My MacBook is slow starting up and slow when I am on internet going to sites.  I read somewhere that there is a adobe flash that is actually some sort of virus?  I beleive I had the pop up and hit install.  How do I fix if this is the problem?

    Adobe Flash is not a virus but Flash content is very resource-hungry. Flash developers don't know or care about your hardware or bandwidth, both of which have limitations. Buying a new computer simply so that you can look at Flash-based advertisements makes little sense to me. Just avoid sites that use Flash.


    There are no viruses for Mac OS X. Keep it updated with software from Apple using Software Update. Without a more specific description of your hardware, the amount of memory you have installed, what third party system modifications you may have made, and what version of Mac OS X you are using, it is difficult to provide more specific guidance than that.


    Read the following to determine if something may apply to your concern:


    Do not download or install any product claiming to magically "clean up" or "speed up" or "optimize" your Mac. Without exception, they will do the opposite. If you already did, you found the problem. Fix it.


    If you're experiencing general slowdowns or "freezes" unrelated to Internet activity, the problem may be related to your computer or the software you installed and is something you may be able to fix, or at least improve. Aside from hardware failures and software that you install, including OS upgrades, there is no reason that your computer should not work precisely the same as it did when it was new.
