well exactly, its an unknown account, reported in windows as: Account Unknown(S-1-5-21-2078719863-979482418-720246454-1001)
i plan on flattening in the future, though i dont suspect anyone has access to my files.
my account is the only on my machine, UAC is on and DEP is on.
as for file sharing, i use it (i assume you mean utorrent) for linux images from linuxtracker.org, into an isolated drive where i scan them.
im not for sure, but it seems to have fixed an issue with constant redirecting in firefox. i have had this issue for a while, and ive tried doing what others who have had the problem have suggested to no avail. The only problem is that now i need to fix rundll32.exe. Any Suggestion?
im not sure where the above account is, its not in my account list, though homegroupuser$ is... and im not sure if ive ever seen it before. im currently removing all permisions that the unknown account has.
