After install Bitdefender Internet Security 2010 i got some problems:
1. sometime the computer become freeze and i have to press the power button to power off and restart.
2. The internet connectiom become very slow (disable or remove bitdefender the problems fixed)
3. Comflicted with Uttorrent. when i use uttorent to download a Linux Ubuntu Disc on the P2P network, after a while the internet connectton got lost. i have to restart the computer to fix it. when i dont use uttorrent, the network connection doesn't get lost. and when i remove bitdefender and use utorrent to download, the internet connection work ok. I also tried to uninstall the internet adapter's driver and reinstall, the problem still the same.
PS: i install it on Windows 7
