I'll advice you this... I dunno about the "Wyzo browser" security issues , but i just started to use browser called "torch".
I didn't want a separate software for torrents' downloading and then i found this browser.
To make it short - i'm now using it and can download torrents + magnets easily and pretty fast.
so Rob if you're worried about spyware and stuff i think you should get torch instead of wyzo because torch didn't caused me any problems.
Hope i helped!!
