Hi A friend of mine gave his mac book to his daughters and they ended up downloading Mac Keeper (the one with the robot). So our IT spent the morning cleaning up his computer. I was right beside listening while doing my stuff. Basically, Mac Keeper was asking to install certain FLASH PLUGIN, even at the Google home page that does not requires flash. It seemed that it needed flash installed to infiltrate the computer. Even with no browser open every other software was running slow. I believe we deleted flash and I do not know what else but after a good hour the computer was just fine.
