I find all the security stuff to get way over my head, all the different types of attacks and how to know if what I have is full coverage or what. So one thing I want to know is if I am going for free versions, at least to start, it looks like Comodo has more protections than OAfree. What does Comodo (firewall and def+) and OAfree protect against that the other does not? And I like the run safer idea in OA, so, would it be good to use some parts of OAfree and some of Comodo, and what stuff from each should I then turn off as no need to have 2 trying to do same thing. And if the only thing oafree has extra is the run safer, is there something else better to use to do that (not "drop my rights" but a real program) that would work well with comodo? Thanks. (for info: i have a new Vista laptop and am also trying avast for the AV and trying returnil. of course I don't want too much resource use but just a good set-up that covers all bases like this).
