Free security suites for a long time have been extending protection for computers. avast! Free Antivirus 6 has the new WebRep browser sandbox environment and add-on. It has the feature of Sandbox to distinguish malicious programs when they run. The security suite is available in three versions, avast! Free Antivirus, avast! Pro Antivirus and avast! Internet Security.
The AutoSandbox feature identifies suspicious programs, which pose a security risk to computers. The Sandbox option permits a program to be executed, while keeping a track of the types of files that are created, opened, or renamed and the kind of things it writes and reads from the Registry. These changes of permanent nature are virtualized, and when the termination of process takes place itself, the changes in the system it made will be reversed if the program is detected as malicious. It asks from the users whether a program may be sandboxed by default, though one may opt for the automatic option. There is an option for the programs which one always wishes to keep away from the sandbox, and one can prevent it from fully activating the feature. The settings of AutoSandbox are reachable from the option of new Additional Protection option of the left navigation.
