F-Secure DeepGuard is blocking Adobe Reader DC

jimg972 Posts: 1 New Member

I am using FireFox, Adobe Reader DC and AOL. An AOL email has a PDF attachment. When using Firefox to open AOL, I click on the PDF attachment in the email to view the PDF in Adobe I get the following message:

"There was an error opening this document. The file is already open or in use by another application".

If I disable DeepGuard I can open this PDF attachment with Adobe Reader DC.

Any help would be appreciated
