Running Immunet Plus alongside (unsupported) Sophos Endpoint Security and Control 9.


Booting from C: with Windows XP Professional Service Pack 3.


(D: has outdated Windows Vista Enterprise but I rarely boot from that volume.)


Following boot and log on to XP, a yellow shield signified an automated Microsoft Update. The shield disappeared after maybe 9% download complete, which made me suspicious.


The machine seemed to be slower than usual (blue shield for Sophos didn't appear in good time, and I don't recall seeing the Immunet Protect icon in the tray) so I opted to (a) log out or (B) restart the OS (I can't remember which I did, sorry).

no longer exists, sorry … but configuration on this machine is currently to send files to the cloud, so maybe you have it there already.



It was a detect in the Tetra engine, and a false one. It's fixed now. Thanks Graham and thanks to the other user who mailed me directly.
