Ransonware detection (cryptoguard) kills Illustrator CC 2017 performance (unresponsive)

Morning,

Go A fun one.

Issue: Adobe Illustrator CC 2017 enters a state of unresponsive upon any user action. Such as opening/closing any file, selecting tab options (file, edit..ect), moving, adding, removing images from file. Making using Illustrator useless to our user.
This issue does not effect Mac users.

Hardware: We have a single user with a Lenovo P50. Windows 10 64bit, 32Gb of ram, i7 2.7 ghz prosessor, 238GB crutial SSD

Testing:

I went through making preference changes to scratch disk, unchecking GPU performance, lowering graphics setting to no avail.

Then I shifted to Sophos Endpoint v11.5.3

Under Setting, I disabled Realtime and Internet Real Time Scanning > tested with no success > reset settings to default

Tested disabling Peripheral Control and web control > no effect > reset settings to default

Fix:

Then disabled Ransomware Detection (Cryptoguard) > tested...Once this service was turned off, Illustrator opened without issue. The application, file, or making any changes changes to the file made Illustrator not once go into a state of unresponsive.

Workaround:

We have created a Sophos Central policy to disable this service only for this one user

We are waiting for a permanent fix for this issue.

Thanks

Shane
