I stupidly downloaded a supposed anti virus program which turned out malicious, producing unwanted popups.
I have tried to remove it by dragging it to trash but it tells me it can't be trashed because the program is still open.
What to do?!!

    Doesn't work!! When I open the Force Quit window the offending program doesn't appear. So it can't be deleted.

    First check System Prefs/Accounts/Login Items and remove any software that you don't want starting at start up. Then restart holding down the shift key (safe boot).

    Also google the term remove <malware> if you know the name of the product you installed.

    Let us know if any of this helps and then we can take it to the next step.

    Reboot your computer in safe boot mode. This is done by holding down the left shift key at startup.

    Keep holding the shift key till you see the text "safe boot".

    Now, remove the app.
