Frequently Asked Questions

Q: What is License information?
A: License information is your product’s unique identifier.
Q: What is the difference between the License Number, Installed keys and License information?
A: All these terms mean the same thing, i.e., License information. Different terms were used in different product versions.
Q: Why do I have to renew my license?
A: If your license has expired, you cannot receive up-to-date protection for your computer. Because thousands of new malicious programs appear every day, it would be virtually impossible to remain protected without regular antivirus database updates. That is why we strongly recommend that our customers renew their licenses before they expire.
Q: When should I renew my license?
A: It is best to renew your license no earlier than 14 days before the expiry date and no later than the date the license expires.
