In a new partnership between the social networking giant Facebook and the security vendor Trend Micro, HouseCall is being made available to Facebook users in order to protect accounts against malware. HouseCall, which is a free security solution provided by Trend Micro, will scan and remove malware from infected accounts, enabling Facebook users to continue using the service safely. Facebook users who have a potentially infected account will be given the option to download HouseCall, which will then scan the account and provide a notification when analysis is complete. The notification will let users know if the cleanup was successful or unsuccessful, and from that point on, will provide mitigation efforts to keep accounts malware free.
