error message 00000643 - dt000 when downloading an update

I'm unable to download an important update (Microsoft .NET Framework 4 for Windows 7 x 64.  I get the error message

00000643, dt000.  I tried the "fix it" from Microsoft, and it does not help.  My system has been gel, Explorer 9 closure continues, my hotmail is not working properly.  I did a scan s Malwarebyte and it did pick up a few items as did my Norton but my system is always wrong.  I'm not strong in computer science, so it's very frustrating - suggestions?

If it works fine in Safe Mode then most likely a software problem.

Then restart the laptop for normal windows in the boot, only andrun diskcleanup

Then run this fixit again if you have already run...

Reset the Windows Update components?

After restarting the laptop try to re-run the updates. If possible directly download the update from the Microsoft Download Center, just by typing the code was updated in google.
