idontlikeviruses

sorry this is in the wrong section

ok so i've read through like a bazilliongillion different guides on how to remove antimalware doctor, the stupid fake virus thing. i don't want to do it manually, i'll screw something up. i downloaded malwarebytes or whatever, but it won't start up, i'm assuming because of the antimalware doctor i read somewhere else to change the file name and try, but i have no idea how to do that. can someone help me please and sorry if this has been asked/posted before
