My computer was having strangely behavior .
- When i open a drive on my computer usually its open in the same window
but this time its open in a new window. - file was has no extension. if i changed it through my computer options. suddenly its changed back to no view extension.
and its spread through my network.
a couple thing i notice the thumbs.db (usually for thumbnail picture) was have extension of com
so its would be thumbs.db.com (see it through ms dos prompt)
and if i open it with editor. the inside was a program not usual thumbs. and if i delete it. it comeback create new thumbs.db.com
i search it on net. it was called Blue Fantasy. here you can find more info about it http://www.vaksin.com/blue_fantasy.htm
