Though free antivirus and spam software is not the best, it is certainly better than nothing. Go ahead and install it. You can get both here: http://free.grisoft.com/doc/1

The best way to speed up your old machine is probably to buy some ram (memory). However, if you do not want to spend money, go through your add/remove programs and get rid of every application that you do not use or anticipate using. Then delete your internet history and cookies in internet explorer, then run a defrag.
Add more memory, install good antovirus, spyware software, defrag hard drive.
