Vista + TF2 + Zone Alarm == bad

Ok so I finally figured out what was causing this.

If you have zone alarm running you cannot kill the hl2.exe process.  When you quit tf2 freezes.  Then when you try and kill the process in task explorer nothing happens on the first attempt and subsequent attempts have Vista tell you "access denied" forcing you to reboot the machine to get rid of hte process (+ graphics left over from it).  Killing the process without attempting to quit tf2 normally causes the same thing.

Just thought I'd tell people as I've been getting annoyed at having to reboot a bunch :-/

I'm using the free ZA firewall.

Are you sure you've given the TF2 process full permissions? ZA can be a bit finicky about that sometimes.

FYI, I use the full security suite. I find it to be largely transparent once the programs I want to run have full system access.

Make sure you give the steam overlay client full permissions as well if you are using the Steam Community thingie.

I'm pretty sure I did but I'll check again. However, the issue wasn't that TF2 wouldn't connect or play, the problem was that when zone alarm is running I cannot kill the hl2.exe process.

Don't know if it's the same issue, but occasionally this happens to me. Usually when I forget to shut AVG down before playing TF2.
