MasterBootRecord Protection

Avast Free Antivirus / Premium Security

Hi,

I would like to know what kind of MBR protection Avast uses to fight for example this kind of locker : https://www.bleepingcomputer.com/news/security/new-wiper-malware-impersonates-security-researchers-as-prank/

As far as MasterBootRecord modifications by malware,what kind of protection Avast uses?
Has Avast a protection like the Cisco’s MBRFilter code ?

Avast could backup the MBR status at installation time and provide for example a tool to restore to a previous point. I think its a good suggestion :wink:

Kind Regards,
Filipe

Hi,
Avast Anti-rootkit protects MBR from malicious modifications. Before sector write the content is scanned by AV engine.
