answer:Attrib.exe is a small program included with DOS and Windows. It allows you to view and change the attribute settings of files. All files have certain attributes. Those attributes are Archive, Hidden, System and Read Only. Normally you don’t have to worry about the attributes settings but occasional you may need to repair something or remove it. While googling i found that some malware cloak themselves as “attrib.exe” If ths is indeed a missing registry error then you need to install freeware program called CCleaner and run the “ISSUES” tool in ccleaner to solve this problem If the problem still persists you might have to manually delete this attrib.exe from registry using “regedit” but i would recommend it to advanced users only
