Guessing you have windows, try running msconfig.exe. Go to run, type in msconfig.exe. See if you can find the programs listed under the START UP tab and uncheck the box next to them, then restart. This wont uninstall but should disable it from starting with windows. You can always go back and check the boxes if something isnt right after doing it. To find the files, try.FIND then FILES AND FOLDERS and type in offeroptimizer see if it can find it. Some spyware cant be uninstalled.
