Just ran MalwareByes and it found and quarantined the following. I can find precious little info on The 'Net. A search of THIS forum produced nothing. Can anyone shed some light on this?

Hi and no need to panic

The folder has been seen to be created by Tracur.A aka Worm.Nugg which is very aggressively distributed on the P2P networks.

Usually it would hold archives of the worm to be shared via P2P software so it has been given the generic flag of Worm.Archive**

**This flag is used for quite a few P2P worms that create repositories for sharing itself by P2P operations so is not soley the domain of Tracur.a/Nugg but in this case it is.

The folder is created in the system32 directory for concealment(by location,name and hidden attributes) and usually the installed P2P software is modified by the worm to include this folder in its shared parameters.

The folder with no contents by itself represents no risk but is a marker that the worm has either attempted to install and been sucessfully blocked or had been previously installed but since removed from the computer and this folder is just an orphaned object.

Just to put your mind at ease here is what you would see if you had Tracur.A/Nugg active on your pc

and here is what MBAM thinks of it
