I think Javacool’s SpywareGuard is a very old tool and not updated anymore…
TeaTimer runs ok. But I think WinPatrol (free) will be better and more effective. Maybe just an impression.
Which firewall are you using?
In my opinion, WinPatrol is better and more flexible. I see no advantage in TeaTimer compared to WinPatrol.
Maybe some other guy could compare both and help us to have a further view of them.
For me, WP is better.
