I have Norton Internet Security Suite installed on my PC, i always face this problem when I am using the LiveUpdate facility. Basically, when I click 'yes' to start the LiveUpdate process, once the updates have been downloaded and the URL list is being updated the computer becomes very slow, and it is as tho there is not enuf RAM to process all the programs at once and it starts lacking a lot. Now i dont knw why this is happening recently cos my PC can mult-task several more powerful intense programs at once so im not sure why it is slowing down when it is performing this specific task?

I placed this in hardware problems cos i feel it is something to do with the RAM and the Software installed etc, some connection between them or something, i really dont think it should become this slow when performing this task, does anyone know why it is happening and how i could stop it??
