MACBook Pro - Extremely Slow with Freezes

Question

Hi,
I have this macbook pro model
  Model Name:          MacBook Pro
  Model Identifier:          MacBookPro9,2
  Processor Name:          Intel Core i5
  Processor Speed:          2.5 GHz
  Number of Processors:          1
  Total Number of Cores:          2
  L2 Cache (per Core):          256 KB
  L3 Cache:          3 MB
  Memory:          4 GB
And with 385 GB out of 499 GB of free memory.
I have practically nothing on it, no huge files & not more than the basic apps., nothing !
However, I have a very slow response. Word sometimes takes a minute to open when I only have just Chrome running in the background.
It gets worse when many apps are running together, but even then its only basic apps nothing major. Safari would normaly take not less than 20 seconds to open. I have just dropbox thaat run automatically after start up but nothign else. Still most of the time I am faced with the slow response. The spinning beack ball is always on to, which makes me force quit alot of time.
My battery is working quite well
Thanks for the feedback !

If you choose to use garbage such as "Intego VirusBarrier" you are going to need more memory, a lot more. I suggest you uninstall it according to its instructions, and evaluate your Mac's performance without burdening it with completely useless junk. As long as Intego remains active, your Mac will have few resources remaining to do anything else.
Using Intego's "Virus Barrier" and "Net Barrier" products on a brand new Mac containing nothing but one minimally configured user account resulted in performance degradation so severe that it became nearly unusable. No knowledgeable Mac user would consider using it even remotely tolerable.
Intego should only be uninstalled using the uninstaller included with it. Don't use anything else. A successful uninstallation will result in the following:
After that, restart your Mac. Other Intego components will remain but they will be inert and will not affect your Mac's operation.
