When run W32/PrsKey-A attempts to copy itself to the location:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
SpyEx
"Program Files"\Common Files\Winllogo.exe

Once installed, W32/PrsKey-A will begin keylogging information and store the logged information to the file C:\text.txt. This file is harmless and can be deleted.
