What Warning From McAfee?

In reply to: multiple firewalls

1. To detect the number of firewalls running, verify which programs have firewall options and check to see if they're displayed in Task Manager.. One simple suggestion is to open the Control Panel, double click on "Windows Firewall" and see if it's turned ON.. If so, and if you have the retail version of McAfee with its firewall enabled, then you have at least two running. Since we known nothing about your computer except what you've told us so far, that's about as good a guess possible at this time.

2. Yes, multiple software firewalls on the same machine can cause connection issues as well as conflicts when they are attempting to block intrusion attempts.. You don't want such to occur.. On the other hand, if you have a separate hardware firewall such as one on your router, then it may not be a major issue.. Such may be recommended when there are other computers on a network.. The router firewall will help prevent intrusions from "outside" the LAN while the software firewall will help prevent intrusions from within the network.

3. The answer to this is a question: "What warning from McAfee?" The EXACT message and when it occurs would be helpful.

Hope this helps.
