What components do you have installed ?
Some of them may be a taster/trial (read hook), if you are using your system for a use that these function may aid/protect then you are highly likely to get an ad/promotion for that.

If you have the SafeZone Browser installed, that may be a triggered by any on-line banking and may also have something to do with SecureLine VPN ads.

I do a custom install and only install the basics, it is worth trying the minimal install that drops a couple of shields that I think should be included (the mail shield and behaviour shield) also software updater. Pretty much everything else I leave as most of them I already have covered with other software.

I’m sure much of that I’m fairly sure results in less ad/promo popups.
