Buy a New Computer. Look into the iMAC

If your computer is still too slow, this may be your only option. As the software you use gets more complicated, so do the system requirements

You may also consider an Apple Computer like the iMAC! I switched in DEC 2006 to a 17" iMAC and am LOVING it! The new Apple Computers will also run Windows.

Also, no real need for anti-spyware or anti-virus on the Apple Computer!
