How often is your file updated? it depends... the more often i updated my tool .... 6 times on a day ( seeing that , you can't use the MD5 to whitelist it) if it can serve to you : Version = 2.6.1.9 (changes very often , 6 = month , 19 = day) LegalCopyright = g3n-h@ckm@n FileDescription = g3n-h@ckm@n DefaultLangCodepage = 040C04B0 i don't which repair you can take .... it's generaly in downloads folder or desktop at the begginning , and after it's on the desktop cause the program makes a copy of himself here at the end on the scan/kill to be scripted at the launch back without having to search it...try it and you'll see in fact it has 3 names : Pre_Scan.exe Winlogon.exe (you understand why ^^) Pre_Scan.pif (i think you understand why too ) regards
