pop ups in 64bit browser

I recently found a file in the temp folder under my user profile called IJJ.exe.

 

Could it be the source of the popups? Anyone know if this file and what it is? My computer was also infected with a Trojan ibebua.exe, backdoortidserv!3. There was another file similarly named IJK.exe.

 

Is my machine still likely to be infected with the virus, or is it just the presence of this file that causes the popups? I have deleted the file once I discovered that it was actively running as a process in the background, but can't help but wonder if it will come back, or has reappeared somewhere under a different name.
