Ezek a fontosabb dolgok hiányoznak az avast! free verzióban:
[bSilent Firewall
The firewall enables you to control incoming and outgoing traffic from your computer. Protection is based on heuristic and behavioral analysis, and a white list of known safe applications. There are three network settings which can be changed depending on the type of connection.
Antispam
New comprehensive SPAM and fraudulent message filter. It works as a plug-in to MS Outlook and a generic POP3/IMAP4 proxy for other email clients.
avast! Sandbox
Enables potentially exploitable programs (such as web browsers) and/or suspicious executables to be run in a safe, virtual environment. The avast! Sandbox is unique as it runs on both 32 and 64bit platforms.
Script Shield
Detects malicious scripts hidden in internet web pages and prevents them from running and hijacking or potentially causing damage to your computer (Internet Explorer only, 32-bit only).
Hamár avast!-ot választod, akkor inkább az avast! Interner Security legyen. Jobb a védelme mint az avast! free-nek.
