My processor is very similar to yours AMD Athlon 2400+ 1.66Ghz. I have more RAM 1meg but have Windows XP Home Edition SP2.
I use Comodo Firewall Pro (freeware)
Avira Antivir antivirus (freeware) as well as running 24/7 I do an added manual weekly scan myself.
Comodo Boclean (freeware)
Spyware Blaster (freeware) I use these as real time devices and they are allowed on my start up list.
You can also download and install a freeware program called Autoruns (links found on these forums) and check what is running on your PC against the list supplied here at BP.Com
I also have AVG AntiSpyware (free edition) and Super Antispyware (freeware) installed on my PC but these do not run on start up. I use them manually on a weekly Rota basis updating them as I use them. I have also had installed Spybot S&D 3.5 (freeware)and AdAware 2007(freeware) but found I had problems with the new version of Adaware it conflicted with Boclean (I think) and as Spybot never ever found anything on my PC due I believe to the effectiveness of AVG and Super Antispyware I uninstalled them both.
I use Firefox as my browser and use the Adblock and No-Scripts add ons for added security.
Once every couple of months I defragment my hard drive and then use the Free Windows Live One Care PC scan.
I prefer to run the Spyware scans manually as I believe the less security stuff you have running at start up causes less conflicts. If like me you stay away from dodgy sites and peer to peer programs you should not find much. my weekly scans now have at most 1-3 tracking cookies which have managed to evade my security settings.
I am very happy with the above security measures and have never had a serious problem with them. I have tried most of the freeware on offer here from Firewalls to Anti Spyware and have found that the above works best for my machine and peace of mind.
Something else I should have mentioned is that when you do a manual scan with any of the above programs then switch off BoClean temporarily. I found it tended to crash my PC if I left it working while I scanned my PC.
