Can someone here recommend a freeware adblocker

[Coyote_Bandit]

that works with Internet Explorer and Vista?

1. No but there are other strategies

Your router most likely has a log function or activity monitor. Look at the logs and start blocking the obvious ad domains at the router.

2. Is installing Firefox or Chrome an option?

If so, then there are lots of ad-blockers, like Adblock Plus ( http://adblockplus.org/en/ ) available.

3. IE7Pro will do it...

It has quite a few excellent options for IE (not just 7)...

Here is the tutorial on the built in ad blocker:
