BleepingComputer.com: Opinion on Security Setup

My pc just got annihilated by the spyware.iemonster.b virus and rather than go through the lovely process of removing it, i just reformatted over it like 12 times (ancient harddrive, had to do install through DOS mostly, not fun...) and I'd rather not go through that again. I've been looking through your recommendations and opinions about security freeware and have decided on this setup:

Adaware 2008
Spyware Blaster
SUPER AntiSpyware
Sygate Firewall
Windows Defender
Spybot S&D
AVG Free Virus Scan
host.mvps (will install it)

Please tell me if any of these will conflict. I don't think they will since the only firewall is Sygate and antiviurs is AVG, the rest are just adaware/spyware/malware programs (i think). I chose Sygate because one of your moderators mentioned they preferred it, and I don't know anything about freeware firewalls. Your opinions on them are not stickied, so I could not regularly find them.

Background of (nerdily) entertaining story of Mia:
Nowto explain the reformatting problem, that was unrelated to the virus. A rather old dell with Windows XP Home Edition got infected while downloading a .exe fix (last time i do that... I'm wasting all my space on images now) but the harddrive on it has been failing for years now. Windows could not format it during installation so I went into the windows repair manager (a DOS program) and deleted the C: partition, repartitioned it, then of course "format C: /fs:NTFS" and then the install worked. I had trouble reformatting it long before this happened too. Then to top things off, the CD drive is also going so it only recognizes one install CD for Windows XP Media Center Edition from my other PC, so I had to install with that. Unfortunately, the CD key that came with my Home Edition was not compatible with Media Edition, so I had to use the CD key from my other computer to install it. Now, I do have an external CD drive and the install disk for Home Edition, but Home Edition won't let me install because it's SP1 which the computer acknowledges is a downgrade and won't let me run it. I can't boot from the external CD drive either, so I'm stuck with Media Edition.

My computer's name is Mia, she has feelings and the last few years have been rough for her. My friend and I just got her working after 3 years on the bench with a miracle "chkdisk C" command. She has been very reliable since and I want to her to be happy and safe. Will this do that? Also, if I use the windows product key from my other PC that is still connected to the internet, will that produce problems? Finally, I have not connected Mia to the internet yet because I wanted to install all of these programs previous to that, but that means she's running on SP2 and IE6 for now. I also get lots of pop-ups to validate my version of XP. I think if I have a problem I can just explain it and they'll let me go, or else they'll have to teach me how to downgrade my XP. I'm thinking they'll go with the easy way since either way they won't make money.

A lovely sob story, but seriously: opinions? I wasn't going to install anything until I have some reliable people supporting me. I will check this post as often as I can (a few times a day??) but I would really appreciate a quick response! Thank you!

I tried to use Sygate but every time I started up windows I would recieve an error that it encountered a problem and would have to shut down, and then about 2 minutes later I would recieve another error saying Dr.watson or some other program that came with it failed to initialize. I have uninstalled it and am switching to:

Comodo Firewall

I notice that this firewall comes with an antivirus, but I would rather use AVG. I assume I can simply shut off this antivirus or even choose not to install it? Also, I noticed that Spyware Blaster comes with internet protection services and that it's not actually a malware removal program but rather a prevention program. Will running these protection services with Comodo firewall create a security risk?
