Only two things that I can see in Speccy (apart from updates that have failed to install) is that you only have the one stick of RAM which means that it is only running in single channel mode which is half of the speed that it is capable of, this also results in most of your RAM being used which again slows down the performance.
Being a HP you will have a certain amount of bloatware on the SSD so we can check that at some point but to begin with can I suggest that you get rid of Avira as you do not need it, see explanation below.

Windows 8, 8.1 and 10 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.
Having more than one AV installed on your computer is bad, it will slow down the computer, cause internet connection problems and leave you with no AV protection at all if they cancel each other out as they fight for resources.
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.
