If you want to change your current basic license (for example, from Anti-virus to Comprehensive protection) or add additional components (Anti-spam, SMTP or Control center) to your existing license, you can do this at a renewal costs.
Once you activate your new serial number, you will be able to immediately use new additional components and your old and your new license terms will sum up.
Users of both expired and still valid licenses can benefit from these license upgrade terms. The previous/current license term must be at least 6 months.
No upgrade is possible for Dr.Web bundles and curing utilities.
