We tend to visit a lot of websites throughout the week. However, it's important to keep an eye on what kind of websites you visit or even links you click on: you can compromise your computer when visiting unprotected websites or click on malicious links. Here are some tips you can follow to more securely browse online:
Always double-check the links you click on: make sure that the spelling is correct or that if it's a linked URL, that the URL doesn't take you to something that you don't recognize. The link you click on could lead to a phishing scam or a malicious website that looks to extract personal information from you or download viruses onto your computer.
Also, websites do have security certificates to provide legitimacy to the site you're visiting. But even legitimate websites can be compromised and have things such as malware embedded within them without the website owner knowing. The best way to combat that is to make sure your browser is updated to the latest version when possible.
