Concerning to:Kaspersky Internet Security 2010
Kaspersky Anti-Virus 2010
The error "Activation error. Server name cannot be resolved." can be generated in certain circumstances.
The most common reason for this error is that your computer is not able to resolve the Domain Name System convention.
DNS (Domain Name System) is a system that “transform” an URL (ex.: www.kaspersky.com) to a numerical system (ex. IP address: 184.108.40.206) that is understandable by Internet.
First step is to verify your computer is able to process this operation of URL -> IP Address transformation:
- open a Command Prompt window with Start - Execute - cmd
- enter: ping www.kaspersky.com
- you should have a result like the picture below
If you receive the correct answer as above, please try this second step:
If the previous two steps do not work, you are probably infected by the virus KIDO (aka. Confiker), so you have to apply this procedure: How to remove network worm Net-Worm.Win32.Kido (aka Conficker, Downadup)?
By default, this virus blocks the access to many Anti-Virus vendors.
You can also use our Kaspersky Virus Removal Tool 2010 for checking your computer that there are no malicious codes blocking the access to Internet.
Once you have applied the KIDO remover, please re-apply the steps 1 and 2 to be sure the DNS resolution now works properly.
Another reason for this error is the use of a third-party Firewall installed on your computer, make sure that an allowing rule is created for the process avp.exe in the Firewall settings.
Firewall secures your computer protection on local networks and Internet. Firewall is a program which monitors data transferred via Internet or local networks. According to the Firewall settings, it blocks or allows data transferring.
If the recommendations described above did not help to resolve the problem, try to activate later (in about an hour).
If the error keeps repeating, create a request to Kaspersky Lab Technical Support via the My Kaspersky Account service. Descibe your problem in all details.
