Microsoft Outlook and Salesforce toolbar for Outlook causing 'Exploit Cryptoguard' detections

I am quite sure these are false positives. 

When adding an image [.jpg or .png] to a case in the Salesforce Toolbar for Outlook it gives an alert for 'Exploit Cryptoguard'.

By going through the Root Cause analysis, the only programs effected are Outlook and the Salesforce toolbar.  The only IP addresses are our mail server and the Salesforce.com IPs. and the only business files effected are the two jpg files the user is trying to attach.     Does anyone have any idea how to stop this from happening?

Outlook is 2013 and 2007
