Hi, good advice from the previous posters, you do need to read the instructions for the nirsoft utils, maybe give us a screen shot of your current right click context menu.
This site is very comprehensive (and trustworthy) The Nirsoft programs (you need two utils) are towards the bottom and instructions are included. (applies to win 10 as well).
You appear to have Avast, Malwarebytes (I hope that is the free version) and elements of McAfee on your machine. Any AV apart from windows defender is a problem for a home users computer. Two AV's will and do conflict with each other. My advice to improve your security and performance, use Avast's uninstaller and McAfee's uninstaller and be rid of them, use only the free version of malwarebytes if you must, I don't recommend it, and use what most of us do now, Widows defender.
