Ever get that nagging feeling that something’s off with your computer? If you’re using Windows 10, there are some telltale signs that might indicate your computer has a virus. These indicators can range from slow performance to weird pop-up messages. In this guide, we’ll walk you through the steps to check if your computer is infected and give you tips to keep it safe.

How to Know if Your Computer Has a Virus Windows 10

In this section, we’ll cover the steps to help you identify if your Windows 10 computer has a virus. This includes checking for unusual behavior, running antivirus scans, and examining system performance.

Step 1: Check for Unusual Behavior

First things first, observe if your computer is acting weird.

Is your computer suddenly very slow? Are programs crashing frequently? These could be signs of a virus. Pay attention to anything that doesn’t feel normal.

Step 2: Run Windows Defender

Open Windows Defender to scan your computer for malware and viruses.

Windows Defender is built into Windows 10 and offers real-time protection. Go to Settings > Update & Security > Windows Security > Virus & threat protection. Click "Quick scan" to start.

Step 3: Check Task Manager

Open Task Manager to see if any unusual processes are running.

Press Ctrl + Shift + Esc to open Task Manager. Look for processes you don’t recognize. If you find any, do a quick online search to see if they are legitimate.

Step 4: Examine Browser Behavior

Look out for strange browser behavior, like unexpected pop-ups or redirects.

If your browser is acting up, it might be a sign of adware or a browser hijacker. Reset your browser settings and remove any suspicious extensions.

Step 5: Run a Full System Scan

Use a third-party antivirus program to conduct a comprehensive scan.

Sometimes, a quick scan isn’t enough. Use reputable antivirus software to perform a full system scan, which can catch deeper, hidden threats.

After completing these steps, your computer should be in better shape. If you did find a virus, follow your antivirus program’s recommendations to remove it. Your computer should start to run smoother and behave normally again.
