cannot install windows updates

I don't really know how to explain this as I wasn't at the computer at the time this happened but. I went to get onto the computer and noticed my wallpaper and IE home page was gone. The home page was replaced by some secure32 address that left it at a blank screen and had locked out my ability to change the homepage. I ran ad-aware, spybot, ccleaner, bitdefender, panda all in that order i also took the advice and did a normal startup in boot mode. I was relieved to notice that I could finally change my IE home page back to it's former setting and that I could finally surf the internet in normal mode again, however there was another problem.

When I first went to take care of the infestation I also ran Windows Defender it came back with no results. So I went to Windows Update to attempt to install the latest definitions to try again. And it kept rebooting the PC everytime the Windows would go to install the definitions. When I later did my counterspy scan it registered a large reigistry infestation. My current situation is this. Everything is working fine and I can perform normal computer tasks the only thing I cannot do is install Windows Updates because the PC will do a hard re boot. I am getting ready to attach all logs as I've completed all the Read and run me steps. I even included a Hijackthis log if needed.

 

...and the rest of the logs...

 

ok heres the updated logs. Soory about the getrun and shownew things i didn't realize they had released updated versions...

 

yep, the file is gone. should i try to download from windows update now?

....nevermind i tried to download from windows update and it rebooted saying "the system recovered from a serious error."

 

This is the technical information it printed out on the BSOD page.

***Stop: 0x0000008E (0xC0000005, 0xF4CFF60A, 0xF1FFDA20, 0x00000000)
***system32:lzx32.sys - Address F4CFF60A base at F4CFD000, Datestamp 45b0938b

Now out of curiosity I looked at the system32 folder in C:\Windows and I couldn't find a lzx32.sys file. I didn't touch anything I merely looked. I thought that might be useful information.

 

Ok, the definition is installed and Windows Defender should be up to date for now. Looks like it's smooth sailing from here. The Windows Update problem is gone, I was wondering what is a good replacement for Windows Defender? I was looking through some of the threads what about AVG antivirus and how will it interact with Avast antivirus?

 

Well heres the complete list of anti malware programs I run. I don't have any set formula or protocol I run most of them when it's time to do a scan and a few are on their way to being phased out.

Ad Aware
Spybot - S&D
Avast Antivirus
Windows Defender (judgement status pending)
CCleaner
CWshredder (being phased out)
SpywareBlaster
Windows Malicious Software Removal Tool (no longer used)
ZoneAlarm (firewall, not Antivirus)
Panda (online)
Bitdefender (online)

in adition to these I have the other tools required by the preliminary Read and run me steps and those recommended to me. However I only use those programs like Hijackthis and Getrun when told to do so otherwise I leave them alone. What I wanted to know was if you had any suggestions for me to improve my list because I was curious if there was anything else I could do to imrpove it.

 

Just one small question. How come windows security center no longer can see that Zone Alarm is running. ZA is working perfectly but for some reason security center can't see it.
