Sophos Antivirus question on disk usage

jim80z

All,

I have just installed your Mac Antivirus product. I was running scans on my machines internal hard disks (except the bootcamp disk) see below for config. Every now and then it looked like Sophos would take its time on a large file (a gut feel) on the raid pair which I use for video editing storage (so there are a few large files). While it is handling the large file, it looks like Sophos starts to chew up a large amount of storage on my boot drive (boot disk normal space used = 57GB, when sophos is handling a large file it can climb to ~150GB used) and once it gets over the file its scanning it releases the space on the boot disk.

Is this normal? Anyway of stopping it, maybe a setting? What happens if the boot drive fills up?

Thanks

Jim

Config : Mac Pro (late 2010) 12 cores 2.9GHz, 48GB Memory, Boot Disk 200GB SSD, Data Volume 2 x 2TB Caviar Black in Raid 0, 1 x 1TB for BootCamp etc etc

    Hi Jim,

    What's happening on those scan "delays" is that the scanner has encountered an archive and is decompressing it to disk to scan the contents.

    You can stop this by disabling "scan inside archives and compressed files".  This will mean, of course, that you will no longer be scanning inside archives and compressed files -- but it will speed up scanning and decrease resource usage.

    Agile,

    Good to know. So really after the first full scan I can switch it off unless I do anything with the archives of add any new archives (but this will be scanned by the realtime scanner anyway). 

    Thanks, good outcome.
