Did you know that Windows XP needs 256 MB RAM
for decent performance. Norton Internet Security comes with firewall
& antivirus ,so definitely your system will slow down, also you got
another application running & monitoring always (Spy Sweeper).
I definitely suggest a RAM upgrade. Add another 256 MB RAM.
If things didn't slow down as much with these apps , then
there must be a virus in your System. You can try formatting
your harddisk and installing Windows again. Even if it doesn't fix
the problem. Your only option is upgrade!!
