Ive asked this on a few sites that were more appropriate, but they keep sending me to programs to install.. when ive clearly stated, that thats impossible to do.. so heres the problem:


it started around last night, ive lost all admin rights on my admin account, unable to install or run most programs, namely things that would get rid of whatevers crawling in the dark.. ive done boot scans with avast, found a few infected files, deleted them asap, problem still persists.. went to install Malwarbytes (had it installed, it vanished it would appear) but when i did i got an error stating that the file could not be found, even though i had just downloaded it.. my system restore files were all infected, thus, cannot restore to a previous state.. ive attempted to run cmd as admin to run a sfc scan but to no avail, it opens cmd as normal, but cant open it as admin, when i select to run as admin it tells me it cant find the program, but it runs just fine as non admin.. "Windows cannot find 'xxx'. Make sure you typed the name correctly, and then try again." I have tried to Open as Administrator but get the same prompt. After downloading each fix that I find on the internet, I click on the repair exe files and get, "ShellExecuteEx failed, code 2. The system cannot find the file specified." I have tried to open Regedit.exe but get the same result. can anyone help in any way...

Reboot into safe mode, at the login screen press ctrl+alt+delete twice, should give you the classic usn/pass window.
Put in administrator for the username and try logging in without a pass.
If it works you just got in what is basically windows' super user account.
Try doing your installs and whatnot that way.
If you can't get in, well, I would just reformat.
Back up all your important files to an external hard drive if you can.
If not, remove your hard drive, slave it to another computer, back up your files that way.
Wipe the drive and start over, it's always better and easier than trying to remove deep-set malware and repair windows.

That seems to have worked so far, running a scan with hitman pro and malwarebytes along with avast pro while in safe mode, ill reboot once they are done and rescan in normal mode, if nothing else, ill have to reform.. Hitmanpro has returned nothing from safe mode, still waiting on the other two however

Alright so the other two finished running, no issues while in safe mode, i switched back to normal mode however im still unable to run both programs, keeps saying that they cant be found.. hitman however runs on startup, it found nothing, sadly..

So, the root of my problem seems to not be just any program that i cant run, only programs that require admin rights, sadly i was not able to get the super admin account to work, or i would have made another account with admin rights to see if the first one is just becoming corrupt

An antivirus that does not find virus, how come I'm not even surprised...

I don't know if you really can't use regedit or if it's a leftover from canary67's post copy-paste, but anyway, try this to edit your registry.

For your malware problem, and if you got regedit to work, this thread could be an interesting read, though it mostly sums up as: look at all your run/runonce registry keys and delete anything suspicious (both the registry entry and the referenced file).

All folders in c:\users (win 7/vista) or c:\documents and settings (win xp) represent one account (though there are a few more accounts on your computer). See if your hacker has created himself an account, which will most likely have admin privileges. Then try items 6-10 from here to remove the hacker's account password, then log as him and create/restore your admin account.

Finally is your current admin account windows's built-in admin account, or one you created?
If it's one you created, try item 5 from previous link.

there is one folder/user that i dont know of, but it was created over a year ago.. called Updatususer ~shrug~ it doesnt show up on log in screen, has no files/rights that i can tell. The account having the issue is any admin acount i had previously, besides the built in admin, which is now active. the issue has downsized itself considerably from not being able to run any programs to now just not being able to use programs that require admin rights, the only account that can use them is the built in admin, my other two admin accounts cannot. also, the built in admin cannot access any of the controlpanel< users functions of changing account types, or access the UAC Basically anything with the blue and yellow shield in control panel for the built in admin, anything with the shield for my made admins

Ive checked through the registery for out of place things, and nothing really stood out nothing was in my run or run once folders, so ~shrug~

(PS had to butcher your post a bit.. couldnt post urls)

As the built-in admin, try start menu->run, and type lusrmgr.msc here. Can you run it?
if yes: I guess you know what to do by now...
if no: what error message do you get? Also try the others lusmgr.msc (I have 8 ones scattered under my windows\* directory).

If you didn't see anything odd in the run / runonce keys maybe the infection is cleared after all, check the scheduled tasks when you have the rights though.

FYI: File and folder timestamps are fakable. I hope that extra u in Updatususer is a posting typo, otherwise it is script-kiddie-ish=suspicious.

Ran lusrmgr however it gives a error stating win 7 premium is unable to use this snapin, use the user control panel to manage accounts

im still unable to run programs by my admins that have the shield (admin protection) except by admin built in account..

the extra U was not a typo, it is as posted -> UpdatusUser <-

Actually, what happens when you try to access control panel->user account settings as the BI admin? (if you get an error message, give me enough to google for it this time)

If the UAC is blocking you, you can try this

Can you run sfc /scannow as the BI admin?

As for UpdatusUser, google shows it is nvidia optimus related. Nothing to see here.

