When I boot my external hard drive (J), a new cd drive is created (I) which is infected with Tojan.dropper.
I'm currently using Windows XP.

When i explore the new drive - it has 47 mb of files and symantec finds a virus. The infected file " SwitchFK.exe" found in
I:Driver\SwitchFK.exe cannot be deleted, unlocked, murdered, or reasoned with.

The folders on the newly created I drive are Driver, Mac X, PushButton Backup Users Guide, Redemption and about 50 misc files mostly .dll files.

Symantec cannot delete or access the file, nor can SuperAntiSpyware.

When I close my external drive - the infection goes away.

When I scan My "C" drive, the virus is not found.

The external drive has all my back up data from my C drive.

Any thoughts on how I can get rid of this virus and is all of my backup data in jeopardy?

Is this by any chance a Toshiba external drive? This may be a false positive from a program called OnSpec.

If this is what I think it is then it exists to allow password protection (and possibly encryption?) of the main partition.

Acomdata sell drives that offer password protection and push-button backup so I'll have to assume that they are using the same system as Toshiba. Nothing to worry about.

Have also noticed that there is now occasionally a flashing disk by my cursor.

but if its ok - why is symantec picking up a virus?

Have had this external drive for about two years and this problem occured right after I had some virus issues on my C drive.
