Why do i see ads on my social media camera roll

[Android Central Question]

So for a while I have seen ads on my Snapchat and Instagram whenever I try to share a picture from my phone's storage, but I don't see it on my actual gallery. I only have apps from Google play and McAfee and Clean Master don't find anything suspicious

First, uninstall Clean Master (and any other Cheetah Mobile apps - unless you don't care that all your data is being sent to China - including logins, passwords, etc.)

Second, SC and IG may not honor a .nomedia file, so any pictures (including ads that your apps download) that are kept in folders with a .nomedia file in the folder won't show up in a media app - but will in SC or IG. Email SC and IG.
