I used ATF cleaner, then i installed the mbam exe, and clicked on it to put MBAM on my computer. but MBAM won't work. it won't open up at all. I click on the desktop icon and nothing happens. I try to go into program files and open it up there, and I still can't open it at all. Why doesn't MBAM work?

You need to change mbam.exe to something else like helpme.exe. That may get it going.

do you mean just rename the exe file?

Yup!

As suggested above, i had the same problem and renamed the .exe file and MBA finally opened.

Cool, proves it can work.

If the program doesn't work, open or install this is VERY often indication of infection. Did you run a Full Scan? If so, did you tell it to remove items found? You should post the log here for review along with a HJT scan log.
