Useful tips
Before calling
- Activation code: can be found in the email you received from the online store. You can also find your activation code on the CompanyAccount portal if you added it previously.
- Or key: can be found in the product itself, in the window containing the license information.
- Your device's specifications: the type (desktop computer, laptop, mobile device, etc), brand, model, processor, volume of RAM and main memory, any peripheral devices connected to it.
- Operating system information: type, version number, localization language.
- Information about your Kaspersky Lab application: the application version number and the version number of its components.
- Information about applications made by other companies installed on, or recently removed from, the device.
During the call
- Remember that the support engineer cannot see your device. He will take his decision based on the information you give him during your conversation. The engineer may not know information that you consider obvious. Therefore, please describe your issue in as much depth as possible: when it occurred, what preceded it, and what measures were taken to eliminate it. Try not to miss even the smallest detail.
- Please be aware that not all issues can be resolved over the phone. We may need time to prepare a comprehensive response, along with additional technical information you may be unable to provide.
General recommendations
- Before contacting technical support, visit our Knowledge Base. Your problem may already have been solved.
- Make sure you have the device on which the issue occurred readily to hand. This will save time.
- If you don’t currently have a Kaspersky Lab product, the support engineer will help you choose one.
