My Father is using McAfee Security Centre on his PC but as far as I know he's only using the antivirus module or protection and not the FW, Anti Hacker or Anti Abuse modules, as it only allows me to only update the antivirus index, so I'm not sure by updating the antivirus index am I actually updating the antivirus dat files or signature files, sorry bit of confusion here. Also when I go to My Security Index it mentions the following: Old version of antivirus software detected Moderate Anti hacker detection detected No anti abuse software is installed on your computer Also it says " the antivirus software you have McAfee Virus Scan is not up to date. Now I'm more confused, I'm getting totally mixed up between McAfee Security Centre and McAfee antivirus. It doesnt look like my Fathers PC has got any other AV software apart from this McAfee Security Centre. He does use Windows XP FW though.
