I have been unable to find help in 1) any other community forums, 2) from any anti-virus programs available (I have tried the following: MSER, Defender, Norton 360 , MBAM, Comodo, Kaspersky Labs, Hitman Pro, CCleaner, Dpy-bot S&D etc.) I have also tried seeking remote help from PCeSupport.com (horrendously incompetent), Support.com, Norton, as well as MSFT itself-all to no avail. My issue is the this. The admin profile created when PC was purchased is not allowed to access much of the application software installed. The admin profiles named CREATOR OWNER, TRUSTED INSTALLER, SYSTEM, & ADMINISTRATOR have all been given full control with inherited permissions. This was trie for 3 PCs I have just about trashed because of malware infection that seems to be tied to these admin profiles. All of the "pros" who have remotely accessed the PCs involved (there have been a total of 6) have told me that all of these admin profiles are intrinsic to the OS/registry, etc. and should not be touched. I have been re-assured that there is no problem. In many cases the PC has been temporarily fixed but has reverted to problems within 24 hours.
The usual methods of recovery, short of wiping the C:\ drive, are unavailable as system restore does not work (previosly, restore showed dates that I had wanted to restore OS to but when running restore, I'd always get error msg. restore failed, now-even if were able to fix sys restore, the only dates showing are yesterday), repair disk does not work. Other symptoms are, services shut off with less & less success in restarting, some services have been disabled completely and cannot be restarted. Late stage problems include appearance of network I've never seen named "Home 26" and not showing the 2 LANs I have created and set as default.
I think that changing permissions and/or taking ownership of files, folders, drives would help. I cannot change any of the permissions of the admin profiles in question as I have "insufficient permissions"- a common error msg. that I can often click continue to power through-but not in these cases. Another attempt I have made is giving the admin profile I originally created "full control" and "inherited permissions", the boxes for those are grayed out and I cannot change the two major permissions.
I was hoping that using the runas command, I could create a new admin profile with the same full control and inherited permission that the bad guys have.
Apologies for length and very grateful for any helpful responses. If I were to wipe C: and re-install, is there any chance problem would still exist? Ideas for prevention?
