Google Chrome – 2 odd Word files, resistant to being deleted … :(

[Lenovo laptop; Win. 10; Outlook 2010; Word 2010; Google Chrome]
[enter image description here]one
I see 2 files that appear on my email pages, directly from Microsoft Word, enter the description of the image here and I can not get rid of them at all. I find it difficult to describe them. With your permission, can I send 2 screenshots so you know what they are, please?

Thanks so much for any help! 🙂
