Done
@Bare Foot, i have installed Malwarebytes but every time i start it the uninstall windows for BitDefender (my antivirus) appears and after i press cancel for several times a error apperars (from Malwarebytes) which says "an error has occured. please report this error code to our....... MBAM_ERROR_LOAD_DATABASE (0,5)". I presume this is not the usual behavior for this software

.
@Brink. I have searched all those and i have deleted all of them (except for internet explorer), there were 5 or 6, but nothing have changed except that now i dont have any more in folder options the option "Always show the menu bar"... i have changed from Organize>layout but doesnt work.
