SiMoNsAyS Posted July 26, 2004 Posted July 26, 2004 And I can't see why windows wants to protect screensavers as a vital system file.yes, windows .scr files are protected. prove it deleting for example ssmarque.scr and see how it is restored seconds later.and yes they are vital system files. why?? because if i'm a "bad mad ugly person with intentions to create a virus" i will choose to replace ssmarque.scr with my .scr file this will cause that my exe code can be run if this screensaver is activated.if you want to delete system protected files you will need to replace the .dll change the registry setting, delete WFP files, replace dll with original and change again the registry setting or your system will be vulnerable.

Alanoll Posted July 26, 2004 Posted July 26, 2004 actually, if you use modified DLL, either one, if you reset the registry entry to it's default, WFP will be reenabled. There is no need to replace with the original. The only difference is in RaveRod's hack, the key is changed, in the nLite hack, it skips the portion that resets the key.
