IMac performing very slow!

Question

HI all,
I am running an imac with Maverics. I have 4GB of memory with a 2.7 Ghz processor. I have a 3 TB external drive and using Time machine with daily backups. The problem is, for the past few months, the performance of just about everything runs super slow. here are some examples:
1. Upon opening any application or program, I get the Spinning ball
2. I get programs shutting down unexpected all the time. 
3. My mac is set to auto shut down at midnight. Ill wake up in the morning with error m,essages saying certain programs wouldnt let it shut down.
4. I have checked my Internet speed and am getting great upload and download speeds form the server, yet the safari webpages take forever to open.
5. OPening any files takes forever. Almost as if when its trying to read the file to pen it, it gets stuck.
6. Response from any data entry is slow. ie. as I type in a chat box or email, the letters and words are still populating in the box or email but Im done typing.
There are some others happening biut those are the big ones.  Its annoying and very frustrating.  My brother has his imac, same year, and it runs so fast and smooth and I have been trying to get to that point but cannot. Should I bring into a mac store and let them run their program on it and see if my imac is infected or at the very least, they can find the issue?
Thanks for the help.
Regards
Lou
