Hi Dave, Mike. I went to get the Bit Defender Free Version 10 but it kept taking me a link for the trial version of some similar software. But the following link, after searching Google took me to an actual link for the version you are talking about, on the site File Hippo: http:http://www.filehippo.com/download_bitdefender/, I hope it takes you there. This same situation took place with Super AntiSpyware Free, but if I continue to use the legacy version I am using, I will, so they say, always be able to get the spyware definitions, so far it's working.
I suspect that Avast will probably continue supporting Win 2K because it runs programs akin to XP. So if I continue to use a Microsoft OS, I will either try Bit Defender Free 10 or Clam Win, or just begin again with either Win 2K Pro SP4 or Win XP Pro SP3, then continue using Avast or just completely change to a Mac, which is increasingly becoming more intriguing. Then no more virus worries, also the most stable OS I have ever seen, rarely if ever crashes, much more innovative than any Microsoft OS. Thanks, Ken.
