Detecting and Removing Malware
Is your computer acting strangely - freezing often, running slowly, or showing strange pop-ups? There’s a good chance it might be infected with malware. Malware is unwanted software designed to cause damage, steal data, or disrupt how your computer works. The good news is, detecting and removing malware can be simple, and this guide is here to walk you through it.
If you're on the Central Coast and not confident tackling malware yourself, Zelrose IT is here to help with fast, friendly support - either remotely or in-person.
What Is Malware?
Malware (short for malicious software) includes viruses, spyware, ransomware, adware, and more. It can:
Slow down or freeze your computer
Display unexpected ads or pop-ups
Redirect your web browser
Steal personal data like passwords or bank info
Block access to your files or programs
How to Tell If Your Computer Has Malware
You might notice:
Programs or windows opening on their own
Unusual pop-ups or warning messages
Very slow performance or frequent freezing
Antivirus warnings or update issues
New browser toolbars or homepage changes
If something feels “off,” it’s better to check than ignore it.
Step-by-Step Guide: Detecting Malware
1. Disconnect from the Internet
If you suspect malware, turn off Wi-Fi or unplug your internet cable.
This prevents further data theft or malware spreading.
2. Boot into Safe Mode
Safe Mode disables most non-essential programs, making it easier to scan for malware.
See our guide: How to Boot into Safe Mode (Windows/Mac)
3. Run a Malware Scan
Use a trusted antivirus or anti-malware program to scan your entire system:
Windows Defender (built-in)
Go to Settings > Update & Security > Windows Security > Virus & threat protection
Click Scan options, then choose Full Scan
Recommended Free Tools
Malwarebytes (Free version) – www.malwarebytes.com
Bitdefender Free Antivirus
Avast Free Antivirus
Download these tools only from their official websites.
4. Quarantine or Remove Infected Files
Once malware is detected:
Follow the program’s instructions to quarantine or delete the infected files.
Restart your computer after removal.
Step-by-Step: Removing Malware from macOS
Use trusted Mac security software such as:
Malwarebytes for Mac
Avast Security for Mac
Run a full system scan.
Follow prompts to remove/quarantine threats.
Restart your Mac when complete.
What If Malware Won’t Go Away?
Some infections are tricky and may keep coming back. If you’re dealing with persistent malware:
Boot into Safe Mode and rerun the scan.
Try a second malware removal tool.
Restore your system using System Restore (Windows) or Time Machine (Mac).
If it’s still not working, it’s time to call in the pros - Zelrose IT can fully clean your system and secure it against future threats.
Preventing Malware in the Future
Keep Windows and macOS up to date
Use real-time antivirus protection
Don’t click suspicious links or email attachments
Avoid downloading from untrusted websites
Install a browser extension that blocks pop-ups and trackers (like uBlock Origin)
