New user several questions

brvx

First, for the automatic update interval, how is the time calculated? Is it ordinary chronological time, or is it actual computer running time. For example, if I select automatic updating for daily, with the last update having occurred at 9 AM Tuesday, will the next update happen at 9 AM Wednesday, provided the computer is not sleeping at that moment. Or will it need 24 hours of actual computer running time, which might not happen if the computer is sleeping for extended periods perhaps until several days later?

Second, I ran Sophos (9.0.8) yesterday booted from a 10.6.8 partition on an external drive. It calculated something like 1,900,000 files/folders to scan. The 10.6.8 boot volume was only around 701,000. The other volume on that drive, a 10.8.5, is around 607,000, which, if Sophos was scanning both, still comes nowhere near close to the total Sophos calculated. If I add in the internal 10.6.8 volume, the total is a figure around 2,001,000, still not the 1,900,000 I saw, but more plausible. Was it scanning all three volumes? I am very puzzled about the number of files Sophos calculated. Naturally, this scan took far longer than intended.

Finally, although I logged in to my admin user in order to run the scan, I am normally running out of a standard account for security. So, of course, there I could see that my admin user was out of bounds. But from the standard user, I ran a shell script which opened Sophos with root privileges (do shell script "/Applications/'Sophos Anti-Virus.app'/Contents/MacOS/'Sophos Anti-Virus' > /dev/null 2>&1 &" with administrator privileges) When I opened Sophos that way, I was able to see the other user, but I still got the notice that I was running using "current privileges." Not sure why that didn't disappear when opened as root, but what I wonder is, since that notice didn't disappear, if running as root will have the necessary privileges needed to scan all system files, and if anything is found, will I be able to "clean" that infection--should it really need to be cleaned? I would not like to have to log in to my admin account in order to do either of those, completely scan all system files, and clean, when necessary.

    Its "clock time" not time running on the computer. Your example of 9AM Tuesday and 9AM Wednesday is correct.

    If you are scanning a whole volume, we ask the operating system for the number of files on that volume. If you select a group of folders to scan, we go count them ourselves. The operating system doesn't lie, but there are many more files on your disk that what Finder shows you. For example, the Finder normally hides /usr on your boot volume. On my MacBook Air, using the "find" command line tool, I see there are 2,9315 files in the /usr directory.

    We are running the scanning process in the background. We either launch that background process with your current privilges, or we launch it running as root. The advantage of running with elevated priviliges is the ability to see every file on disk (root == superuser, effectively) and also perform cleanup on nearly every part of the disk (there are some special cases with unique filesystems that we can't actually touch even running as root). The GUI only tries to cover the case of being logged in as an admin user rather than root (when run as sudo) so the text wouldn't make as much sense. But we don't need to have the GUI running as root in order to run the background scan as root.

    Hope that makes sense.
