Windows 7: undeletable file

hi,
i have a problem deleting a directory from my desktop.
a while ago i installed a program (wich was working fine) and afterwards i was installing another program. during this install my pc crashed and deleted both of the programs.

i couldnt reinstall the first program becouse the computer was thinking that the program was already installed but couldnt remove it either. so (maybey stupid) i cut the broken files out of programfiles and pasted them as backup on my desktop. later i was able to reïnstall the program.

but now when i try to delete the folder it sais im not autorized to delete it, however i am logged in as administrator.

i already tryd following things to delete it:
-cmd commands del filename and del /f filename
-the program unlock me
-get the ownership of the folder with cmd commands
-startup in safemode
-...

nothing gave any results
i hope someone can help me

thx and greets,
camo

Welcome!

First, check to make sure you don't have a virus. Run a scan with Malwarebytes.

You can also try this post: Folder won't Delete - ARGH

i have ran a complete scan of my pc. even used 2 antivirus programs (avast and the sugessted malwarebytes) i found 1 infected file. i made the program delete it, it rebooted the pc and when it was running again there were no results. the folder is still on the desktop and i cant delete it.

are there other methods or suggestions?
thx

Hi Camo and welcome to Windows 7 Forums

You could try booting into a live version of Linux (this runs directly from the CD/DVD, and does not save any information to your HDD), and see if you can delete the file/folder from there. You will need to browse to the folder in question. This method quite often succeeds where others don't.

great! thaks i will give it a try but im going to need a little bit of help,
where do i get linux for a cd? and how do i start it? just by booting from cd when starting up (with cd inserted ofcource)?

Here you go: Download Ubuntu | Ubuntu

Ubuntu is a popular version, that is similar enough to Windows and Mac that you should have little trouble finding your way around.

Download and burn the CD, then boot from it. When it asks you if you want to install, run Memtest, or "Try Ubuntu without any changes to the computer", choose the latter.

ok i downloaded ubuntu burned it on a CD and im able to startup from the CD.
now my question is wich option do i have to take couse when i take the one thats below i just startup windows and i cant remove the folder

do i have to take try without changes?

Yes, try it without any changes.

ok i tryd that but i have some problems with finding the folder i want to delete it seems like i cant acces the hard drive disk. how do i have to do it?

Hang on, let me boot up my virtual Ubuntu machine.
