Sophos causing widespread system disruptions
Hi all,
I've recently rebuilt my system and thought that I'd voice my experiences in the hope in finding some answers.. Particularly pertaining to the Sophos antivirus application. Along with many other I feel that the presence of an antivirus on an OS X system is becoming increasingly necessary in today's virus/malware filled world.. As rare as they are, in my professional career I have encountered several instances where systems were compromised as a result of such infections. I'm aware there's several similar applications available; Avira, F-Secure, Kaspersky, E-SET Ctber Security Pro. I simply started using Sophos a while back and up until recently have had no reason to consider anything else.
Some basic info, I'm running my system off a 2010 MBP with 8GB RAM and 2.66GHz i7 processor. It's laregely used as a platform for video editing and audio recording wih your typical editing and recording applications.
My first problem was encountered whilst attempting to install the Native Instruments Komplete 9 Ultimate package. Under other systems running 10.6.8 and 10.8 (with Sophos running) the drive would mount and the installer open without a hitch. However in 10.9 upon mounting the drive and launching the .mpkg the installer would immediately go into not respoding and stay so regardless of how long I left it (I tried over an hour). No prompts would open nor any windows, simply Installer appication would simply sit idly in the dock. I thought I'd mention that at this point I had installed a bunch of other software on the system build and had not encountered any such issues.
I went through all your ususal work arounds, from reboot in safe mode to fixing permissions, copying the contents of the HDD locally (ruling out any problems with the drive provided by NI), went through troubleshooting with Native Instruments Tech Support as well as the place I bought the product from and it wasn't until I had rebuilt the system twice ( gahh! >.<) that I realised that it was only after I had installed Sophos that the drive would refuse to install.
Second of all, being an avid user of the various Kontakt libraries and samplers available I have also noticed that samples take FAR longer to load and initialise and open while Sophos is activated on the system. I'm assuming that can be attributed to the on-access scanner going through and checking each file.. but I may be wrong. This is irrespective of whether Kontakt is loaded as a stand-alone application, or in a host (namely logic 7 and logic X).
I realise I may not necesasrily be able to get any conrete answers but I'd appreciate hearing any ideas or even similar experiences you might have.. even if only to satisfy my own paranoia haha.
Thanks in advance!
