Is my information in phone leaked?

[Windows Central Question]

Yesterday while surfing a site on UC browser I clicked the back button and it directed me to a page which said UC Web Your personal information leaked, Please visit Google Play, I again clicked back and it said Samsung Your personal information could be at risk, download Privacy Lock from Google Play, Again I clicked back and It said security risk Download Zero Launcher.
But inspite of clicking back it did not take me to the site that I was surfing. I had to close the browser.
My phone already had Avast Security downloaded.
Hence I want to know why did I receive this. Is my information leaked?
My friend told me these were just advertisements to be downloaded from Google Play.
Please confirm me the same.

You're getting (and falling for) pop-up ads...

No need for any anti-virus software on a Windows Phone - Avast included.
