We're glad to announce a new major version of "avast! Free Antivirus for Mac". The current popularity of Apple products also makes them more interesting for the bad guys so we thought it would be good to prepare for the battle sooner rather than later. The new version has been almost totally reworked compared with our previous solution for the Mac OS.
We're kicking off with three shields and an on-demand scan. The Web Shield together with the Mail Shield will check the vast majority of incoming data from the Internet. avast! Free Antivirus for Mac is also equipped with a File Shield, which scans all programs stored and executed from your hard drive. Everything is packed in a brand new GUI and is now available as a public beta.
On-demand scanning: It's possible to scan the whole file system, network volumes or a mounted removable volume. You can also run a custom scan. Scan reports are automatically archived and are accessible from the GUI at anytime.
On-screen alerts: Alert messages are displayed on-screen whenever a threat is detected.
File Shield: The File Shield scans the binaries of started applications and all files at the time they are modified.
Web Shield: The Web Shield monitors and filters all HTTP traffic coming from web sites on the Internet. Connections from your web browser are redirected to the Web Shield module. The Web Shield in turn connects to the requested web server and while downloading the content, it simultaneously scans it for viruses and Trojans. Only clean data is delivered to the browser, all malware is stopped before it gets saved on your Mac.
Mail Shield: The Mail Shield monitors and filters all POP3 and IMAP traffic coming from mail servers on the internet. It does not prevent saving of infected files (doing so could lead to irreversible data loss), it just detects them. The File Shield prevents any infected attachments from causing harm to your system.
Automatic updates: The scanning engine is automatically updated with our regular VPS database updates.
Drag and drop functionality on the Dock icon is not available when the GUI is not running.
Some of the avast! windows aren't automatically activated during application start-up and may be hidden behind other application windows.
Sometimes Apple's default icon is shown in the Dock and Finder instead of the avast! icon.
The Growl framework (http://growl.info) is necessary for the pop-up alert functionality. We recommend installing Growl before installing avast!
Some items in the menus and some buttons in the GUI are greyed out / disabled as their functionality is not yet fully implemented.
Installation & Uninstallation:
To use the Mail Shield, you need to disable encrypted POP3/IMAP connections in your email client's settings so the traffic can be scanned. By default, the Mail Shield encrypts all outgoing traffic itself if the mail server supports it (encrypted connections can be forced for selected mail accounts in the Mail Shield settings).
Uninstallation must be carried out from the application's menu bar - item "Uninstall avast!"
