You've not told us your operating system...or the version of McAfee you have installed? They make a VirusScan Plus, Internet Security, even the 4-5 year old VirusScan 7 had a firewall..
Most of McAfee's newer prescription models need to have a paid annual prescription for anything to work.. The older, "perpetual" programs would continue to work correctly even if the updates were stopped.
As to which programs NOD32 needs to have remove, you'll need to ask the NOD32 folks. If they're only referring to ViruScanners, then maybe only VS will need to be removed.. Then again, if you're using the newer "suite" of programs, which include SPAM scanners and antispyware tools, you may need to remove everything.
Hope this helps.
I'm switching from McAfee to NOD32 for virus/spyware protection on a Vista system. NOD32 has no firewall and things are a little thin right now in the Vista firewall department. Two questions:
Will the firewall remain functional after the McAfee subscription expires? Does the subscription expiration simply mean that updates are no longer available, or will it disable the firewall and other features?
According to NOD32 I will need to disable other scanners to avoid conflicts. If I keep the McAfee firewall, which McAfee services would I need to disable to stop the McAfee scans from interfering with the NOD32 scans?
