Tech Support i had some viruses

Hello,
I have recently got avg 8.0 for my computer because i had some viruses. i play online poker. Like the second day my pokerstars was not pulling up saying connection error. then a few days later my full tilt account isnt working either. someone had told me that avg doesnt like to allow poker sites to work. i have uninstalled avg and it still isnt working. does ne one kno how to fix this problem with maybe the internet connection settings or something

thanks
matt