As BI admin try creating one more admin by entering in cmd:
Code:
net user USERNAME PASSWORD /add
net localgroup administrators USERNAME /add
Then log on as USERNAME and see if it is allowed to manage accounts.

Note: just found the the runas command within cmd, which might have been useful earlier.

When trying to access the UAC via BI admin, it flashes for a moment, barely even a glimpse of the window or process, and then closes/shuts down the process before anything can be done

trying to access on my made admins results in the error of "windows cannot find this, make sure you typed it right and try again"

Could not run sfc as made admins, could however as BI admin, did this, nothing was corrupt per scan results

very well, that would be about the time that i updated the nvidia stuff, last modified a few months back

Looks like to me some process is actively closing the window for you. Could you post a screenshot of your taskmanager showing the columns image name, image path name, and command line? (the last 2 are the most important ones)

What happens if you run c:\windows\system32\UserAccountControlSettings.exe as BI admin? As made admin?
(btw there should be a ~83kb UserAccountControlSettings.dll, check it's there)
If it instant closes, try renaming the .exe.

In regedit check the permissions for HKEY_CLASSES_ROOT\AppID\{EA2C6B24-C590-457B-BAC8-4A0F9B13B5B8}. Mine are:
System, Administrators and Users: allow read
Trusted installer: allow full control
nothing else


This probably won't change much, but open explorer (not internet explorer), go to the "%temp%" folder (just type it in the address bar), and delete everything here. Viruses like to hide themselves here. If you get any message saying a file can't be deleted because it's in use, start investigating.

Instant close, attempt to rename brought up a popup stating require permission from trusted installer to do this ( screenshot 3)

last but not least screenshot 5

the file in screenshot 5 called " FXSAPIDebugLogFile " could not be deleted as it was in use by windows explorer i typed in the search bar %temp% and thats the folder it gave me, if its not the right folder, ill try harder next time Razz

Shots 1 & 2: Your system looks free of simple malwares, unfortunately. Still give shot at Sophos anti-rootkit.
I've never used that sophos' tool, but if that doesn't work the last idea I have before suggesting a repair reinstall is running combofix which require you to disable all resident protections/AVs (you have avast, but don't forget you have microsoft defender too). I'm suggesting to run it because it fixes some stuff on top of removing malwares, but you'll see a lot of warning like "you should run combofix (CF) without the supervision of trainer personnel" on internet, well I'm NOT what they call trainer personnel, as I don't know what CF exactly does. Then again, if you're about to reinstall windows, it's not a big deal if CF puts your OS upside down.
One more thing: combofix will disable your lan/internet access, do not attempt to restore it, heck don't touch your PC while it scans.

UserAccountControlSettings.exe: make a copy of the exe, and rename that copy.

shot 4: I meant right-click on {EA2C6B24-C590-457B- BAC8-4A0F9B13B5B8} and select "Permissions..." in the drop-down menu.

shot 5: you're in the right folder. The .tmp file could have been a virus at some point, but Microsoft also loves to rename its temporary exe that way.
Hiding a virus in a .log file would have been odd, but not impossible. Well it turns out %temp%\FXSAPIDebugLogFile.log is generated by Windows Fax and Scan service -> no problem.

BTW: alt+print screen = screenshot of only the active window.

Made a copy and renamed to its short hand of UACS, Same as if opening the first, blinks for a moment then shuts down

Duh... i knew that... Mad (not really Razz) anyhow, this is how myne is:

System - Read
Administrators (Valued customer[computer name]\Administrators) - Read
Users (ValuedCustomer\Users) - Read
TrustedInstaller - Full control / Read

Ive attempted to change admin to full controll/read and revoked trusted installers to just read.. because i dunno what that is/where it came from but i got an error message stating "Unable to save permission changes on (lists the long arse string Razz) access denied"

Alright, thats a good thing then, the log was scarce of anything, but again, that could be made to look as such.. but still, its from fax/scan (then again.. i dont use windows fax or scan... so..)

Learn somethin new every day Razz


Edit:: As a side note I keep getting these random named files poping up in my download directory when ever im on my BI admin account to install/remove things, is this normal?

Trusted installer is a bullt-in account that is created when installing windows and that is used for installing core components & updates and preventing users/admins from doing stupid things. Admins can of course overwrite Trusted installer's rights when they really want it, but that is not recommended.
If you couldn't change the rights of the previously mentioned registry key, that's because you would need to change the rights for parent keys first, but it's better to let those permissions as is since they are the same as on a sane machine: mine.

No, it's abnormal. My download directory is empty (save for a desktop.ini file). Try to open one with notepad and if you see "This program cannot be run in DOS mode" near the beginning, well it's a disguised exe/dll. Even if this string is absent, if the 2 very first character are "MZ" there are chances it is a program.
Randomly named files are normally stored in %temp%, unless those are temporary download files. I saw you had bitcomet running, but I dunno if it's it.

Just in case see if there is a baddie in:
C:\users\Administrator\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Let me know if sophos finds something.
