Windows could not search for new update "error code 80244019"

A most effective and easiest way to fix Windows Vista Update error: 80244019 caused by or triggered by Trojan DNS changer or worm
I removed all cookies and temporary internet files from Internet Explorer and Firefox. Then I rebooted my computer in safe mode and run all the anti-virus and anti-spyware I had downloaded, and followed their instructions.
After removing the Trojan virus, I reset my DNS address and flushed it. You'll probably need "elevated" permissions...to do this you need to right click the "cmd.exe" file to "Run as Administrator" and then type:
>ipconfig /flushdns
