Avast seems to be one of a few antivirus applications out there that support the Windows xp pro x64 operating system, and it's free. Although you still need to find a compatible firewall. AVG is good and I think it also has a firewall. As an XP x64 user I have found Comodo internet suite seems to run the best as far as resources and ease of use. It also has a built in firewall and is pretty much "plug and play" in that you basically install it and let it do its job. Everything from scanning to updates to firewall rules has already been done for you, but these are trivially easy to change from the Comodo control panel if you so desire.
Unfortunately, there is no "best" anti-virus for any operating system. Everyone may have a different opinion on which is best, but when you come down to it no anti-virus program is 100% efficient at combating viruses. Sometimes it is necessary to run multiple anti-virus programs or scans to get enough overlap to be sure that the system has not been infected.

I have seen BitDefender doing an extremely good job on both Servers and workstations.

The best antivirus is Kaspersky look here http://www.best-antivirus.co/
Panda is a good anti-virus.
Windows 7 Home Premium is one of the newest software. But it is not the best. Windows 7 Ultimate is currently the best software. You can access more things with Windows 7 Ultimate than Windows 7 Home Premium.
It is probably windows 7 home premium
If you are running Windows 7, then Microsoft offers a free antivirus program that is probably the best you can get. If you are running an earlier Windows system, then AVG is your best best. If you are running a Mac or Linux laptop, then no antivirus software is needed. dorothy.wilson8081@yahoo.com
windows 7 ultimate is the best, if you do not need XP mode and different language in windows 7 , win 7 home premium version will be a good choice too
For all Windows computers, I recommend Microsoft Security Essentials. It's an antivirus program made by Microsoft (the same company that made Windows), so it works great with the features and the software in Windows. And best of all, it's free!
Bull Guard Antivirus software is compatible with Windows operating systems, such as Windows 8, Windows 7, Windows Vista and Windows XP. For more information, the best place to try would be the official website of Bull Guard.
Avira is considered the best free software (free-av.com).
Personally I would say it's Windows 7 Professional. Mostly because it's more of a "stripper out" version of Home Premium and has pretty much everything that Ultimate has.
One of the best anti viruses that you can get is Kaspersky Internet Security. It comes with a lot of actually useful features, and unlike programs like Bit Defender, it is not cluttered with useless bloat. They are also the best security researcher on the planet in terms of discoveries. http://usa.kaspersky.com/products-services/home-computer-security/internet-security If you want something for free, check out avast. http://www.avast.com

Linux does not need antiviruses. It doesn't as much as windows, but it is possible for you get a virus on this system. Avast has a version for Ubuntu and its branches of distros. http://www.avast.com/linux-home-edition
