http://housecall.trendmicro.com/     free scan 'seems to me' best now for finding almost all malicious crapola in one swoop
 i used to have 8 programs to search for spy/mal  /grey wares  , each would find it own things but never found all in one program . 
then came Ewido,  best in the bus'.  they teamed up w/ AVG antivirus .
 i now use AVg along w/ spybot and malwarebytes and it seems only the most updated stuff will affect me.
