Web Shield, Mail Shield, File Shield
Automatic virus definition updates
Why choose this product?
avast! Free Antivirus for Mac offers three shields and on-demand scanning. Our Web Shield and Mail Shield combine to check the vast majority of incoming data from the Internet, while File Shield 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.
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.
Alert messages are displayed on-screen whenever a threat is detected.
The File Shield scans the binaries of started applications and all files at the time they are modified.
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.
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.
The scanning engine is automatically updated with our regular VPS database updates.
