to protect your system from hackers, viruses and spyware?
What type of internet connection?
I have a Dell poweredge 400sc. My operating system is windows XP home edition SP2. Recently, I have some problems with my network conection. A few days ago, the web browser became extremely slow at some point, although good at other time. But right now, whenever my network card searched for IP address, it is automatically disabled by some program. So I couldn't go online at all. I am sure the network connection is good though. What do you think the problem?
