System freezes when connected to internet

[windchimes]

My computer freezes when connected to internet. This happens occassionaly and then there is no other option other than manually restart it. But then too system shows difficulty to boot in. I searched the machine with BitDefender and Spybot and there are
no threats detected. Any idea why this would happen? (Os used is XP2, Browse Opera , 2GB RAM , AMD Dual Core 2.01Ghz..)

It's so simple.. Just go into Control Panel ( Start -> Run -> Control ) and then switch to Security Center and then to Automatic Updates and then switch off..
