I have the Norton 360. When trying to install it tells me that Mc Afee Scurity Center needs to be eliminated.When pushing the buttom "Eliminate" Mc Afee gets only partly desinstalled. My situation is at present very ackwrds. I cannot install Norton 360 becaude Mc Afee is installed. And I cannot desinstall manually the Mc Afee Security Center because it has been damaged by Norton. The perfect catch 22 situation, that keeps me without any protection. Melchor Duran

You need to get the norton removal tool first.

make sure norton is removed. (completely)

then you should get the microsoft removal tool

intall and run that and then select the mcafee programs.

niether of those programs make it to my security listing and this is one of the many reasons why.

If you have anything that can clean the registry now is the time to do it.

If not try Registry mechanci install and run.

It may find quite a bit and take some time but thats fine
Make sure you let it make a backup.

Once thats done you should be able to install Norton 360.

There are much better products available than Norton and Mcafee

Those names are no longer as effective as they used to be and both can actually slow computers down considerbly.

Better antivirus are Kaspersky, AVG, ESET, SOPHOS just to name a few

For added protection Superantispyware, Malwarebytes, Webroot should be used. thos and the antvirus can work rogether to provide musch mor protection than the two you are using.
