- Improved Antivirus and anti-spyware engine performance – The scanning engine has been optimized to allow faster scans of EXE files – twice as fast, while scans of text contents (such as web pages and documents) are up to 10 times faster.
- Continuous Streaming Updates – Every day, at least 250 virus-database micro-updates (the size of a simple text message, every 3-5 minutes) give you real-time protection against zero-day threats.
- Faster Installation – We’ve dramatically reduced the size of the installation file to about a half, so avast! downloads/installs even faster. And the installation process has been simplified to one-click – no hassle.
- New Design of the User Interface (UI) – Following on the success of the previous avast! UI, we listened to your feedback and improved the experience. We simplified the navigation and action buttons and reorganized the Settings in one simple place.
- Browse securely & privately – We added a Do Not Track feature to our browser plugins that identifies tracking software and gives you control over what companies can follow what you do online.
