day trial), I concluded that a much better option is to stick with avast! Free Antivirus, Sandboxie and Windows Firewall. However, I look forward to see what Avast has to offer in the 2015 version, especially NG.
