Is this a virus?

Whenever I make a new folder, it has the name of a bird
eg
chicken, lark, hawk etc
Anyone know wtf it was?
Theres a little yellow icon next to 'New Folder' but I dont know what it is for

I see you are using Alzip for archives...i believe that program does that. Notice the icon is a bird egg? (hint)
