If you're looking for a FREE XP anti-virus: 1) Avast [URL] offers a rather comprehensive program, with lots of settings for those who enjoy tweaking everything.   While it still runs very lean, the program has gotten huge (to the point of potentially intimidating novice users), and some people have experienced significant issues with it.  [Full details/discussion can be found here:   [URL] ]  So while I myself use and still recommend it, I do so now with some caution.   Requires XP Service Pack 3 (any Edition, 32-bit or 64-bit). 2) If you want a simpler program --- basically, to download, "set and forget" --- you can go with either Microsoft Security Essentials [URL]  [ requires "Genuine" Windows XP Service Pack 3] or Panda Cloud [URL]#!/free-antivirus-download [requires 32-bit XP, Service Pack 2 or 3] Stress that all of the above will replace the anti-VIRUS and anti-SPYWARE components of Norton 360.   But their free versions do NOT include a firewall (you can use the free/included Windows XP firewall), nor several of the other "bells & whistles" components that are might be part of a "complete" product like Norton 360. If you're looking for a PAID replacement, or a  "full suite", let us know, and someone can reply in that area.
I'm running NORTON 360 on my old ThinkPad with Windows XP Pro.I have decided to not upgrade to a later version of Windows due to my 2 GB RAM.I was told by a Micro Center techie that NORTON is a resource hog which might explain my performance issues.If this is true, I'm looking for a recommendation for an antivirus package to replace NORTON 360.My previous experience with this forum was very positive.I look forward anyone's suggestion.
