Currently, Windows natively has its own anti-virus Windows Defender, and it works relatively well (Not the best by any means, but well). The majority of the popular providers have free versions of their software to test out, and they also do the job.
So, for anti-virus, I recommend Comodo, Avast, Avira, Bitdefender, Kaspersky or Norton. All of them proven formidable. But if you are worried about the performance of your PC, Windows Defender is your best option, since it doesn’t use that much additional resources, while third party anti-virus solutions might.
With anti-virus, you usually will need to run anti-malware software. Not every single anti-virus has the full package included. Any of the popular software solutions will be solid as well. My recommendations towards ADWCleaner, Malwarebytes, Hitman Pro.
For in browser solution, you could use an Adblocker to protect you from malicious ads, uBlock takes this one for me.
How to download and install? Just google the name of the software and it will direct you to developers website where you can find the instructions that you need!
But when it comes to the internet, no software will protect you 100%. My tip would be to be aware of what you are browsing and downloading. Do not click suspicious links, avoid shady files. Additionally, be careful with emails, a lot of malware is spread through fake/malicious emails. That is the best way of being safe out there. Good luck!
