My internet freezes and won't work until i restart my computer...?

Any ideas.... i downloaded IE7 then the problems occured. I uninstalled it and still continues to freeze. I've downloaded anti-virus, registry fix, and ad and software removal. Still samd problem. My computer might break pretty soon because i restart it too much. Also, my msn messenger started to act up it takes like three seconds for whatever i type tp appear on my screen. Please any ideas.. I'm on the verge of buying the Norton antivirus or even taking it in to the shop to clean it.

You certainly have a worm or some virus on your computer and possible your IE and other Operating Systems files are corrupted. I will advise that you just format the computer and reinstall the OS and other software. Get and upto date virus definition for your antivirus. You can safe your files some where self before formating your system.

spybot search and destroy

ccleaner

and use firefox for serving,

if msn is also causing problems and the anti-virus and anti-spyware and ccleaner didn't fix it, use a program called trillian to chat to your msn contacts.
OK why did you dl IE7? It doesn't work with about 85 % of the websites out there. Maybe you should unplug your computer and put it back in the box. Then return it to the store and get your money back. You aren't ready yet, young jedi.
