|First thing I would do is dump McAfee....it's just a big resource hog since you only have .99GB ram|
Avast free would be a good one to use, better real-time protection, regular updates daily and no scheduled scans, what more could you ask for?
If IE8 doesn't slow you down, that's great. If it takes a long time to open, I would suggest to revert to IE7, it is not so bogged down.
You could also add Spyware Blaster to your arsenal, it works great with all other programs.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
