New member here. I see that this problem has already been addressed in another post in July, and the fix steps offered, but I read that that fix is specific to that machine only. So I have the same problem, also Windows 7. That is, Emsisoft detected that \Windows\System32\sdclt.exe is attempting to modify and autorun entry. I attempted to quarantine, and Emsisoft popup replies that "these files are essential for Windows to work, you can't delete or quarantine them now." I am instructed to ask the Emsisoft Forum for help in its removal. I am not tech-savvy. Please help. thanks.
