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?

    First, back up all data and remove the useless Kaspersky product according to the developer's instructions. Reboot and verify that you still have the problem. If you do, proceed as follows.


    Take these steps when you notice the slowdown.


    Step 1


    Launch the Activity Monitor application in any of the following ways:


    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.


    Select the CPU tab of the Activity Monitor window.


    Select All Processes from the menu in the toolbar, if not already selected.


    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.


    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?


    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)


    Step 2


    You must be logged in as an administrator to carry out this step.


    Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.


    Post the 50 or so most recent messages in the log — the text, please, not a screenshot.


    When posting a log extract, be selective. Don't post more than is requested.

    Please do not indiscriminately dump thousands of lines from the log into a message.

    Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

    Those darn anti virus apps seem to cause more problems then they solve.
