Its well-organized interface shows all the available features in the main window, which allows easy understanding and ease of use. Four scanning modes are available: quick scan, full system scan, removable media scan and select folder to scan. The last one is an in-depth scan of a specified location. If you are in a hurry, select "Quick scan" mode, it only lasts for a few minutes while "Full System" mode needs at least half an hour. Even if you have already installed an anti-virus on your computer, you can install Avast as a second anti-virus software for more safety thanks to compatibility mode. When installing Avast, you can select the components that suit you really. With this new version, no need to wait for a traditional database update, Avast Virus Lab cloud will send each virus signature to you in real-time.
