Unknown file on my desktop

... no thanks.

 

Try
Right Click, Get Info, then look at the bottom and see what the permissions are, reset so you are the owner. Then delete.

or maybe do this

Open terminal and type in

cd ~/dekstop (hit enter)
ls (hit enter)
sudo rm filename (hit enter)

file will be gone.

No, it can't be a virus. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.

Unkown file on my desktop

I have exactly the same issue.
The file appears on the desktop screen but not in finder
It will not open and asking for properties does nothing.

I tried the "sumo" cmd and got "no such file or directory"

Irritating...

 

There is no "sumo" command.

Copy and paste this command line into a Terminal window:

Code:

ls -la ~/Desktop

Then copy and paste the complete output, and post it here.
Identify exactly which file is the problematic one.

I have exactly the same problem. I get this output:


ls -la ~/Desktop
Last login: Tue Aug 14 12:06:04 on console
Dr-Stephs-Macbook:~ stephsaur$ ls -la ~/Desktop
total 1016
drwx------+ 13 stephsaur staff 442 Sep 2 22:35 .
drwxr-xr-x+ 32 stephsaur staff 1088 May 6 13:11 ..
-rw-r--r-- 1 stephsaur staff 0 Aug 27 2008 .localized

{I erased some listings in here}

-rw-r--r--@ 1 stephsaur staff 171 Apr 11 2011 ~$Anwesenheitsliste MMV und MAV.xls
Dr-Stephs-Macbook:~ stephsaur$

The line in bold and red is the file we are talking about. never seen anything like that nor had a file by that name. Now what?

PS: I erased the other listings of files in between that I was able to recognize on my desktop.

 

This is some Terminal commands to delete the file. Note that this will permanently delete the file and you won't be able to recover it unless you get it from a backup elsewhere.

Code:

cd ~/Desktop
sudo rm MMV\ und\ MAV.xls

 

I tried it, that's the output I get:

Dr-Stephs-Macbookesktop stephsaur$ sudo rm MMV\ und\ MAV.xls

HA! Never mind! I restarted my computer last night and now the file is gone, no wonder it was unable to be found. Still, pretty scary if there is a file sitting on your desktop that can't be erased, opened, or moved around.

 

That filename looks like a temporary filename associated with Excel.
