    Hi,

    I installed new AntiVirus software on my mac and now when I try to start all I get in a flashing Apple logo, behind a flashing No Entry logo behind a flashing ? Symbol.

    I've put a link to a YouTube video showing it below.

    Have tried all the reboot procedures to no avail.

    Nearly there

    So I've now re-installed my operating software and not lost any data which is great but the mac keeps crashing, in particular when I either try to perform a Time Machine back up or when I load Mail. I am using the machine standard apple mail client.

    Any suggestions as to what to try?
