Sophos 9.4 hanging on every scan

I have run Sophos Anti-virus on my Mac laptop several times now and every time it hangs half-way through the scan. From what I can tell, it is hanging on the exact same file each time. I get no message of any kind, just the progress bar showing how far along it is and the number of files scanned. I am running Yosemite on my Mac. Any help would be appreciated.

Thanks,


Darin

  • I'm getting the same problem, but it only started when I upgraded to El Capitan. Don't have any answers for you, sorry, but perhaps the moderators will start to notice. Adrian
  • Hi @Adrian Kelly and @DarinFennell. What file does it hang on? Is it the same as community.sophos.com/.../10371
  • this is happening to me as well after an el capitan update. The "files remaining #" counts down, but it keeps getting hung up on the series of files (one is open office; the other is education software). My scan got 75% done before this started, and it just took forever (~3 hours for 600000 files) and I just shut it down.
  • It would be really helpful if you could post the output of the logs, so we can get an idea of which files the scan is hanging on.

  • here's what in the log files for scan local drives:

  • basically, the scan is getting to about 75% done, then it detects an issue (not a threat) and then starts cycling through open office, a piece of education software, and google drive installer over and over. the files scanned dialogue keeps going down, but the overall scan is appreciably slower
  • they all seem to be .dmg files, if that makes any difference
  • It seems to have something to do with archives and compressed files. I've been having this problem for a long time. When "Scan inside archives and compressed files" is turned off (by unchecking that box in preferences), the scans complete in short order. But when it is turned *on*, the scans always slow down severely at about the 90% completed point. For me this was always happens at approx 610,000 of 775,000 files scanned (no file names are displayed). From that point, it would slow down to the rate of about another 1,000 files scanned every 45 minutes or so. That calculates out to approx 48 hours to finish the scan! And my fans also start racing almost continuously from then on. So I always stopped it instead.

    Trouble is, I have no idea if skipping scanning inside archives and compressed files might be missing potential threats. And I don't think it should take over 2 days to find out.

    P.S. Sorry I missed Serra's entries from December 16, 2015 when I replied here. I certainly hope engineering can fix this. It's been a very long standing issue. And yes, probably not a good idea to exclude all archives and compressed files.

  • I don't find this the problem as I don't have "scan inside archives" blah blah blah set. I got it to work, again, on the 2015 MacMini, but not the 2009 MacBookPro both running El Capitan, both running the latest Sophos. I simply added *.dmg to both. I also added "basesystem.dmg" to the latter since it is hanging on that. No luck. I have rebooted. No luck.
  • I suspect the problem has multiple triggers then. FYI, I have an early 2011 MBP running El Capitan 10.11.2

  • It cannot get past something called basesystem.dmg
