Been using anti malwarebytes last years as complement for anti virus and working great so far.
Another that isnt at list and just downloade d 2 days ago is Update checker that checks all programs you have installed if they are up to date, and if they arent it tells and gives you download link, pretty great it appears, and barely uses any memory.
