Ads are appearing from McAfee, Avast and the PC App Store in the middle of Word, Excel, Microsoft and Google Browser pages, and they are interfering with work efforts on these pages. Some of the ads have loud videos playing when they appear, which interfere with other people nearby as well as the computer user.

If these can be kept to the lower right edge of the page, as expected, it would be better (although these would be better on a strip along the bottom, anyway).
