Tips to be safe online
- It is preferable to avoid websites with unique domain extensions other than .com, .org, .net, and.edu. Because most infected websites have extremely distinct TLDs, always verify the last part of a domain to ensure that you are visiting a safe site, unless the site has been reputable ever since.
- Never acquire software or programs from unknown sources, as this is one of the most common ways for browser hijacker and other types of malware to attack your computer. Only download from reputable and legitimate websites. To be safe, stay away from torrent downloads and cracked software download sites, as there will always be malware in the files.
- Using a firewall is one of the most foolproof ways to be safe online. It serves as a first line of defense against dangerous websites, shielding visitors from potential risks. It protects the user’s network and device from intruders. A firewall will safeguard a user from the threats hiding on the vast internet in today’s age.
- It is essential to keep anti-virus software up to date on a computer since hundreds of new malware threats are released every day that target the machine’s vulnerabilities in order to infect it. Anti-virus updates include the most recent files required to counter new threats and safeguard your machine.
- Only visit websites that has a secured connection. A site with HTTP connection does not encrypt the data it receives and therefore is not considered secure. Entering personal information such as email addresses, phone numbers, and passwords on a website with an HTTP connection is risky since it could be compromised and your information stolen. Websites with HTTPS connections, on the other hand, are secure since data is encrypted and attackers are unlikely to gain access to information exchanged within the site.
