They are all free except for the trojan removers but you can get a 30 trial with them.

Ad-Aware SE (a scanner, download, check for updates, read the directions and scan.

cwshredder (stand alone unit)(another small scanner for certain things, ALL other windows should be closed)

Download anti-trojan (any of the following)
