My kids have been downloading again and I've got problems. Two new programs were installed yesterday - AutoUpdate.exe and winstore.exe. The winstore.exe came with four other .exe files that I deleted, but XP won't let me delete winstore.exe ("cannot delete winstore, Access denied, etc") The same is true for AutoUpdate.exe and the libexpat.dll that came with it. My browser was hijacked in the process. (Working on that with Spybot right now). How can I delete these files? The winstore.exe appears to be connected to Limewire (which I also remove about twice a week). Please help me.
