Windows Firewall Service not working (No Firewall will work on my computer)

I'm not sure if this is the right forum, if not please just move and accept my apologies.

Also, apologies in advance for the long post, but I thought it best to write as much info as possible so hopefully any kind soul that takes pity and helps me out will have some info to go on. (I'm sure I've missed all the important info, but I'm not super tech-savvy)

OK so here's my problem,

No firewall will install on my computer. I used to have Comodo running and it was grand until a couple of days/week ago it was telling me that there was a problem with the installation and would I like it to fix the problems, I obviously said yes, I then get a message saying it couldn't fix the problems. (It made a log of the problems with I've hopefully attached at the bottom of this post). I don't remember the exact day it stopped working, so I can't say if it was X, Y or Z update that caused it unfortunately. Sorry.

So I uninstalled, re-DL'ed the latest version and tried to reinstall it fresh, same problems, it installs does all it's scans and when I re-start the computer to finish the installation the exact same problem comes up.

So I tried Zonealarm, this time it wouldn't even install.

I then read up here and through google to see if it's some widespread problem, but I couldn't really find anything.

So I thought it may be some sort of Virus/Malware or something so I followed the instructions in the sticky here (AVG wouldn't let me run comedian, siad it was a trojan or something so I didn't run it... I was worried it might have been corrupted as the post is kinda old and I know that no-one reads stickies on boards :rolleyes: and I thought it may not have been reported before now)

I already have Spy-bot, AVG 8 (just got 8.5 tonight) ccleaner all of which I've always ran regularly so I didn't really think it was one of those, but you never know.

I also ran Malwarebyte and SuperAntiSpyware and they both found nothing.

I have Vista 32b and it's upto date. I also tried booting from the CD and asking it to repair Windows but it says there's nothing wrong.

From the various bits and pieces I've read and done I read it may be some driver conflicting with something and there are various Network Adapters that can't start and for some reason (no idea how long for, but they've never interfered with anything I've noticed in the past or now, apart from possibly this issue) I think it might be my Display Driver (so again I tried to update it, but it won't automatically update it for some reason, I DL'ed the latest driver from nVidia and it won't manually update either).

Basically I'm hoping there's some fix that doesn't involve re-installing a fresh windows.

If you've made it to the end of this post thank you in advance, and is there any other info I need to post or anything I need to do to get info that y'all need to work with.

Thanks,

Ste
