|>> || after that you can start installing drivers |
if OP pic is your laptop, then go on hp.com and search your model. then look for the drivers and download and install them.
how do you know if you have all drivers? run device manager and see if you have any yellow exclamation marks. Device manager is accessed by start, right-click my computer, properties, hardware tab, device manager.
get firefox 52.9 ESR. that's the last version. they won't update since september
you definitely want to install ublock origin on it to block ads (primary vector of malware)
you'll need an archiver (7-zip or winrar), a pdf reader (your call, just don't get the one from adobe), and a media player (mpc-hc is great, vlc is also good). CD burner imgburn or infrarecorder. image browser is also your call (xnview, irfanview, etc)
security: disable plugins you don't use in firefox (windows media for example). minimize usage of flash if you can. if you don't need, don't even use it. disable file and printer sharing in your network protocols if you're not using them (aka you're not on a network with other computers). (control panel, classic view, network connections, right-click your adapter, properties, uncheck protocols not used). you can also disable netbios over tcp/ip in advanced tcp/ip settings, under WINS. if you want to disable dcom (and close port 135), use dcombobulator from steve gibson.
I presume you have enough good sense to not run executables from untrusted sources, but if you don't, then get antivirus.
or upload the file to virustotal.com before running it
(as practice, upload the files you downloaded earlier to check they're safe)
now to be "in tune" with what goes on in your system, you should look at task manager regularly (right-click taskbar, task manager). often look at processes and performance tabs. in the processes tab, go to the view and pick more columns to view (I recommend cpu time, i/o read bytes, and i/o write bytes). with all the columns visible, you can monitor CPU, RAM, and disk usage.
second, look at event viewer regularly. it's in your administrative tools. (control panels, classic view)
last, you may want two additional tools: tcpview (to monitor your internet connections) and process explorer (like task manager, but much more powerful)
there's tons of other fun tools to learn about you system like hwinfo32, cpu-z, gpu-z, hwmonitor, and many more.
happy learning, and stay safe.
