F-Secure DeepGuard is blocking Adobe Reader DC

jimg972

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

Hi @jimg972

Thank you for reaching out to F-Secure Community.

Can you try to check on this Guide and confirm if the program is listed on the block rule:

Allow applications that DeepGuard has blocked

Looking forward to your update.
