Thanks for the posts everyone! Unfortunately the reply I just spent the last 1.5 hours typing just got erased, so I'm starting from scratch again. Curses!

Your posts have definitely got me thinking, so that's a
good thing. But it also brings up a bunch of new questions, so I hope you don't mind!

First, some info:
*My replacement laptop will have XP Pro
*I use Firefox for all internet browsing, except for Windows Updates and the occasional Office Updates
*I have dial-up (as stated)
Questions:
1. Re:
Comodo Free Firewallversion 2.4 vs.
Zonealarm Free 6.5.737 vs.
AVG Internet Security Firewall -- Firewall stuff tends to make my head spin. I've been using
ZA Free 7.0.302, but due to the size of it (since the Pro stuff is just turned off) and it possibly acting weird (you may have seen my long thread on this), I was going to use
ZA Free 6.5.737 on my replacement laptop coming up instead. Then Maabsta recommended Comodo, so I looked at their site -- but then I saw that it supposedly has a
vulnerability that won't be fixed until the next version (if that even) -- although I don't know what any of that actually means in that thread.
Alan D has me considering just bying teh AVG Internet Security, which includes a firewall -- but how does that one measure up?
Alan D, which do you use?
I actually started a thread about this since it's off-topic a bit, if anybody would prefer to post about this item there instead:
http://www.bleepingcomputer.com/forums/topic102528.html2. Re:
SpyBot Startup List -- I looked at this and I noticed that some things listed in it are things I have unchecked in msconfig/startup and they are listed in SpyBot/startup as "Startup (disabled)". However, there are many things that I have unchecked in msconfig/startup that are NOT listed at all in SpyBot/startup. Why is this? Does it have something to do with the fact that maybe they are related to services? Or perhaps that I never downloaded the "Updated Startup Entry Descriptions" (since it's not marked as priority)? Regardless, if these items are not listed in SpyBot/startup, and I'm not supposed to turn them off with msconfig/startup, then how would I turn them off?
3. Re:
SpyBot Hosts File -- How do I use this and/or turn it on? I use the immunize -- is it the same thing? The other day I searched for a hosts file on my computer and the thing I found was blank (well, it actually just showed an example of an entry if I were using it -- which seems to imply I'm not). So if that's the case, how do I turn on the SpyBot hosts file? Or should it be on already and something is wrong here...?
4. Re:
SpyBot Teatimer -- Years ago, when I first started using SpyBot, I read that this causes conflicts or something, so I've never used it. I'm hoping that with the rest of the programs I'll be using, this won't be necessary...?
5. Re:
SpywareBlaster -- Lots of recommendations for this here. Guess I'll add it to the arsenal, as long as there are no conflicts with anything else we're discussing?
6. Re:
SpywareGuard -- It's own site says it could cause conflicts, so I think I'd rather skip it, just to be safe...
7. Re:
Comodo BOClean Anti-Malware Version 4.24 -- I noticed this while looking at the Comodo site. Should I add this to the arsenal as well, or are there any conflicts with anything else we're discussing?
8. Re:
SuperAntiSpyware -- I knew someone who installed this and it crashed their computer. But I kept reading that it's good too. So my thought is that it's not something I need, but can download/install it if/when the time comes that I have an infection (especially since the free version isn't a real-time protection thing anyways). Sound good?
9. Re:
AVG Internet Security vs.
AVG A/V Free & AVG Antispyware Pro --
Alan D, you said you have the full paid AVG package, so do you use the firewall as well? It looks like the Firewall is the only difference between these two options here, right? I'm considering paying for something from AVG, so is the whole package worth it, even if you don't use the firewall? Or is it best/easiest just to us the whole thing?
10. So, tentitively, I plan to use either AVG Internet Security (with it's firewall) or AVG A/V Free & AVG Antispyware Pro together with either Zone Alarm Free 6.5.737 or Comodo Free Firewallversion 2.4, along with AVG Anti-Rootkit Scanner Free, Lavasoft Ad-Aware 6.0 Free, SpyBot S&D, SpywareBlaster, and (maybe) Comodo BOClean Anti-Malware Version 4.24.
10a. To reiterate a bit -- Any conflicts between any of this stuff?
10b. I'm I correct in saying that even with all those things, the
only real-time malware protection is if I buy either the
AVG Internet Security Suite or the
AVG Antispyware Pro?
Whew! Typed it all in again from memory!
Thanks again for the help! Looking forward to hearing back!
