I am having difficulty opening email attachments and wondered if avg is responsible
I am using outlook 2016 for email - is pre viewer involved or is it a security setting within avg internet security that is responsible
The same files will not open from a memory stick

Attachment wont open due to "error with microsoft excell previewer"
Is this an issue with AVG or the Office file?

Hi Paul,
We understand your concern, could you please confirm if you have tried disabling AVG and then checking the issue? Please follow the steps provided by the previous technician and check once.
Thank you!
