Hopefully the files you sent to McAfee went through and will produce an update that will stop their detection. However as they may reject them & in any case you may want to ensure something is done by submitting them manually.

When submitting samples via E-mail all samples must be packaged in a .ZIP file. When creating this .ZIP file, it is important to understand that the .ZIP can be no more than 3 megabytes in size and can contain no more than 30 files. Additionally, any .ZIP file created must be password-protected using the password "infected" (minus the ""). Failure to follow these guidelines will cause your submission to be rejected.
