4.8 is quite an important update for us.
It contains the following major improvements:
- a built-in antirootkit module
- a built-in self-defense module
- starting with v4.8, avast is now officially an antispyware application, too (CheckMark certified).
Plus there’s a number of not-so-big new features, such as the ability to track scan progress and a largenumber of improvements in both the scanning engine and other components (such as the boot-time scanner, and the updater).
BTW This first beta build will be followed by another one (most likely in about a week). This is because it still doesn’t contain some of the anti-rootkit functionality (so far, boot-time scan can be used to detect/remove rootkits; in the next beta, the GUI scanners will also feature antirootkit capabilities).
Also, in this first version, we’re still aware of some methods to bypass the self-defense module, and these are being worked on continuously. This especially applies to the ashDisp.exe process which is somewhat harder to protect than the rest (i.e. the avast services) as it shares the user’s logon session and is thus more easily attackable.
