Hello
Have recently tried to download and install the free version of AVG ANTIVIRUS for my mac.

Upon installing, I keep getting the following message

MacKeeper security software is already installed on your machine. AVG AntiVirus can not be installed due to the risk of interfering.

I have scoured the mac for any and all signs of previous antivirus software, and have found none.

Can you please help

Regards
Alexis
