Recently, I experienced system crash. Still dont know what caused it.

I use Kaspersky KIS, when I press 'block all network activity' it doesn't, for ex utorrent still works.
I suspect my system is compromised.
How to test firewall? What is the best tool or online service?
I dont know much about network, so is there something for average user.

My box crashes about once a month, it's on 24x7, I don't worry about, as I know nothing is bug-free.

Now if you are worried about being compromised, no virus scan will catch everything, and no firewall is perfect, they are just there so at least you don't make it too easy for the bad guys, and at some point, somehow, you are going to contract a malware, it's just matter of time.

I suggest instead a regular back up procedure, Windows has a built-in, saves "checkpoints" so if you suspect trouble, just restore to that checkpoint, is like a time machine, then you don't have to spend any time on it figuring out what's gone wrong.

Yes, you asked how to test a FW. If you have to ask, you don't have the resources to put it into action. Plus...
