iTunes slowing my pc down

Hi, thanks for the help. I tried the winsock reset and that didn't work. I then looked at the article but don't see any software other than microsoft. After I run the Autoruns software and goto the Winsock Providers tab, all there is is WindlowsLive Local NSP and Windows Live NSP. The publisher is Micosoft Corp.

I have gone to Windows update and checked for updates. There were some to install but this didn't change anything. This is a brand new computer so I haven't installed much on it yet. A couple of things I have installed are Sonos Controller and ZoneAlarm Internet Security Suite, (I removed the Nortons version that came with the computer).

I have reinstalled itunes 64 bit and the computer slows down so much you can't use it. I uninstalled it and then it works ok. Another thing I have noticed is that when iTunes is installed, if I switch off my home network before switching the laptop on, it runs ok, but as soon as I switch the network on, that is when it slows down to a stop. Could the problem be something with iTunes connecting to the internet?

I have uninstalled ZoneAlarm and then reinstalled iTunes and it seems to work ok now and doesn't slow down the laptop. Perhaps it was the issue with iTunes trying to access the internet and ZA stopping this? Would you happen to know what settings I would need to allow iTunes access through the ZA firewall or should I try another virus program like Nortons instead? Would I even have the same problem with whatever virus checker I get?

Well, something seems to have worked. I uninstalled iTunes and ZoneAlarm. Reinstalled iTunes and everything worked fine. Then I reinstalled ZoneAlarm and everything still seems to be working fine. Well, for the past hour anyway! I hope this may have resolved the issues I was having. I'll keep fingers crossed and hopefully it will continue to be all good. Thanks heaps for your help :-)
