Personally, I don't think antivirus software should ever be installed on a Mac for any reason. But if it is it can't be remove by click and drag but must always be removed using the uninstall procedure written by the developer. Av software puts bits and pieces everywhere through out the operating system. If removed by click and drag it leaves bits and pieces of it all over your operating system to cause mysterious problems in the future.
