Last night we did a software update to all our stores using the Setup Builder " web install"

We have successfully used this to install in the past but last night we had problems with all the the computers that were running Symantec.

Symantec removed a couple of EXE files that updated during the install.

We have code signed all the exe's and the install itself.

Is there anything else we can do to prevent Symantec thinking this is a virus?
