You can renew a valid or expired license of three months or longer (including OEM licenses) at a discount. There is no expiration date limitation when it comes to renewing Dr.Web licenses. You can renew one key file at a discount only once.
When registering a new license, you must submit your old key file or Dr.Web serial number—valid or expired—to receive a discount. If, when registering the new license, your current license has not yet expired, the remainder of its term will be added automatically to the term of your new license.
