Unwilling to pay the unreasonable $$ required by mcafee for my three home PC's. I am trialling the avast virus tool. Running it in parrallel, it seems just as good as macafee, although not quite so complete.

 

However, I'd like to keep the Macafee installation there, incase I want to revert, and avoid the hassle of updating the program and virus files from a clean install

 

Thanks
