How to solve domain slash domain xampp problem?

My configurations are following. In hosts file:

    127.0.0.1       www.example.sk

In httpd-vhosts file:

<VirtualHost *:80>
ServerName www.example.sk
ServerAlias example.sk
DocumentRoot "C:\projekty\example.sk"
<Directory "C:\projekty\example.sk">
    Options +Indexes +Includes +FollowSymLinks +MultiViews
    AllowOverride All
    Require local
</Directory>

After typing example.sk in browser it redirects me to example.sk/example.sk, where i can install wordpress etc, but url is always example.sk/example.sk/... How can i solve this?
