I've noticed that there are 2 empty folders appearing on my desktop.
I'm not sure if they are really folders, their icons just "blank" icon. I've tried to double-click, no response. Right-click, and menu with only 3 choices appeared:"Cut, Create shortcut, delete". I've deleted them, but before strange message appeared:
Are you want to delete these icons from your desktop? To restore it later, go to Control Panel."
Click "Yes" and folders removed, but the recycle bin still empty. After a while or after hitting F5(refresh) button, they appear again. Seems like virus, but I've just checked my PC with updated Kaspersky AntiVirus. Nothing found. At last I opened Desktop folder with windows explorer, clicked once on each of them and found a text like these:
::{B0FBD52D-C4A7-4A19-985D-11309D1AC8AE}
on first and ::{0875DCB6-C686-4243-9432-ADCCF0B9F2D7}
on the second "Folder".
