Couple of things of note in Speccy that will affect overall performance and a couple that will affect internet performance as well.
RAM
4.00GB Single-Channel Unknown
Your RAM is only working at 50% of what it is capable of, run the Crucial system scanner tool here to see if you can add another stick which will give you dual channel.
Your HDD is the slowest SATA type drive that there is and unfortunately there is nothing that you can other than upgrade the drive to a 7200rpm or an SSD.
Antivirus
Windows Defender
Antivirus: Disabled
Virus Signature Database: Up to date
Kaspersky

You have a third party AV when you really don`t need it, get rid of Zone Alarm as well, see the below;
Windows 8, 8.1, 10 and 11 come with an improved Windows Defender, it offers the same real-time anti-virus/anti-malware protection as Microsoft Security Essentials. Windows Defender also shares the same malware signature definitions as Microsoft Security Essentials, and Forefront Endpoint Protection. Technically, Microsoft Security Essentials has not been renamed Windows Defender, or combined with it in Windows 8, 8.1 and 10.
If any AV product that you have is a paid for version you should always make sure that you have a copy of the product key kept somewhere safe just in case you ever wish to reinstall it.
Once any other AV has been correctly uninstalled, check to see if Windows Defender has auto enabled and allow it to update and carry out a full scan of your computer.

Once done, restart, test by using the computer as you normally, post back with an update when you are ready.
