Have downloaded and then uninstalled MacKeeper deleting from Apps/library and TimeMachine. Tried to delete trash but it said that ‘MacKeeper ATd’ was still in use. Tried searching everywhere for that but could not find anywhere. Then re-booted and trash then allowed the empty and then as soon as I unlocked to make changes the same 3 MacKeeper errors repeat ad nauseam on the console.

However have just tried with Web Shield enabled and can now connect to internet on Firefox and Safari. Eureka! Same 3 MacKeeoer messages are running non stop on console though and 2 1/2 days to get an antivirus going is a big mountain to climb.

Many thanks for your perseverance.
