installed and working. it makes you remove other supplementary security programs though. it doesn't like shadow defender or webroot. i had to uninstall them and reinstall after, which seemed to work. it's curious it didn't dislike heimdal thor. it seems fsecure has an interesting banking function (or online purchasing) where it kills all internet connections any other programs have online when you enter the banking site. maybe not the most effective, but i do like novel thinking. but this might cause some problems with heimdal, and other programs. i'll be curious to experiment with this, heheh.
and it seems light. but everything does when you first install it, so i'll have to wait a week and see if it gains a bit of weight
