Check How to protect PC from hackers who can track you
Cybersecurity is super important. We spend a significant part of our lives online and on computing devices. Whether it’s a laptop, a smartphone, or your desktop at work, you have valuable information that suspicious people would like to have. Wouldn’t it be nice if you knew how to protect your computer from hackers and all the other dangers of the digital world? The good news is that it’s not difficult to learn some basic tips and tricks that will greatly improve your online security. A hacker is a techie who can solve a problem in a non-standard way using their computer, network, or other technical skills.
Today, the term can also refer to criminals who use their skills to steal personal information or gain unauthorized access to systems. By the way, in addition to their technical “voodoo,” hackers can also use psychological manipulation to trick people into revealing data or granting access to their devices. This is known as people hacking or social engineering. There are two ways hackers can try to get your personal information. One way is to try to obtain information directly from an Internet-connected device by installing spyware, which sends information from your device to other people without your knowledge or consent.
How to protect PC from hackers who can track you
use a firewall
Windows and macOS have built-in firewalls: software designed to create a barrier between your information and the outside world. Firewalls prevent unauthorized access to your company network and alert you to any intrusion attempts.
Make sure the firewall is enabled before connecting. You can also buy a hardware firewall from companies like Cisco, Sophos, or Fortinet, depending on your broadband router, which also has a built-in firewall that protects your network. If you have a larger company, you can purchase an additional enterprise network firewall.
Install antivirus software
Computer viruses and malware are everywhere. Antivirus programs like Bitdefender, Panda Free Antivirus, Malwarebytes, and Avast protect your computer from unauthorized code or software that can threaten your operating system. Viruses can have easy-to-detect effects—for example, they can slow down your computer or delete key files—or they can be less noticeable.
Antivirus software plays an important role in protecting your system by detecting threats in real time to ensure your data is safe. Some advanced antivirus programs provide automatic updates, further protecting your machine from new viruses emerging every day. After installing an antivirus program, don’t forget to use it. Run or schedule regular virus scans to keep your computer virus free.
Install an anti-spyware package
Spyware is a special type of software that secretly monitors and collects personal or organizational information. It is designed to be difficult to detect and remove, and tends to display unwanted advertisements or search results intended to direct you to certain (often malicious) websites.
Some spyware logs every keystroke to gain access to passwords and other financial information. Antispyware focuses exclusively on this threat, but it is often included in major antivirus packages such as those from Webroot, McAfee, and Norton. Antispyware packages provide real-time protection by scanning all incoming information and blocking threats.
Keep your operating system, applications and browser up to date
Always install new updates to your operating systems. Most updates include security fixes that prevent hackers from accessing and exploiting your data. The same happens with the applications. Today’s web browsers are becoming more sophisticated, especially in terms of privacy and security. Be sure to check your browser’s security settings as well as install any new updates. For example, you can use your browser to prevent websites from tracking your movements, which increases your online privacy. Or use one of these private web browsers.
Beware of emails from unknown third parties and never click on links or open attached files that come with them. Inbox spam filters have gotten pretty good at detecting the most notorious spam. But more sophisticated phishing emails that mimic your friends, associates, and trusted businesses (like your bank) have become common, so be on the lookout for anything that looks or sounds suspicious.
Turn it off
Many businesses, especially those that operate a web server, are “all systems up” all the time. However, if you’re not running a complex Internet-based business, turn off your machine at night or for long periods when you’re not working. Being always on makes your computer a more visible and available target for hackers; shutting down breaks the connection a hacker may have established with your network and interrupts any potential mischief.
Protect your network
Routers do not usually come with the highest security settings enabled. When setting up your network, log in to the router and set a password using a secure, encrypted setup. This prevents intruders from infiltrating your network and tampering with its settings.
Even if cybercriminals gain access to your network and files, encryption can prevent them from accessing that information. You can encrypt your Windows or macOS hard drive with BitLocker (Windows) or FileVault (Mac), encrypt any USB flash drive that contains sensitive information, and use a VPN to encrypt web traffic. Only buy from encrypted websites; You can spot them immediately by the “https” in the address bar, accompanied by a closed padlock icon.
Use two-factor authentication
Passwords are the first line of defense against hackers, but a second layer increases protection. Many sites allow you to enable two-factor authentication, which increases security because it requires you to enter a numeric code, which is sent to your phone or email address, in addition to your password when you log in.
