Cant access Internet after installing Kaspersky

After getting a original license for Kaspersky Internet Security 7 after doing a review about it I was aghast to find out that my brother has already installed a cracked version of Kaspersky Internet Security.The problem is after installing Kaspersky I'm just not able to access some sites of the internet. I can't access Google but I can access MSN :( . Even uninstalling Kaspersky doesn't seem to work. I was hoping to kick start my other blogs after getting the broadband connection but I guess that have to wait. I was told that Dialog customer service is pretty good , well now I have the chance to find out ;).
