My Windows Update was working fine up until about two weeks ago.  Two weeks ago my Kaspersky ran out and I switched over to Bit Defender.  I am trying to install a new program and get the message that my Net Framework needs to be updated, there is a current Net Framework 4.0 update but it won't download.  I ran the troubleshooter and tried many other things to get Windows update working.  I get the message "Windows cannot search for new updates"  code 80080005.  My most recent check for updates was on 8/20/2013.  Checking my update history I had numerous updates up until 9/10/2013, I was also able to download one two days ago, but there are two more and they will not download.  I might add that the numerous updates until 9/10/2013 were all installed successfully, and it was not until I installed Bit Defender that I cannot use Windows Update.

No guarantees but you might like to try the following sequence:

 

Uninstall Bit Defender using their removal tool:

http://www.bitdefender.com/uninstall/

 

Uninstall Kapersky using their removal tool to remove any remnants:

http://support.kaspersky.com/common/service.aspx?el=1464

 

(Windows Defender now active?)

 

Run the MS Windows 7 Update Fixit Tool:

http://support.microsoft.com/mats/windows_update/

 

Test Windows Update functionality.

Update: I forgot to mention trying to run (from an elevated command prompt)  sfc /scannow  if my previous suggestions did not work.

It is necessary to remove that tools ?

 

 

You should only have one antivirus. An old one should be uninstalled first. If a second one is added without removing the old one, you could get problems (such as these) So, best to start fixing problems with nothing that might interfere. An antivirus can be added once your system is stable again.

Not sure exactly what you mean but whenever I encounter a problem such as yours, I prefer to recommend a clean uninstaller tool to make sure that all remnants are removed; however, the typical uninstallers may work in many cases but I thought you already tried that with Kapersky.
