I have a loan MacBook (from John Lewis's - how's that for service) while I my iMAC is being repaired. I have restored my latest Time Machine backup and was up and running within the hour with one exception and that was Avast. It is refusing to kick off scanning emails as they arrive and hanging the mail system so I decided to delete it and reinstal and therein is my problem.
I had already dragged the Avast application to trash when I remembered the business about turning off persistance before doing so. I reloaded the latest version and installed that. If I try to manually launch it now it says : Virus Engine cannot load, contact support so here I am. What should I do to get it all working again as the process of receiving emails is a real pain.
Hallo,
1) you can just go to email preferences, rules, and disable avast rules - then, mails will be received directly and the problem might be gone.
2) persistence - something's still in your launchd's plist. install avast from the package, and turn persistent mode off, to get rid of those avast-related lrecords.
3) engine cannot run is strange - has nothing to do with launchd/plist/whatever, but with user-id. but also, re-ionstallation should restore your structure in your home directory, and avast will start.
regards,
pc
