Try reinstalling Skype first. If that doesn't work, find out if Skype services have been blocked in your country?

your solution is create a new account, open a Skype program when open the sign in click on "Don't have a Skype name?" and create a new one.

Make sure you firewall program is not blocking skype.

This reminds me when I had the same problem when Skype version 4 came out and it loaded so fast the webcam software was not in place and Skype could not detect the webacam.
The workaround was to right click and exit Skype and restart it but others on the Skype community chose to go back to an older version of Skype.
I'm surprised if its the same problem still as several updates have been made since then I thought it would have been patched - I am now on the latest version

There is a version 4.1 Skype. You might need to upgrade by going to skype.com. If you already have the latest upgrade and you are on a LAN you might want to configure your LAN settings to allow access for skype. Otherwise, if you have a direct internet connection and you can get on the internet with your browser, you'll need to configure your connection to allow skype. If you have McAfee or Norton or another firewall you'll have to go to the program permissions to allow Skype. If you are also using Windows Firewall you can follow these steps to allow Skype to pass through your firewall.

Go to START + CONTROL PANEL, THEN RIGHT CLICK ON NETWORK CONNECTIONS. IN THE DIALOGUE BOX CLICK ON PROPERTIES. IN THE NEXT PANEL CLICK ON "ADVANCED". There you can set your Firewall settings to except Skype, Just click on SETTINGS + ADVANCED + EXCEPTIONS. Make sure Skype is checked. This will tell your computerl to allow skype to access the internet without being blocked by your firewall.

I hope this helps, but usually when you install Skype these settings are changed by the setup program. I suspect you have a firewall you will have to set manually. If you use Zone Alarm or some other firewall you will have to search the for help on your firewall support pages.

Contact customer service to get your account unblocked.

If your account is blocked, please contact Skype customer support by completing the form on the link above. Please choose "My Account>Blocked Account" as your topic and subtopic.

Pretty simply, your Antivirus is blocking Skype from acessing the internet. Personally, I'd uninstall it and use Avast! 
Anitvirus, which is free for home users. I use Avast! and Skype together and have had no conflicts. (www.avast.com)
You might also be able to find a whitelist somewhere in Kaspersky;'s preferences, but I''m not familliar with it and cannot tell you where.
