Uninstalling Mcafee virus scan from Lion

I'm trying to install a Norton antivirus product, however the installer tells me that I cannot install it on my hard drive because I already have "incompatible antivirus software" installed on it, and it lists McAfee VirusScan. I had McAfee on it previously, however I have run the Unistaller provided by Mcaffee. I thought this had removed the program, however there are still clearly remnants of it somewhere on the drive. Does anyone have experience with this and is willing to help?

MacBook Pro, Mac OS X (10.7.2)

Removing all traces of anti-virus software is often difficult. In your case, you need to go to the McAfee site, not the Norton site, to search for a manual uninstall process.


Try: https://kc.mcafee.com/corporate/index?page=content&id=KB54975


However, I agree with others in not recommending Norton as a replacement. If you feel that you need an anti-virus software to detect you from no known Mac viruses in the wild, try ClamXav. At least it's free.

I ran the script in terminal window and get the message that no such file exists


I have requested and got a refund form Symantec for the Norton Anti Virus software. The ironical thing is that I am running Norton Internet Security that I purchased and installed some time ago before the upgrade to Lion


Thanks for the support

My response was to the original poster, ajham37. He is trying to uninstall McAfee, not Norton.


If you read the original post carefully, you will see that you don't have exactly the same problem.

To all:


I've found a way to take care of it for good. Go to your library folder and then to application support. Then find the Mcafee or Symantec folder, depending on which of the two programs you are running. Then simply delete that folder. This should remove the rest of the application data and stop all of the software's background processes from launching on startup. Its been a while since I've done it and I honestly forgot about this thread, but if I remember correctly, this was how I solved the problem.
