Getting Windows Update Error 8007090

I've been trying to download 4 important security updates they include

Security Update for Windows Vista (B967723)

Update for Windows Vista (KB970430)

Update for windows Vista (KB972145)

Update for Windows Vista (KB979306)

What should I do about this? They won't download and it keeps giving me a

Windows Update Error 80070490. Should I use system restore, will that work.

I've scanned my computer with norton and no problem were found. I also used

the Microsoft Malicious software removal tool and scanned Windows defender.

Any suggestions? Computer seems to be running fine. Please Help. Thanks.
