first of all, I would like to apologize if i make any mistakes in my writing since english is not my native language. ok, now I would like to ask for help because since yesterday a strange popup window has started to appear as soon as i enter my desktop from the metro icon(I am running windows 8 pro) and it is just a blank message titled "explorer.exe" . other than this, my antivirus(avast, the free version) warns me about 2 viruses, one called nt32 and another called load32 . these programs didn't do much, they simply removed the ownership of some programs from me while i was running them(thus shutting them down without saving) and also removed the language bar from the bottom of my desktop, but i managed to solve these problems by myself. while browsing through the internet i came to this forum twice, finding people with problem similar to mine, but in neither of them i found a solution, since the people that helped them requested logs and scans from various programs. another solution that i found was to delete a strin from the registry called "load" which would be situated in HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows . i tried to delete it multiple times, even after taking ownership of it but it always ended up displaying an error saying that it couldn't delete all the values of the string. last of all i tried deleting the folder in which the program was situated( c:/programdata/ntkernel ) after a diagnostic startup and i succeded, but after i rebooted the computer the folder was still there and the program inside of it was gone, but the process still running even though i couldn't see it and the folder was undeletable by any means. can someone help me, please. thanks in advance for your help!
