This gateway i got came with mcafee, i deleted it using the mcafee uninstaller but the firewall says its active when i check under windows security. i've looked around in regedit and didn't see anything about mcafee. so what im asking is how can i get rid of the firewall?
You need to run McAfee install program to access the uninstall tool. If you have the McAfee CD run that, or if preinstalled see if there is an instalation file on the HDD, otherwise contact McAfee for removal tool.
