SP3 will not install

Trying to update to SP3 from 2. Mircosoft site checks for the latest updates for my computer. It then goes to install and comes back with "Windows Genuine Advantage Validation Tool (KB892130)
Update for Windows XP (KB898461)".

I go to update history and there is an extensive list of items that have failed.

Not sure why they won't install but it will not allow microsoft security essentials install either. I am assuming these are related. Thanks in advance for your help.

I suggest, you start new topic in "Am I Infected?" forum.

I did just go through a bout with the malware section. I got a clean bill of health. Should I still go with the new topic there?

I wasn't aware of your topic there.
I just looked through it and I'd suggest, you PM elise025 and ask her to reopen your topic.
Between not being able to run Combofix, installing any AV program and problem with SP3, I suspect, something is still hiding there.

Will do, thank you.
