Before we get into the prevention details, let's start with a fundamental question: What is a computer virus?

A Computer virus is a program, script, or code designed to steal personal information, cause damage, modify data, send Emails, display messages, or some combination of these actions.

Viruses need a host to produce and spread, such as a file/document, USB drive, apps, software, or a malicious link. It can also replicate themselves into or over data files, programs, or anything writable on your computer.

8 keyways to prevent your PC from viruses content

Here are the 8 keyways that you can protect your computer from viruses:

1. Research first, Install later.

Please spend a few minutes to do some research on the apps/software and reading the user reviews before downloading it. A reliable apps/software should have a sizable number of studies; otherwise will likely have very few and frequently all 5-star rating.

Never downloading a free app, software, and other content without checking the reliability of the sites or verifying their legitimacy, it is more likely to contain viruses that can infect your computer.

2. Install trusted apps/software.

Always download apps/software from the original supplier or a trusted third-party website, such as Apps Store and

As we know, there are many Freeware sites nowadays for people to download free applications; however, we do not know what will happen until we installed it. Therefore, we need to be more cautious when choosing a software download site!

3. Keep everything updated.

New viruses are being created every day; hence, you should make sure all the software, apps, antivirus, and operating system are up to date to protect your computer from the latest threats.

It is essential to keep your Operating System software such as Windows and antivirus software updated. It helps to eliminate "bugs" that hackers could exploit and with a high chance of evading a virus's grasp.

4. Stay alert to untrusted sites/links.

Never visiting an unfamiliar website. A trusted site is secure by SSL (Secure Socket Layer) certificate. In URL, it will start with "https:// "such as a lock icon will display on the URL bar.

Think twice before you open an attachment from emails where you don't know the sender or from a trustful of friend or colleague that you know. Generic scam subject line's keywords such as "Payment Status', 'Are you available?', "Purchase" accompanied by a link is most probably malicious so don't click on them.




It's important!

5. Do not plug-in random USB flash drive.

Whether you got the USB flash drive from someone you trust, company colleagues, or family members, you should always scan the flash drive in before transferring data. To keep things simple, you can enable the auto-scan from your antivirus programs for any external media to get plugged in and detected by the computer.

Unlike virus link (requires user click on it), the flash drive is depending on users plugging an infected USB into a machine or flash drive plugging into an infected computer. Thence, please keep your USB carefully and don't give anyone a chance to harm your computer.

6. Maintain a monthly clean up.

You can include the computer housekeeping in your monthly to-do-list to remove the unnecessary files or software in your computer, the less software you have installed, the fewer possibility of potential virus attack.

Disabling and modifying unnecessary default features of the apps/software also eliminates several opportunities for attack.

7. Keep Your Password secure and long.

Avoid using common passwords such as ABC123, Password123, or 123456 and do not use birthday, Identity Card number, phone numbers, or pet name as password. The best passwords that are at least 8 characters in length and include a mix of numbers, letters that are both upper and lower case and a special symbol. A strong and complex password is difficult for hackers to find.

Do not use the same password combination across multiple sites. If a hacker has discovered one site, it takes only seconds to hack all your account.

8. Set antivirus protection.

There is a classic and free antimalware software that comes with Windows called Windows Defender, and it makes you aware if there are any unauthorized efforts to use your system. It is FREE, so please remember always turn on your Windows Defender and set it to update automatically through Windows Update.

If you have a budget, it's recommended to choose a paid antivirus software that provided more advanced features. You should give your computer a thorough scan at least twice a month. Your computer will be running slow while your antivirus software is scanning, you can set a day just to run the virus scanning and make sure do not shut off automatically or go into hibernation mode.
