Additional Tips: How Do I Make Windows More Secure?

Well, keeping your computer secure will help users to avoid potential malware attacks and direct hijacking attempts to steal personal data. At WeTheGeek, we recommend our readers implement the following tips to secure your Windows PC:

1.Use A Firewall

Windows already comes pre-installed with a dedicated Firewall to get protection against cyber attackers and prevent malicious programs from accessing your PC or network. Alternatively, you can take help from third-party Windows Firewall Programs to get an additional shield!

2.Keep All Windows Programs Up-To-Date

Ensure that you keep your device and all the installed software completely up-to-date. You should consider turning on automatic updates in Windows and for non-Microsoft software as well. For this, you can take the help of a dedicated Software Updater Tool to safely download the latest upgrades of the Windows tools.

3.Run A Reliable Antivirus Software

Well, to be honest, running Windows Defender (the built-in security feature) is certainly not enough to fight against sophisticated viruses and malicious content that are surfacing these days. You should conduct thorough research and shield your computer with additional Internet Security Software like Systweak Antivirus, AVG Ultimate, Norton Security Standard, Kaspersky Total Security, Bitdefender Internet Security, and so on.

4.Regularly Change Your Passwords & Keep It Unique

It is important to change your passwords frequently – to limit breaches to multiple accounts, prevent access gained by keystroke loggers, and reduce the risk of constant access. You can follow our complete guide on How To Create Strong Passwords & Remember It?

5.Use Safe Browsers

We recommend users follow comprehensive digital hygiene and avoid visiting websites that offer illicit content. These sites are specifically designed to install malware & viruses on the user’s device. You can go through our list of Most Secure Web Browsers for Windows and enjoy the best protection while surfing on the Internet.

Well, before we wrap up today’s article, let’s keep our hopes high that Microsoft will soon release an effective patch to block unauthorized access caused due to the zero-day flaw – CVE-2021-34484.
