PDF - files Frustrating

I am getting to a point to completely remove AVAST from my laptop.
If I create a PDF from Word it picks it up as threat then I go to Virus chest add exception then ots back in the folder where I saved it in but as soon as I add it as an attachment it bombs out again and I cannot send a PDF I created.

I have searched for all kind of ideas to resolve this issue AVAST youre great in protecting but its getting really frustating and I have no idea who to ask for help.
