Does AutoCAD have any mechanisms to guard against macro viruses, such as a virus checker?
Yes. AutoCAD includes a virus protection mechanism for VBA macros, which reduces the risk of infecting a computer with a virus embedded in a drawing file. Note: AutoCAD does not have a virus checker that you can use to check for macro viruses in VBA projects embedded in DWG files. Although the virus protection mechanism for VBA macros is enabled by default, you can use the following procedure to ensure that protection is enabled: On the Tools menu, click Macro > Macros. In the Macros dialog box, click Options. In the Options dialog box, select the Enable Macro Virus Protection option, and click OK. Click Close to close the Macros dialog box. When you open a drawing in AutoCAD with protection enabled, the program detects if a VBA project is embedded in the file. If there is a VBA project in the file, a warning dialog box is displayed that gives you the option to disable or enable macros, or not to load embedded macros at all. The following options are available in the warning dialog box
