I use the commercial version of Dr.Web for Android (not a lifetime license). What data do I need to provide to the Doctor Web technical support service to get help?
If you're contacting technical support:
From the Dr.Web page at Google Play, through My Dr.Web Portal, or via the support form on Doctor Web's site, specify your serial number or your Google Play order number and your Gmail address. If you do not have the order number, then you probably purchased the Dr.Web license from another site. In this case, you need to submit your serial number. You can find your serial number on My Dr.Web Portal.
Use the link in your order confirmation — click on the link found in the support request form at Google Play, select the request topic, and ask your question. We will obtain all the required information from Google Play automatically.
