I read some more about this vipre.
Yeah... deny access? No problem. How about I just delete the whole thing for you? That'll fix it good
Not too many people in the real world too happy about THAT undocumented feature.
XP has a built in firewall you know, and opinions on its effectiveness are far and wide.
I think most people will agree that some kind of firewall is necessary, and the Windows firewall is probably adequate for the average user like Jose.
If you are compelled to choose another free or paid firewall that has more configurables, it may not be a good idea to run the Windows firewall at the same time as your other firewall since they may get in the way of each other. Maybe things will be fine, maybe not, so you may end up having to choose one or the other.
You should be running at least the Windows XP firewall at a minimum.
