In my opinion,if you have Windows XP,i suggest you get Microsoft Security Essentials (MSE). i just had 3 viruses found on my computer, and i think 2 were already infected, and it STILL could clean them. I love it. i think you would to.
NOTE: Microsoft officially ended support for Windows XP on 8 April 2014, so security patches are no longer being released for it. For this reason, if you are still using XP, you would be wise to move to another OS such as Windows 7 or a current version of Linux (or any other OS with ongoing support).
=======
MSE is still available for XP and can also be used with Vista and Windows 7 but not Windows 8 (which has built-in AV). Keep in mind that MSE does NOT cover all attack vectors. Most computer security professionals recommend anti-virus plus other anti-malware protection that can use both signatures and heuristics to detect threats. You can enable or install host-based firewalls and anti-spyware software as well. As a general principle, you should deploy several tools to cover different vectors but any protection is better than NO protection.
As far as "best" is concerned - that depends on what you are comfortable managing and what your budget is. Some software suites require more skill to effectively manage. Others are less powerful but don't require much knowledge to deploy to your computer(s). Get something that you can afford and that you feel capable of managing correctly.
