So I've recently just purchaced the new entry level retina display macbook pro. It was super quick untill a few days ago, I havent downloaded anything new same old stuff. But all of a sudden its dramaticly dropped in proformance (altho still quick) a very noticeable diffrence from before. Is it possible that I may have gotten a virus? Its acting as if I have. Thoughts?


MacBook Pro with Retina display, Mac OS X (10.7.4)

    No viruses nor trojans. Look for some other cause. Start by:

     

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.

    Viruses & worms, none. Trojans, that depend on social engineering, yes. For instance, that damned POS called MacKeeper.

     

    Like Kappy indicates, there's some process running there that's messing with the performance by eating up CPU cycles.

    Does your computer run slow after a restart? Like others have said, check your Activity Monitor. Also, aside from being sluggish, what other symptoms do you experience, if any? Often a restart can cure many ills.

    And a Safe Boot restart can sometimes be even more helpful in some cases. Doesn't hurt to try, as no harm will come if it doesn't help. Just be patient. After it finishes booting in Safe Mode, you can restart nornally and see if things have improved.

    Can you quantify this in any way? You definitely don't have a virus. Have you installed some other type of software?
