Mac OSX very slow


We have a fairly-new iMac that has an i5 processor and 4GB DDR3.  Not sure why, but it's so slow, it's ridiculous.  You'll literally click on a program and count the seconds for it to come on.

Is this an issue with iMac?  Is there anything that can be done?  I tried disabling startup items but that didn't help too much.

Actually I found a rogue copy of Kaspersky AV, removed it, and it seems to be working a bit better.  Is there a way to see a list of software / services installed in Mac?

Delete from Application any antivirus or improvement software (like MacKeeper). There all are junks. MacOS don't need anything of that kind!

From Disk Utility run repair permissions and check disk

If all above won't work you need to replace the HDD. Clasic (mechanical) HDD is the slowest component from a system of this days and is the single one which can slow the system without having errors to occur!

Looking at the Activity Monitor is a great suggestion and I 2nd it. Also double check the Photos app to see if you're uploading thousands of pictures to the cloud... that is a common reason for slowness of Macs recently.
open Photos > Go to Preferences > iCloud and if iCloud Photo Library is checked and it says you're uploading, then click "Pause for one day" and see what the speed is like then...
