SophosScanD process consuming up to 95% CPU

Pelagus

Dear,

After downgrading my MacBook Pro from Mavericks back to Snow Leopard, I re-installed Sophos Free AV. It seems to work well, except that a SophosScanD process is almost constantly - with short intermittents - using up to 95% (on average, sometimes even more than that) CPU and heating up my machine. I have completely uninstalled and then re-installed the product, from your website, but it keeps happening.

Any ideas? Please let me know if you need more information.

Regards, Hans

And yet, SophosAntiVirus pops up in %CPU as 85 - 99% CPU every few seconds. Its running from root. If I were to try to kill the program and restart it, which process would I use?

    You should see log enttries related to updates every few hours. For example, my own log says "Checked primary server at 11:51 on 17 June 2015" and prints something similar about once per hour.

    You can see active processes by running Activity Monitor. You need to switch its view to show "All Processes" (it defaults to showing "My Processes"). Look for entries that start with the word Sophos; there should be about eight of them. You can force SophosAntiVirus to quit using Activity Monitor.

    From your description it sounds like the installation might be damaged. You can re-run the installer to attempt repairs.
