yes both those are good . and i use this to back up all others
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.
