Avast! Antivirus offers protection against CryptoLocker
Avast! Antivirus offers protection against all known variants of CryptoLocker.
AVAST users should be safe from infection during the short period when the malware is new and “undetected” as long as AutoSandbox and DeepScreen are active. The infection is prevented by means of a dynamic detection.
So it is safe to say that only premium customers of Avast! are protected from CryptoLocker, correct? Because the settings you mentioned above are only offered to customers of Avast! at a premium price (upgrade) which would mean that those that have Avast! free are not protected.
Oh, if it is only Avast Premium that offers the AutoSandbox and DeepScreen features, then I guess you are right. The free version users may not get the protection.
