On systems that cannot perform authentication, you should always disable macros when you are not certain of their purpose or functionality. By choosing to disable the macros, you prevent this and any macro virus from running, rendering them harmless. The virus is only activated if you open the attached Word document and choose to enable the macros or if your macro Security Level is set to Low . Double-click the Tools menu, point to Macro , and then choose Security . Select the level of security you want.
High security allows only macros that have been signed to open.
Unsigned macros are automatically disabled. Medium security always brings up the macro protection dialog box that allows you to disable macros if you are unsure of the macros. If so, run anti-virus software containing the latest update and scan your system often. Support for this particular virus is already available from a number of anti-virus vendors. If you are not able to run anti-virus software, it will be necessary to delete or rename your Normal.dot file.
