I downloaded an .exe file, and ran it, it popped up and disappeared very quickly
seemed strange so I scanned it with MSE, and nothing was found, then seconds later I receive a 'action centre' message saying MSE has been disabled, and when I click on the message it says MSE can't be started, when I try to open MSE independently it says " Windows cannot access the specified device, path, or file. you may not have the appropriate permissions to access the item."(even ran as administrator). I don't know if the action of scanning stop MSE or if it would have happened anyway, but windows defender has been disabled with all the same results, so i assume it would have anyway.
I have tried reinstalling MSE, but it says its already installed, when trying to uninstall current MSE its says "you do not have sufficient access to uninstall MSE. please contact your system administrator."
I have malwarebytes anti-malware installed, and have done a quick scan with nothing been found, have used Microsoft windows malicious software removal tool quick scan, with no results
I'm currently doing a full scan with malwarebytes but am not hopeful that it will find anything
I have seen other threads saying ending the process tree of rundll32.exe allows temporary access to MSE (before a reboot), but it hasnt worked for me
Cheers in advance,
