I brought our iMac (Mountain Lion 10.8.2 3.06 GHz Intel Core Duo2, 4GB 1067 MHz RAM ) into the genius bar a couple of weeks ago for a "tune up" before the warranty expired and the tech had it running great. He also recommended that I upgrade the OS to Mountain Lion and since then my computer has been sluggish to say the least. Internet connectivity is at a snail's pace and often I need to restart just to connect to a website. My wife thinks she may have invited a virus from Facebook and I've installed Kaspersky but everything looks clean. Any ideas?
