Hello Dave CCleaner,
I have to agree with the other customers who are complaining about the popup. Out of all the software I have installed, yours is the only one that has any form of popups. My other software either places a notification in the software when opening in an un-annoying way or sends a notification email from an address that is for renewals only. The latter allows the customer to move advertising emails from subscription emails. Give us the option or develop an un-annoying way to inform your customers within the software. CCleaner was suggested to me by a Tech Support company, and now that same company is removing it from their clients' PCs. I loved CCleaner in the past but now at a point of reevaluating the software.
