Does AVG garble PDF's?

Hi Jan,
Please provide us with more information (detailed description, screenshot) so we can better understand what issue you are dealing with.
Thanks

With my MacBook Pro I send an email with a PDF attachment to a ACER Sonic Master/ with Outlook 2013  and WIN 8.1
On this ACER is installed AVG : Gecontroleerd door AVG - www.avg.com
Versie: 2015.0.5645 / Virusdatabase: 4273/9019 - datum van uitgifte: 01/29/15

Other mails with .JPG attachments are received by the ACER system with a "Nameless attachment xxxxx.htm". One attachement for every .JPG attchment.

What is wrong ? Does AVG cause this problem ?
