Top 9 Steps to Take When You Find Your Computer Infected with Malware

Even though your device is connected to the internet with a strong and stable Wi-Fi signal, you might still be unable to access the websites you want. Meanwhile, those around you can still browse the web without issues. This suggests that the problem is not with the internet connection, but rather that your computer has been compromised by malware. A practical solution is to use a 'clean' computer, free from viruses, to download the necessary software and then transfer it to your infected machine via a USB connection to clean it up. Other helpful tools, such as SD cards or external hard drives, can also be used for this purpose.

The best approach for this situation is to remove the malware to restore your computer to normal operation. First, identify the type of malware, common symptoms, and its specific name. Then, research how to handle and eliminate it. If you're not tech-savvy, you can seek help from experts in IT or visit trusted computer repair and service centers. However, be sure to gather information from multiple sources, evaluate it, and find the most effective solution. It's important not to start acting without understanding the issue, as you may inadvertently introduce more malware through fake software.

Today, software like Kaspersky, Anti-Malware, and Hitman Pro are commonly used to scan and detect malware. Download these programs from a virus-free computer, then transfer them to a USB drive and carefully plug it into your infected machine. For programs like Malwarebytes Anti-Malware, which require an internet connection to download the latest virus definitions, combining different programs can increase effectiveness. However, be cautious as you can only run one malware removal program at a time to avoid conflicts, slow performance, or negative effects on your system.

If you’re familiar with Clean Master for mobile, on your computer, tools like CCleaner, System Ninja, and Drive Tidy can help clean up unnecessary files and applications. After removing the malware, run another scan to check for any unnecessary content and delete it, improving your computer's performance. This final step ensures that any malware remnants are completely eradicated. Additionally, you can use Geek Uninstaller to remove any unwanted programs from your system.

When you notice signs like excessive pop-ups, slow performance, strange toolbars, or an inability to launch your browser despite being connected to the Internet, it indicates your computer is compromised. If you've discovered that your computer is infected with a virus, change the passwords of your accounts to prevent sensitive information theft, and to stop malware from using your accounts for illegal activities. Don't forget to use a password manager to create and remember strong passwords easily.

Although modern antivirus software is highly advanced and effective at detecting and mitigating security threats, sometimes it might not update quickly enough, allowing malware to spread unnoticed. Over time, your computer stores valuable data and files, so if it’s no longer secure, back them up to an external device like a USB drive or CD to prevent data loss. Be cautious when selecting files, as one might be infected with malware.

If you are using a default browser and search engines like Google or Cốc Cốc, but suddenly your search results are redirected to unfamiliar pages, be cautious. This could be a sign that your computer is infected with a virus that needs the Internet to transmit data and spread. Therefore, disconnect your computer from the Internet, even if you're using a desktop device.

Safe Mode refers to a troubleshooting option in which Windows starts with minimal devices and services, enabling users to diagnose and fix issues. By booting into Safe Mode, unnecessary programs are prevented from launching, reducing the risk of malware intrusion. To enter Safe Mode during startup, press F8, and the "Safe Mode" option will appear on the screen, or use the arrow keys to navigate through other choices. If Windows fails to boot, you can use a rescue disk with antivirus software—free products from well-known companies like Kaspersky, Avira, and AVG can help eliminate malware.
