2. Spyware

Spywares usually covertly install into the computer with other programs or extensions. When not noticed early enough, it can cause serious data breaches that can be detrimental to a business or person.

In a phishing attempt, the cybercriminal impersonates a business entity or trustworthy person to access sensitive financial and personal information.

It takes advantage of human error and carelessness to lure them into disclosing confidential data.

How To Secure Your Windows PC In 2021

1. Use A VPN

A common concern for most PC and internet users is the possibility of having a government agency, online hacker, or even the ISP checking their online activity. The best way to avoid this is by use of a Virtual Private Network (VPN). Using a VPN locks out any potential online spies by making data to and from your computer unreadable. All data is transferred through a secured channel, making it only accessible to the sender and recipient.

2. Keep The OS Updated

Updating your Windows OS is one of the best ways to protect it from security breaches. Always be on the lookout for new updates and install them as soon as they are available. These new versions come with security patches for vulnerabilities in the previous version. You can also set the update to install automatically by changing the settings from the control panel.

3. Update Your Software

Hackers consistently use popular software programs like Adobe Flash, Java, Adobe Shockwave, and Adobe Acrobat Reader to access computers, especially if you are running older versions of these programs. It is important to ensure that they are always updated with the latest security patches, making it harder for hackers to exploit them to access your PC.

4. Use An Antivirus Program

An antivirus program is the best solution for protecting your PC from malware. When looking for an antivirus program for your computer, ensure you only invest in one from a reputable company. While there are free versions, a premium program comes with better tools to fight even the rarest of malware.

5. Avoid Downloading

Make sure that you are not downloading any files from untrusted websites. Look at the URL of the site you are visiting and ensure that they have enabled HTTPS for secured file transfer and safe browsing. You may also check the Domain Authority (DA) of the site you are surfing (Higher the DA, safer the site) and download only the defended files.
