Is Your Computer Acting Strange?
A Simple Guide for Seniors to Spot Malware.
If your computer has ever started acting “funny” and you weren’t sure why, you’re not alone. Many seniors tell me, “I thought I broke something!” — but in most cases, the computer is reacting to something called malware.
Malware isn’t a real bug, but it behaves like one: sneaky, annoying, and disruptive. The good news is that you can learn to spot the signs early and take simple steps to protect yourself.
How to Tell When Something’s Wrong
The easiest way to think about malware is this:
Your computer starts doing things you didn’t ask it to do.
Here are the most common signs seniors notice:
- Pop ups appear out of nowhere — especially ones shouting “Your computer is infected!”
- Your internet homepage suddenly looks different or unfamiliar
- New toolbars or strange icons appear at the top of your browser
- Your computer becomes slow, freezes, or makes unusual noises
- You type in a website (like google.com) but get taken somewhere else
- Programs you never installed suddenly show up
- Your laptop gets warm or the battery drains quickly
- Friends tell you they got emails from you that you didn’t send
- Security warnings appear that don’t look like the usual Windows messages
A simple rule of thumb: If two or more strange things happen at once, it’s time for a malware check.
What To Do If You Suspect Malware
The most important thing is don’t panic. Scammers rely on fear to trick people into clicking or calling.
Here’s a calm, step by step plan:
1. Don’t click anything
Especially don’t call any phone number shown in a pop up.
Those numbers go straight to scammers.
2. Close your browser
If the pop up won’t close:
- Press Ctrl + Alt + Delete
- Choose Task Manager
- Click your browser (Chrome, Edge, Firefox)
- Select End Task
This safely shuts down the scam window.
3. Run a Quick Scan with Microsoft Defender
This tool is built into Windows — no downloads needed.
- Click Start
- Type Windows Security
- Choose Virus & threat protection
- Click Quick Scan
If it finds anything, follow the instructions on the screen.
4. Optional: Run a second scan
Two excellent, senior friendly tools:
- Malwarebytes Free
- AdwCleaner (great for pop ups and browser hijackers)
Click Scan, then Quarantine or Remove.
5. Restart your computer
This helps finish the cleanup.
6. Check your browser
After restarting:
- Open your browser
- Look at your homepage
- Check your extensions
Remove anything you don’t recognize.
7. If you’re unsure, ask for help
Reach out to:
- A trusted family member
- Your senior tech helper (me)
- A local computer shop
Never call a number from a pop-up.
A Final Word of Encouragement
You don’t need to be “tech savvy” to stay safe online. You just need to know what to look for and what to do next.
If your computer starts acting strange, close the window. Run a scan. Call someone you trust.
You’ve got this — and you’re not alone.
When your computer gets malware, it can feel scary; you are not sure whether to trust if it’s real or not! You need to feel safe and secure when you are using your computer, not be surprised by pop-ups that claim Microsoft Windows tech support is standing by to fix your computer!
