Avast has now released the final versions of their 2012 security lineup – Avast Free Antivirus 7, Pro Antivirus 7 and Internet Security 7 . The new version ships less than three weeks after the beta release
Avast has moved the virus definition databases to the cloud to provide users with real-time definition updates. Instead of delivering traditional update packages, definitions are now updated whenever they are created. This improves security by reducing the time it takes to update the databases on the client PCs.

The second new feature is a file reputation system which provides information about a file to the user before it is opened, and is also used internally for the decision making process.

A Remote Assistance feature has been added to all Avast 7 versions. This basically gives someone else control over your computer, which may be helpful for tech support for instance. If you are the tech guy in your family, you could use it to remotely log in to other computers to fix issues without being locally present.
Here is the full list of new features:
- New installer
- UI facelift
- FileRep service (cloud based)
- Streaming updates
- Sandbox & Autosandbox improvements
- Browser protection improvements
- Remote assistance feature to help your friends with computer troubles
- Support tool
- Export/Import settings
- Screensaver facelift
- runs on Win8 Developer Preview
There are some additional program features that are not included in the free antivirus version such as automatic sandbox and browser sandboxing module. Avast moves suspicious programs automatically in a sandbox where the program’s behavior is analyzed.

The free version of Avast Antivirus supports all realtime-shields the program ships with, compatibility with all recent 32-bit and 64-bit editions of Windows (including Windows 8 Beta support), and a customizable installation option that makes sure that Avast Antivirus can be installed next to other security software as a second line of defense on the system.
