Hello,

I just installed a clean copy of Windows XP Pro on a Dell Dimension 2400, Celeron 2.4GHz with 512MB RAM. IE was working good for a while but now when i browse to new websites, my CPU spikes to 100% and it takes forever to load a website. The only software I installed was Norton Antivirus 2004, and i do notice that is is not a problem when I DISABLE the antivirus realtime protection! What could be happening here? NAV2004 causing the problem?

Thanks,
Adam

You MAY have a virus or trojan that is using system resources, like a denial of service (DOS) attack.

It is also likely that NAV is dragging you down, it's not very resourceful and I've removed it more than I've installed it to rectify problems. But to hit 100%is pretty wild. Are you getting the 100% number from the Task monitor ?

I think it is more likely you have a trojan, virus or spyware installed.

Download ADAWARE for free at

If you find NOrton slows you system a lot, you can download AVG Free edition at

Fast and resouceful, not prone to crashing the system.

good luck

in addition:
norton might be scanning for something when you are browsing, do you have only norton or the whole system works package.

try a add/remove program and repair IE, and go to www.microsoft.com/windowsupdate to download the latest patches for IE too. (there is also for xp)
and last check on the website of nav in their knowledge base if thats a known problem.

Just try to fresh installed again.

After fresh installed, just installed NAV2004 straight away and test it.

If still the same problem, its NAV2004 causing tht problem. (maybe is a pirated one)

Or try to get NAV2003 cos NAV2004 still new in the market. (Could be a bug problem)
