I like the software on the site which Manya posted...

I know that it found some stuff on my computer because I had read about such items as " flyswatter, gator, and comet cursor" being spyware,,, and I had downloaded a couple of them ( years ago)....it found 142 objects...

Here are some of the things which may come up ....

When it says close all windows programs .... hit the buttons--control-alt-delete at the same time.. that should give you a list of what is running.... highlight one of them at a time... and click on the ' end task' button on the screen...
You may have to do it one at a time.... it may give another screen which says,,, this is busy, etc... and you can click on the ' end task now' button...
There are several you do NOT want to stop running... Explorer, find fast, systray, are three of them.

When the site asks you what you want to do.. like open there , etc... pick the ' save to disc' option... and let it send it to default.. which should put it into your programs file...

then let it download .... put an x into the box for ' close when completed'.... it said three hours download at first... but did the download in about 10 minutes...

Then you can close the box on the screen and go find the program you downloaded... in your program files... and click on it... it will then start the ' install' box... and you can follow instructions from there... it is named something like "aa_6"
Read the help section before running it...

When it gets through installing you can close the window... it will have made an icon on your desktop to click on to start it....

Be sure to find the part where they say " make a copy of ".. so if there is a problem you can send that to them....

I only deleted stuff I KNEW was spyware.... the ones I mentioned above... some stuff I left to research closer before I delete it...
