I am using windows 7 operating system on my computer and I installed Bitdefender internet security 2011 on my computer. After installing I am having several problems with it. The very first is that my computer freezes and I am not able to do then just I have to restart my PC. Then I have also observed that my internet is also going slow and thus I cannot surf properly, and also utorrent doesn’t work properly. So what is the main problem which is happening on my computer?
