Eric b Norton isnt a Hog and it isnt slowing my system down not unless you have a powerful system like i do and i have Norton Antivirus 2006.. To speed up Your system follow my Steps:
1) Start > Run > Msconfig > Startup > stop any services you dont need
2) Defragment Hard Drive
3) Clean out Prefetch folder ( Start > Run type Prefetch and hold Ctrl + A then delete and then Reboot )
4) Run Disk Cleanup Utility
5) Tone Down those Graphics to 16Bit instead of 32Bit ( Right Click on Desktop , Select Properpties > Settings , Click Apply.
6) XP Only on this ( Stop welcome screen it can get a Better Start, MY COMPUTER > CONTROL PANEL > USER ACCOUNTS it then says Pick a Task click Change the way users Log On or Off , Untick Use the Welcome Screen )
7) Scan for Viruses , Adware , Spyware etc
Your system Should be speeding up Step 6 Dont apply to Windows 98 Steps 1 . 2 . 3 . 4 . 5 they do ! good luck
