As an answer to the RadLight Media Player threat, PepiMK Software has written a small program to protect files against deletion and changes. Download (200kb): http://patrick.kolla.de/software/files/fileprotector.zip Unzip this file until any directory, and run the included program. You'll see a new traybar icon. Right-click on the icon for a popup menu. Select 'Setup' and a dialog will appear. Add files to be protected from the explorer using drag'n'drop. Add all Spybot-S&D and/or Ad-Aware files using the menu. Toggle checkbox if you want it to be run on every system startup. These files are now protected from deletion or changes. Left-click on the traybar icon to pause or resume protection (for example if you want to update the include files / reflist). You may notice that the dialog title and the title in the taskbar are looking funny - many numbers in it. This it to prevent applications like Radlight Media Player to detect and terminate File Protector. This is version 0.0.1. There may still be some bugs, but my first tests on 2k & 98 showed that Ad-Aware files weren't deleted any more (neither program files nor desktop icons/startmenu items) upon installing the RadLight Media Player.
