Wired?
My results are generally in the 100-150 kbs range download and 200-300 upload.
Tried Firefox - no help.

If it’s a wired connection, I doubt anyone is stealing your bandwidth. Which still makes me wonder if some other software on your computer other than your browser is using the bandwidth.

Mhhm..Someone already suggest a bandwidth bandit. I'd start there and make sure you're using WPA and NOT WEP (too easy to hack).

Try rolling back to a restore point, hopefully you've got that enabled in Windows.

A network problem with your ISP is possible, but probably unlikely if it's more than 12 hours of sluggishness.

Lastly, if you know the name of the Windows Update (should start with a KB) you could search that update along with your router name and see if anything comes up. Could be a firmware issue, but that's probably a longshot too. Sorry!
