# The following innovations have been introduced in Kaspersky Anti-Virus:
* New protection component of the System Watcher provides monitoring of applications activity in the system and provides detailed information to other protection components. Due to the recoverable history of the applications activity, the component can roll back results of a malicious application's actions when such malicious actions are detected by various protection components.
* With the help of the Idle Scan module the computer may be scanned for viruses while you are not working on it, then scanning will stop when you return to work. This allows you to perform a scan regularly and at the same time prevents the reduction of the computer running speed when you need it.
* When Kaspersky Anti-Virus is installed on your computer, you can temporarily switch to Kaspersky Internet Security to assess its features. You can also purchase a license for further use of the application. You will not have to install Kaspersky Internet Security apart from Kaspersky Anti-Virus.
