Black Friday's ads were INCREDIBLY ANNOYING, INCREDIBLY ANNOYING . After today's "Upgrade to Premium, 25% off" pinned popup, I definitely WILL NOT upgrade to premium anything from CCleaner because I don't want more of these obnoxious popups. Tell your marketing dept that these popups have had a direct negative effect on my opinion of this company and CCleaner.
