The new version strengthens the day-to-day safety of computer users â€“ even before their computers are fully booted â€“ and comes with an enhanced ability to detect zero-day threats as they appear.
Rootkits such as the Alueron manipulate the kernel of the operating system code to hide themselves, enabling data and financial information to be more easily stolen without the computerâ€™s owner being aware of the infection â€“ and also making it difficult for many antivirus programs to detect and completely remove them. The avast! boot-time scan uses direct disk access to bypass corrupted Windows file system drivers as it searches for malware.
Changes in the Behavior Shield have increased the programâ€™s ability to find suspicious code without causing false positives.Â â€œThe key is to identify potential malware more quickly and help other users,â€ says Mr. Vlcek. The revised Behavior Shield is more sensitive than in 5.0, allowing the identification of wider range of questionable items. Data on these items is then automatically sent to the avast! Virus Lab and used to improve overall detection of these new threats as they appear.
Current avast! users will automatically get the new version during scheduled updates. The new version includes avast! Free Antivirus and the paid-for avast! Pro, and the premium avast! Internet Security.
