Reviewing 184.108.40.2064 (May 12, 2015)
Windows XP (SP3)
Athlon XP 3000+ CPU (w/SSE but not SSE2 or above support)
I've been using Avira Free Antivirus for several years, but I've been experiencing minor problems with it recently (having anywhere from two to a hundred gavi3.db-related errors on my Event log at each and every start up); I reported the bug to Avira and they informed me that they've ended official support for Windows XP and will not be addressing the bug. Avira still lists Windows XP in their System Requirements, but the Web page they referred me to does indeed show that Windows XP support ended on 08 APR 2015: http://www.avira.com/en/support-product-lifecycle
As such, I've been trying out many of the other well-known free antivirus programs -- AVG, Avast, BitDefender, Comodo, Panda, and one or two others -- and Panda Free Antivirus is by far the least performance robbing of the bunch on my machine. BitDefender is pretty good while it works, but it's a bit touchy and quits auto scanning after a week or so on my machine -- though it works without a hitch (and has for over a year) on my dad's newer Windows 7 machine with SSE2+ CPU. AVG, Avast, and Comodo slow my computer quite dramatically, with even the simplest things (opening the Start menu or Windows Explorer or Notepad) being annoyingly delayed. I suspect that my ancient CPU's lack of support for SSE2 and above may be the problem in some of these cases, as a lot of newer software works better with, or even requires, a CPU with SSE2+ support, so users with a newer CPU may not encounter these problems.
I vaguely recall experimenting with Panda a year and a half ago and having problems, but the current version (15.1.0) is working very smoothly so far. Indeed, Panda has so little impact on my system's performance that it's almost like having no antivirus program installed at all: my computer starts quickly (with no warnings or errors on my Event log), programs launch/open quickly, and files open/load quickly. How well Panda is protecting my system, I haven't a clue, but it tests well in the various antivirus tests I've seen on the Web.
Anyhow, anyone with Windows XP and an old computer who's having problems with Avira might want to give Panda a try.

running latest 18.104.22.1684
something new is that it now installs .net framework 4..
Odd three updates in three consecutive business days in a row???
Higher memory requirements ? - AntiVir Free Antivirus - Avira Support Forum maybe there are some bugs being smashed by developers...
Still use it the free one. Still don't find any better than this
