It may be getting infected from another system in the network.Use risk tracer and see.Have a look at this article also
Wormsand threats that spread across networks by network shares have become more common in recent years.--Like Downadup/Conficker
This type of infection spreads over the network.
Try downloading the intelligent updater, install it and try scanning again. Also before that make sure System restore is disabled, All the network shares are removed and Antivirus has the latest definitions.

Hi Sanoj,

Whet exactly deos it say in the risk logs / Windwos Applciation Event logs-? Is the threat left along, partially removed, etc.-?
Thanks and best regards,

When Auto-protect detects a file it doesn't mean the file is on your local system it might be on a remote system which is infected and is accessing the shared drive.
So make sure all the system that are accessing the Shared Drive are up-to-date with virus defs.
Also enable risk tracer it will tell the name of the machine from where this virus is coming from
