What could be keeping my antivirus program from working?

I'm sure I've had a virus here and there. My virus scans usually turn up nothing, but on occasion it finds something. But my system has been running pretty good for over a year now without any serious issues.

I did the sfc/scannow and it says it didn't find any integrity violations.

I'm not sure why you wrote KB947821 - am I suppose to do something with that?

Hi Kuurt,
that KB is a repair tool.
Hopefully it will reinstall the MS folders.

Classic Malware operation to remove certain files so that you cant update/run AV's
thats why i asked.

note
allthough as and when the offending files are removed by antimalware programs
THEY DO NOT replace/reinstall legitimate entries removed by it.
Thats why a asked about the disc, get it back.

I've been running KB repair tool for over an hour now and it doesn't seem to be doing anything either. It just says "searching for updates on this computer". I wouldn't think it would take this long surely.

Are sure I'm missing important windows files? the sfc/scannow said it didn't find any integrity violations.

And if I do need to get the windows 7 disk, would I just do a repair install?

Hi Kuurt,

The Additions.txt file from farbar was showing the missing files.

That KB will try and restore them, sometimes actually takes 2/3 hrs depending on whats missing..

and yes if that KB doesn't/can't restore them it would be a repair install.

Ok, I let the KB run for several hours but it doesn't seem to be doing any good.

I got the Windows 7 disk back from my brother but I forgot that my disk drive wasn't working. Is there anyway I can download it from Microsoft or as a torrent? I have my product key.

I did a system restore to an earlier date. And now my antivirus (MSE) is working again. Earlier in this post I did a Farbar scan and Torchwood told me the Addition.txt was showing missing files probably due to maleware. So now that my antivirus is working again, I figured I would do another farbar scan to make sure the missing files have returned. If someone could tell me, I don't know what to look for.

The previous Addition.txt is in #5 of this post.

And here is the latest Farbar scan results:
