No, that’s not true. When you buy the anti-virus, you are paying not only for the program itself, but also for the right to get anti-virus database and module updates as well as the opportunity to contact the technical support service while your license is valid. Nobody will ever come after you for additional money! Proof of this can be found in the Dr.Web license agreement which you are invited to read before you install the anti-virus. Doctor Web assumes a number of obligations and guarantees the following:
‘Throughout the entire software usage period, the User is granted the right to receive through the Internet virus database updates as well as upgrades of the software modules as they are made available by the Rights Holder’.
The Dr.Web license agreement is a legal document that guarantees your rights as a consumer.
