Hi everyone,
SafeZone has been one of the key features of the premium (paid) versions of Avast for years, and yes, we're now (for a limited time) making it available to a portion of our free users as well, to give it a bit more exposure and also, quite honestly, to accumulate as much feedback on it as possible. SafeZone is great for online transactions (e.g. shopping and banking), as it runs in its own sandbox and is able to shield a bunch of attacks - both local and network-based, but it can actually be used for casual browsing as well.
Give it a try and tell us what you think. Again, this has been one of the pillars of the premium versions, and we're now experimenting with it in the free version as well.
Thanks,
Vlk
