I keep getting this same ad programme installing itself, and I think it's connected to certain apps on the app store. I've tried uninstalling all recently installed apps to get rid of it but it still persists. It always has a fake 'opt out' option bellow the ads, which leads to this link tracker.tdc.re, but I can't seem to find where this spyware is located and where to get rid of it. This one seems to be pretty common anyway, and I'm wondering if anyone knows how to get rid of it? I'm sick of having to reformat my phone every time this happens, apps with intrusive ad programmes like this should be banned from the app store. Any help would be appreciated, thank you.
