Free cleaning up software for windows

Win32.Mydoom.A is a worm spreading via e-mail and the Kazaa P2P file sharing network. The worm has been distributed as 22,528-byte, UPX-packed Win32 executable and may be included in a ZIP archive.
This utility is for cleaning a local machine from the Win32/Shimg.Worm. The tool will search for and terminate any worm processes found in memory.
It will then scan all drives on the local machine and, if the worm is found, will fix any modified registry keys. It will also remove datafiles dropped by the worm.
NOTE: Certain files may be renamed by the cleaning utility. In addition, files may be "locked" by Windows and a reboot may be required to completely clean the system. To prevent data loss, all applications should be closed before running the utility.

mIRC stores all loaded scripts in memory . Therefore, it is useful to make at least scripts intended for releasing as small as possible to minimize their memory fingerprint.
Manually this is a nightmare. Removing all starting spaces, comments (good programmer has one comment for approximately every five line of code), blank lines... That is why I made ScriptCleaner, a small program for cleaning up scripts.
