Since the latest version of Spybot, I'm unable to do all the updates unless I go to the web site, because one of the update portions responds with a "bad check sum" message. What does that mean?

Also, on my Windows XP Home computer, Spybot is checking 30746 items. But on my XP Pro computer, Spybot is only checking 15782. Is that as it should be?

Thanks much,
Bahb
