avast! Hardened Mode
is used to further lock down the security of the computer and is recommended for novice (inexperienced) users or for administrators looking to lock down settings without restricting accounts. This feature relies on avast’s file reputation service which crowd-sources information from almost 200 million devices currently protected by avast! products. Hardened Mode has two settings...Moderate and Aggressive which can be accessed (enabled) by launching avast!, selecting Settings > Antivirus.Moderate
: avast! automatically blocks files that are detected as suspicious by initial analysis. Moderate hardened mode essentially stops the execution of any suspicious file immediately.Aggressive
: avast! analyses if the file is included in it's white-list database located in the avast! Cloud. If the file is present in the white-list, it is determined to be safe and execution is permitted. If the file is not present in the white-list, execution is blocked.
Hardened mode cannot discern correctly whether a program is safe or not so when the settings are too high (Aggressive), it seems to block almost everything....erring on the side of safety.
