Thanks, I did just that at download.com.  It worked well.

Ad-aware removes a lot. I like it.

Go to: http://www.lavasoft.de (WARNING: "lavasoft.com" is some kind of pr0n site. Be sure to go to "lavasoft.de".)

Look for downloads of the FREE version. It's easy to set up. It has help files, and connects to their website for more details.

You can purchase additional capabilities.

lionseyes,

A useful second freeware program (which detects things that Ad-aware misses, and conversely) is Spybot which you can download from here.

After your system is Clean of spyware

Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly

I just downloaded the adware/spyware remove software. My computer is running so smooth and fast that I feel like a fish swimming up stream. And no more of the darn user.exe errors. Woo-hoo, I am a happy camper! Thanks to all of you that are so knowledgable.
