Can't use windows update - Where can I find optional updates?

Due to a problem with BITS I cannot currently download updates using Windows Update. I can download them manually and install them from the Microsoft website. Unfortunately I can only find the required updates but not any of the optional ones. Does anyone know where I can find these? Even if I search for the update number the search comes back empty. Also, if you would like to help with the BITS problem please look at my profile to find the other thread.

Also I think something is wrong with my permissions. I keep having to take ownership of folders to be able to run the applications inside of them. Is there a way to reset the permissions? This may be a completely separate problem but it is quite annoying.

I have run malware bytes; it did not solve the problem. I am using Avast - the computer came with McAffee but I uninstalled it.

I forgot to mention that at one time I had Panda Antivirus

Is there a removal tool for AVG? I may have had the antivirus installed at some time. I still use the tune-up program from AVG too if that it relevant. I am downloading the uninstallers you suggested right now.

When I run the McAffee removal tool it says some or all files could not be removed and that it is an incomplete uninstallation.
