How to Check for Viruses on Windows 10

Welcome to this article on how to check for viruses on Windows 10. With the proliferation of malware and viruses on the internet, it’s important to know how to protect your computer system. In this article, we will provide you with a step-by-step guide on how to check for viruses on Windows 10. We will cover everything from scanning your computer to identifying and removing any viruses that may have infected your system.

The Steps to Check for Viruses on Windows 10

Step 1: Run a Virus Scan

The first step in checking for viruses on Windows 10 is to run a virus scan. Windows Defender, the built-in antivirus program on Windows 10, can easily scan your computer for any viruses and malware that may have infected your system. Simply open Windows Defender and click on “Scan Now” to start the scan.

Step 2: Use Malwarebytes

Although Windows Defender is a good antivirus program, it’s always a good idea to have a backup antivirus program. Malwarebytes is an excellent program that can detect and remove malware that may have slipped past Windows Defender.

Step 3: Check Your Installed Programs

Sometimes, viruses may disguise themselves as legitimate programs on your computer. It’s important to regularly check your installed programs to ensure that there are no suspicious programs that may have been installed without your knowledge.

Step 4: Clear Your Temp Folder

Viruses and malware can sometimes hide in your computer’s temporary folder. Clearing out the temporary folder can help to remove any viruses that may be hiding there.

Step 5: Update Your Windows 10

Keeping your Windows 10 updated with the latest security patches is important in protecting your computer from viruses and malware. Make sure to check for updates regularly and install them as soon as they become available.

Step 6: Use a Firewall

A firewall can help to protect your computer from attacks by blocking any unauthorized access to your system. Windows 10 comes with a built-in firewall that you can use, or you can opt for a third-party firewall program.

Step 7: Use a Virtual Private Network (VPN)

A Virtual Private Network (VPN) can help to protect your computer from attacks by encrypting your online activity and masking your IP address. There are many VPN programs available for Windows 10, both free and paid.

Step 8: Be Wary of Suspicious Emails and Websites

One of the most common ways that viruses and malware infect computers is through email attachments and malicious websites. Be careful when opening email attachments from unknown senders and always check the URL of any website before entering any personal information.

Step 9: Use Strong Passwords

A strong password can help to protect your computer from unauthorized access. Make sure to use a combination of upper and lowercase letters, numbers, and symbols to create a strong password that is difficult to crack.

Step 10: Use Two-Factor Authentication

Two-Factor Authentication (2FA) is an extra layer of security that requires you to enter a code in addition to your password. This can help to prevent unauthorized access to your computer.

Step 11: Disable Macros

Macros are small scripts that can run automatically when you open a file. Some viruses and malware use macros to infect your computer. Disable macros in all documents unless you need them for a legitimate purpose.

Step 12: Backup Your Data

Backing up your data regularly is important in case your computer becomes infected with a virus or malware. Make sure to back up your important files and data to an external hard drive or cloud storage service.

Additional Tips and Tricks

Tip 1: Use a Password Manager

Using a password manager can help to generate strong passwords and keep track of all your different login credentials.

Tip 2: Use Ad Blockers

Ad blockers can help to block ads and pop-ups that may be infected with malware.

Tip 3: Use Browser Extensions

Browser extensions such as WOT and HTTPS Everywhere can help to protect your computer while browsing the internet.

Tip 4: Avoid Public Wi-Fi

Public Wi-Fi networks are often insecure and can leave your computer vulnerable to attacks. Avoid using public Wi-Fi whenever possible.

Tip 5: Use File Encryption

File encryption can help to protect your sensitive files and data from unauthorized access. There are many encryption programs available for Windows 10.

Tip 6: Use a Password-Protected Screen Saver

A password-protected screen saver can help to prevent unauthorized access to your computer while you are away from your desk.

Tip 7: Keep Your Software Updated

Make sure to keep all your software and programs updated with the latest security patches to protect your computer from attacks.

Tip 8: Use Common Sense

Finally, the best defense against viruses and malware is to use common sense when browsing the internet and opening email attachments. If something looks suspicious, it probably is. Avoid clicking on links or downloading attachments from unknown sources.

Now that you know how to check for viruses on Windows 10 and how to protect your computer from attacks, make sure to follow these tips to keep your computer safe and secure.
