hello and welcome to this great forum friend
I hope that you can change "nope" by programs like
ccleaner , backup the system and important documents ... consider good use of
Malwarebytes as on-demand scanner as well as using another browser, this course if you want to become more protected while you surf through the internet
important extensions:
WOT(web of trust) for check all the links
and block malicious ones, and
HTTPSeverywhere (HTTPS Everywhere is a Firefox, Chrome, and Opera extension that encrypts your communications with many major websites, making your browsing more secure).
...and you should consider using
sandboxie to browse safely.
cheers
