The Microsoft Malware Protection Center (MMPC) has recently seen an increasing number of threats using macros to spread their malicious code. This technique uses spam emails and social engineering to infect a system.
Using macros in Microsoft Office can help increase productivity by automating some processes. However, malware authors have also exploited these capabilities. Since Microsoft set the default setting to "Disable all macros with notification", the number of macro-related malware threat has declined. More recently we have seen new threats emerging that include some form of social engineering to convince users to manually enable macros and allow the malicious code to run.
