I need security software advice.?

Thanks to everyone for advising me on protecting my lap top against viruses and spyware. I found your advice extremely helpful, and eventually went with the combination of AVG 7.5 for virus protection, and Spybot S&D and Spyware Blaster for spyware protection. If anyone has any further advice, or comments about my chosen selection I will welcome them. I would also like advice about a program called Advanced Windows Care which I have been told about. Does anyone know if this is worth downloading. I run Windows XP and have been told that it does most of the things advanced windows care does already, but I don't know enough about it to know for certain. Can anyone advise me on this. I will download it if enough of you think it's worth having, and if it will work with the security software I have installed already. I look forward to your advice.
