avast! provides a package of applications that aim to protect your computer from a possible virus infection or other malware threat. If you use it correctly, and in combination with other programs such as data backup utilities, it will significantly reduce the risk of your computer being attacked or infected by a virus, and thus the risk of losing important or private data.

The avast! Internet Security software comes with an antispam filter and built-in firewall. Once installed, avast! runs silently in the background to protect your computer against all known forms of malware. You don't need to do anything else - just install and forget!

Real-time shields
The real-time shields are the most important part of the program, as they are working continuously to prevent your computer from becoming infected. They monitor all your computer's activity, checking all programs and files in real-time - i.e. at the moment a software is started or whenever a file is opened or closed.

Virus Chest
The virus chest can be thought of as a folder on your hard disk with special properties, that make it a safe, isolated place for storing potentially harmful files. You can work with the files in the virus chest, with some security restrictions.

avast! antispam filter
avast! Internet Security includes a fully integrated antispam filter to detect unwanted email.

Spam delivered to your mailbox can result in your mailbox quickly becoming full, as a result which, legitimate emails may not be received. It can also unnecessarily increase the load on the email server, internet connection, local networks etc.

Firewall
avast! Internet Security includes a fully integrated firewall which can be controlled directly from the avast! user interface.

The firewall monitors all communication between your computer and the outside world and blocks unauthorized communication based on a number of "allow" and "deny" rules. In this way, the firewall can prevent sensitive data from leaving your computer and can also block attempted intrusions by external hackers

Command-line scanner
The ashCmd software uses the same avast! scanning engine to detect potential malware infections so the results are exactly the same as running a scan via the normal software interface. The avast! command-line scanner, ashCmd.exe, is normally installed in the directory C:Program FilesAlwil Softwareavast5.

A scan is run from the command prompt using various switches and parameters. To see a description of the parameters, locate the ashCmd file and double click on it. This will open a new window in which the various parameters are displayed.
