I would recommend you to use PEiD, a program which analyses your PE file and checks if it's encrypted. From there, you can make a Google search and find your solution.

You can download PEiD from www.PEiD.tk

What did i do wrong?

You should do:

code:

---

> cd "C:\Documents and
Settings\USER\Desktop"
> upx.exe -d "File.exe"

---

Edit: Replace File.exe with the name of the file you want to decompress.
Edit2: Are you currently signed in to Windows XP as the name "USER"? Otherwise change USER to the user you are signed in as.

code:

No, I'm just using it as an example.

You should do:

code:

---

upx.exe -d "screenscrew.exe"

---

instead of:

code:

---

upx.exe "screenscrew.exe"

---

code:

---

C:\Documents and Settings\USER\Desktop>upx.exe -d "screenscrew.exe"

Should i just leave it?

The file was not packed by UPX (as Eljay said) so download PEiD and find out what method was used to compress the file. Read my previous post for more info.

Now what?

Google it:
