5 Signs Your Computer Might Have a Virus (And What to Do Next)

Staying safe in the digital world starts with knowing the early signs that something is wrong with your computer. Malware and viruses often sneak in quietly — but your device will usually show you clues before the problem becomes serious.

Whether you use your computer for work, school, business, or everyday life, recognizing these symptoms early can save you time, stress, and money. Here are the top signs your computer may be infected and what you should do next.

1. Your Computer Suddenly Runs Slower

If your device feels like it's moving through mud — freezing, lagging, or taking forever to load — it may be struggling with hidden malware running in the background.
👉 Why this matters: Viruses use your system resources, making everything slower.

2. Pop-Ups Start Appearing (Even When Your Browser Is Closed)

Unexpected ads, warnings, or “security alerts” are major red flags.
👉 Tip: Never click “clean now” or “scan now” on random pop-ups — many are fake.

3. Your Browser Opens Random Tabs or Redirects You

If your browser takes you to strange websites or search engines you didn’t choose, you may have adware or a browser hijacker.
👉 This includes:

• New toolbars

• Extensions you didn't install

• Homepage changes

4. Programs Crash or Won’t Open

Malware often corrupts system files, causing apps to close unexpectedly or stop launching altogether.

5. You Notice Unknown Programs or Strange Activity

Keep an eye out for things you didn’t install:

• Random applications

• Antivirus warnings you didn’t generate

• High CPU usage when you’re not doing anything

If something looks suspicious, it probably is.

What To Do Next

If you’re experiencing one or more of these symptoms, don’t ignore them. Acting early prevents data loss, identity theft, and further damage.

✓ Step 1: Stop downloading or installing anything new

This prevents the infection from spreading.

✓ Step 2: Disconnect from Wi-Fi

This stops the malware from sending data out or bringing more in.

✓ Step 3: Get a professional computer diagnosis

Many infections aren’t visible to the average user — but they leave digital fingerprints I can detect quickly.
