Speccy doesn't look too bad but there are a couple of pointers for you;
You have a 64-bit OS but only 4GB of Ram, 8GB is considered the sweet spot for a 64-bit OS + adding more Ram is still the most cost effective all round improvement that you can make, consider swapping in 2 X 4GB sticks of Ram at some point, see my canned text below;
Use the Crucial system scanner tool here to find the best recommended Ram
and SSD for your system, no need to purchase from there, write down the details, let us know what is suggested and we can take a look for you.
You have the following software and scheduled updates on your computer that may not only slow it down but also make it unstable, I will let you know which;
Running: Norton Online Backup - will slow things down, fine if you use it but get rid if you don't.
Stopped: McAfee Application Installer Cleanup (0055311439400629) - these two may be shown to not be running but if either does it will conflict with Kaspersky, slow down the computer + there is the possibility that Kaspersky could be cancelled out leaving you with no protection.
Stopped: McAfee Security Scan Component Host Service - as above.
The following scheduled updates are totally unnecessary, they will bog down your computer, you should decide when you search for and install updates for any software other than the OS and your AV;

Going offline shortly myself as its late here in the UK, don't want to weigh you down with things to do all at once so will leave the information for tidying up your HDD until tomorrow at some point.
