INTRODUCING: New avast program update 5.1.864

Hi guys,

I’m glad to announce the general availability of avast 5.1. After almost a month-long beta testing marathon (and 3 beta refreshes just in the last 24 hours), I sincerely hope this new version will serve you well. Even though avast 6.0, equipped with even more features, is coming relatively soon, v5.1 is still a very important update for us. Most of the new good stuff is hidden under the hood.

The most notable improvements are:
- boot-time scanner now available even in 64-bit Windows
- big improvements in the Behavior Shield
- improvements in the antirootkit engine
- improvements in the cleaning module
- stability/performance improvements in the Web Shield
- CommunityIQ improvements
- added support for sound packs
- minor improvements in the user interface
- minor fixes in the firewall
