Fifth fomat! so you have only just started then! LOL no seriously, I get a lot of recommendations for AVG antivirus, get the free version, it seems to run well and not chew up sys resources like norton 2005 does on my machine. As for getting that little more out of your system, without knowing your specifc settings, first up, try tweaking your BIOS settings and then also limiting what programs start up with your computer, hit start > run > MSCONFIG then go to the startup tab and see what programs are running. If you are confident to know what you need with startup then go ahead and disable items you do not need straight away. (when the computer restarts be sure to check the box on the prompt that appears as the pc starts) Also in the services tab, again if you feel confident, turn off any services you do not think you need. These are just basic tweaks to help boost your pc, if you look in the tweaks section here, I am sure you will find a whole lot more! If you get stuck, just holler.
