Current list of vulnerable file name extensions
In this list, ? symbols represent wildcards—Dr Solomon’s Anti-Virus
substitutes any character for the ? sothat it scansmore than one file type with
similar extensions. For example, the software will use the .XL? wildcard to
look for viruses in Microsoft Excel spreadsheet (.XLS) and template (.XLT)
files.
 NOTE: Network Associates recommends that you scan your system
thoroughly during your first scan operation, or periodically thereafter,
without limiting the scope of the scan operation to these file types. This
ensures that your system starts in a virus-free condition. You can then
use this list of extensions to limit the scope of later scan operations.
