Sophos Home making Photoshop CC unusable on 10.9

tsp1965

Hi

I upgraded ML to Mavericks a few days after it came out and quickly found that PS CC had become unusable, particularly for large files. After a lot of frustration, blaming the OS and Adobe, I discovered that if I switched off on-access scanning, the problem disappeared. 

Today I noticed that Sophos 9.0.4 was supposed to be mavericks compatible, so I thought I would check what version I was on. I was still on v8, because i hadn't realised that Sophos updates definitions but not the application automatically. 'Aha' I thought 'This will fix my problem!'. So I installed the latest version (9.0.5), turned on on-access scanning and Photoshop stopped working again!

Turn scanning off and all is good again.

I had previously noticed that 10.9, Sophos & PS 5.1 play fine together -  it is just CC which has the problem.

What I get as symptoms is that when I open a file - any size file, although much longer freezes on big files - it opens fine, I can select my first tool and start doing something. A few seconds later I get the beach ball and everything freezes for several minutes.

At the moment I have opted for usability over security, but it would be nice if Sophos could fix this, please........

    Hello tsp1965,

    Do you have the "Scan: Inside archives and compressed files" option enabled in the On Access preferences? And is the verson of PhotoShop CC you are using based on Java? We have a very aggressive scanning policy for Java executables (which are archives) so when you launch a Java-heavy application with that scan setting you might find that its unacceptably slow.


    Two potential solutions: (1) disable the "Scan: Inside archives and compressed files" option; or (2) create an On Access exclusion for the Adobe application folder.

    The first option is generally safe as long as you know your archives are being scanned at some point (set up a scheduled scan). Use the second option to just avoid scanning the Adobe applications.

    Note that it seems Java isn't used in all Adobe products but it is used in many of them, so it depends on which version of PhotoShop CC you are running.

    Hi Bob

    Thanks for the reply. Really nice to see Sophos developers responding to users' needs in the online forum - puts to shame the policies of certain developers of expensive paid-for software who do not.

    I don't have scan archives checked, but in any case a little Googling suggests that the CS6 and CC Photoshop apps don't use Java, but CS5.5 and earlier do. Ironically PS 5.1 seems fine.

    I have tried disabling scanning on the PS folder itself and we'll see if that helps. But my guess is that the problem is Sophos trying to scan the scratch file created when a new document is opened, and I presume that's not in the PS app file. PS is set to use the boot drive as its scratch disk, that being the only internal drive. That's a fusion drive, which may also be relevant.

    I'll post back later today when i have tried the new settings.

    Regards

    TP
